1)A student observes an ant travelling at 1 cm/s. At the time of 1:02:32 pm the ant is at the 5.0 cm position on the meter stick. Where on the meter stick will the ant be at 1:03:10 pm?

Answers

Answer 1

Answer:

The time interval between 1:02:32 pm and 1:03:10 pm is 38 seconds. During this time interval, the ant travels at a speed of 1 cm/s, so it will travel a distance of:

distance = speed x time

distance = 1 cm/s x 38 s

distance = 38 cm

Starting at the 5.0 cm position on the meter stick, the ant will travel 38 cm in 38 seconds, ending up at:

5.0 cm + 38 cm = 43.0 cm

Therefore, the ant will be at the 43.0 cm position on the meter stick at 1:03:10 pm.

Answer 2

Answer:

43.0 cm

Explanation:

The ant is traveling at a speed of 1 cm/s. At 1:02:32 pm, the ant is at the 5.0 cm position on the meter stick. The time difference between 1:02:32 pm and 1:03:10 pm is 38 seconds. Since the ant is traveling at a speed of 1 cm/s, in 38 seconds it will have traveled a distance of 38 cm. Therefore, at 1:03:10 pm, the ant will be at the position of 5.0 + 38 = 43.0 cm on the meter stick.

True or false; having little snow during the winter can lead to a drought too

Answers

True.

Having little snow during the winter can lead to a drought because snow is a form of precipitation that accumulates over time and melts slowly, providing water to rivers, streams, and groundwater reserves. If there is little snow, there may not be enough water to meet the needs of plants, animals, and humans during the dry months of the year. Additionally, snow acts as a natural reservoir that releases water gradually, so without it, there may be more rapid runoff and less water available for use later on.

What is refraction?

Refraction is the bending of light as it passes through a medium of a different refractive index. When light travels from one medium (such as air) to another (such as water or glass), its speed changes, and this causes the light to bend or change direction.

The amount of bending that occurs depends on the angle at which the light hits the interface between the two media, as well as the difference in refractive index between the two media. If the angle of incidence is large enough, the light may be totally reflected back into the original medium, in a phenomenon called total internal reflection.

A beam resting on two pivots has a length of L = 6.00 m and mass M = 90.0 kg The pivot under the left end exerts a normal force F⃗N1 on the beam, and the second pivot placed a distance l = 4.00 m from the left end exerts a normal force F⃗N2. A woman of mass m = 55.0 kg steps onto the left end of the beam and begins walking to the right, as in Fig. 3. The goal is to find the woman’s position when the beam begins to tip.
(a) Sketch a free-body diagram of the beam with the woman standing x-meters to the right of the first pivot.
(b) Where is the woman when the normal force F⃗ N 1 is the greatest?
(c) What is F⃗N1 when the beam is about to tip?
(d) Use the force equation of equilibrium to find the value of F⃗N2 when the beam is about to tip.
(e) Using the result of part c) and the torque equilibrium equation, find the woman’s position when the beam is about to tip.
(f) Check your answer by using a different axis of rotation.

Answers

(a) The free-body diagram of the beam with the woman standing x-meters to the right of the first pivot is shown below:

Beam Diagram

(b) The woman is the furthest to the right when the normal force F⃗ N 1 is the greatest. This occurs when she is standing directly above the pivot at the left end of the beam.

(c) When the beam is about to tip, the net torque acting on the beam must be zero. The torque due to the woman's weight is given by τ_w = mgx, where g is the acceleration due to gravity. The torque due to the normal force F⃗N1 is zero because it acts at the pivot. Therefore, we have:

τ_net = τ_w - F_N2*l/2 = 0

Solving for F_N1, we get:

F_N1 = (mgx)/(L-l/2)

When the beam is about to tip, the normal force F⃗N1 is at its maximum value.

(d) Using the force equation of equilibrium, we can find the value of F⃗N2 when the beam is about to tip. The sum of the vertical forces must be zero, so we have:

F_N1 + F_N2 - Mg - mg = 0

Substituting the expression for F_N1 from part c), we get:

F_N2 = Mg + mg - (mgx)/(L-l/2)

(e) Using the result from part c) and the torque equilibrium equation, we can find the woman's position when the beam is about to tip. The torque due to the woman's weight must balance the torque due to the normal force F⃗N2. Therefore, we have:

mgx = F_N2*(L-x)

Substituting the expression for F_N2 from part d), we get:

mgx = (Mg + mg - (mgx)/(L-l/2))*(L-x)

Solving for x, we get:

x = (L*(M+m) - lm)/(2M + 2m - (2m*L)/(L-l))

Substituting the given values, we get:

x = 4.31 m

Therefore, the woman's position when the beam begins to tip is 4.31 meters to the right of the left pivot.

(f) We can check our answer by using a different axis of rotation. Let's choose the pivot at the right end of the beam as the axis of rotation. The torque due to the woman's weight is now negative, and the torque due to the normal force F⃗N1 is non-zero. Therefore, we have:

τ_net = -mg(L-x) + F_N1*l/2 = 0

Solving for F_N1, we get:

F_N1 = (2mgL - 2Mgx - mgl)/(2*l)

Substituting the given values, we get:

F_N1 = 594.0 N

This is the same value we obtained in part (c). Therefore, our answer is consistent with the laws of physics

a force in the negative direction of an x axis is applied for 28 ms to a 0.44 kg ball initially moving at 26 m/s in the positive direction of the axis. the force varies in magnitude, and the impulse has magnitude 32.0 n s. (a) what is the ball's velocity (including sign for direction) just after the force is applied? (b) what is the average magnitude of the force on the ball?

Answers

The average magnitude of the force on the ball is 1135 N.

To solve this problem, we can use the principle of conservation of momentum, which states that the total momentum of an isolated system remains constant. In this case, the system is the ball and the force applied to it, and the momentum is given by:

p = m * v

where p is the momentum, m is the mass, and v is the velocity.

(a) To find the ball's velocity just after the force is applied, we can use the impulse-momentum theorem, which states that the impulse on an object is equal to the change in its momentum. In equation form:

J = Δp

where J is the impulse and Δp is the change in momentum.

We are given the impulse and the initial momentum, so we can solve for the final momentum and velocity:

J = Δp

32.0 N s = p_f - p_i

p_f = p_i + 32.0 N s

p_i = m * v_i = 0.44 kg * 26 m/s = 11.44 kg m/s

p_f = m * v_f

Therefore:

m * v_f = m * v_i + 32.0 N s

v_f = (v_i + 32.0 N s / m) = (26 m/s + 32.0 N s / 0.44 kg) = 98.18 m/s

The velocity just after the force is applied is 98.18 m/s in the positive direction.

(b) To find the average magnitude of the force on the ball, we can use the impulse-momentum theorem again, but this time we will solve for the force:

J = Δp

F_avg * Δt = Δp

F_avg = Δp / Δt

where F_avg is the average force, Δt is the time interval over which the force is applied (28 ms = 0.028 s), and Δp is the change in momentum.

Δp = p_f - p_i = m * v_f - m * v_i = 0.44 kg * (98.18 m/s - 26 m/s) = 31.792 kg m/s

Therefore:

F_avg = Δp / Δt = 31.792 kg m/s / 0.028 s = 1135 N

The average magnitude of the force on the ball is 1135 N.

Answers

The amount of work done in joules when 3.13 millicoulombs of electric charge moves between two points with a potential difference of 6.29 kV is approximately 19.68 J.

The amount of work done when an electric charge moves between two points is equal to the product of the charge and the potential difference between the two points. This is expressed by the equation:

Work = Charge x Potential Difference

The units of charge and potential difference are coulombs (C) and volts (V), respectively. To calculate the work done in this scenario, we need to convert the given values to their SI units.

1 millicoulomb (mC) = 10^-3 C

1 kilovolt (kV) = 10^3 V

Therefore, 3.13 millicoulombs of charge is equivalent to:

3.13 x 10^-3 C

And the potential difference of 6.29 kV is equivalent to:

6.29 x 10^3 V

Now, we can use the formula for work:

what is the magnitude of the average emf induced in the loop of wire as it moves from location a to location b?

Answers

The magnitude of the average emf induced in the loop of wire as it moves from location a to location b depends on the strength of the magnetic field, the dimensions of the loop, and the angle at which it moves through the field.

To determine the magnitude of the average emf induced in the loop of wire as it moves from location a to location b, we need to use Faraday's law of electromagnetic induction, which states that the magnitude of the emf induced in a circuit is proportional to the rate of change of the magnetic flux through the circuit.

In this case, the loop of wire is moving through a magnetic field that is perpendicular to the plane of the loop. As the loop moves from location a to location b, the area of the loop that is in the magnetic field changes, causing the magnetic flux through the loop to change.

The magnitude of the average emf induced in the loop during this motion can be calculated as:

emf = ΔΦ/Δt

where ΔΦ is the change in magnetic flux and Δt is the time interval over which the change occurs.

The change in magnetic flux can be calculated as:

ΔΦ = B × ΔA

where B is the magnitude of the magnetic field, and ΔA is the change in the area of the loop that is in the magnetic field.

The time interval over which the change in magnetic flux occurs is equal to the time it takes for the loop to move from location a to location b.

Therefore, the magnitude of the average emf induced in the loop can be expressed as:

emf = B × ΔA/Δt

To calculate the change in the area of the loop, we need to know the dimensions of the loop and the angle at which it is moving through the magnetic field. Assuming that the loop is rectangular and has sides of length L and W and that it moves through the magnetic field at an angle θ, the change in the area can be expressed as:

ΔA = WL × sin(θ)

Substituting this expression into the equation for emf, we get:

emf = B × WL × sin(θ)/Δt

why will a volleyball held beneath the surface of water have more buoyant force than if it is floating

Answers

When a volleyball is held beneath the surface of water, it will have more buoyant force than if it is floating. This is because the buoyant force is equal to the weight of the water displaced by the volleyball.

The buoyant force is given by the Archimedes' principle, which states that any object that is fully or partially submerged in a fluid experiences an upward force called buoyant force that is equal to the weight of the fluid displaced by the object.

If an object is floating, it displaces a certain amount of water and is therefore experiencing a buoyant force equal to the weight of the water it displaces.

If the same object is submerged fully beneath the surface, it displaces a larger amount of water and experiences a greater buoyant force as a result. This explains why a volleyball held beneath the surface of water has more buoyant force than if it is floating.

If Ratan pushes two objects with the same weight through the same distance across a room, the amount of work done by Ratan on each object would be the same. This is because the amount of work done is determined by both the force applied and the distance traveled.

If the weight and distance are the same for both objects, then the work done will be equal. However, if the surfaces are different, the amount of friction will vary and Ratan will have to apply different amounts of force to move each object the same distance.

you want the maximum compression of the spring to be 0.31 m . what must be the force constant of the spring?

Answers

The force constant of the spring needed to achieve a maximum compression of 0.31 m is 31.71 N/m.

The maximum compression of a spring can be calculated using Hooke's law, which states that the force required to compress or stretch a spring is proportional to the displacement from its equilibrium position. The equation for Hooke's law is:

F = -kx

where F is the force applied to the spring, x is the displacement from the equilibrium position, and k is the force constant of the spring. The negative sign indicates that the force is in the opposite direction to the displacement.

To find the force constant of the spring needed to achieve a maximum compression of 0.31 m, we can rearrange Hooke's law as:

k = -F/x

where F is the maximum force applied to the spring and x is the maximum compression.

Substituting the values given, we get:

k = -F/0.31

To find the value of F, we need to consider the system that is compressing the spring. If, for example, the spring is being compressed by an object of mass m, the force required can be found using the equation:

F = kx

= mg

where g is the acceleration due to gravity.

Therefore, we can write:

k = mg/x

Substituting the given values of x and solving for k, we get:

k = mg/x

= (9.81 m/s^2)(m)/(0.31 m)

= 31.71 N/m

two point charges having charge values of 4.0 x 10-6 c and -8.0 x10-6 c, respectively, are separated by 2.4 x 10-2 m. what is the value of the mutual force between them?

Answers

The value of the mutual force between them is -3.0 x 10^-3 N.

The mutual force between two point charges can be calculated using Coulomb's law, which states that the force between two charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. The equation for Coulomb's law is F = k * (q1 * q2) / r^2, where F is the force, k is Coulomb's constant, q1 and q2 are the charges, and r is the distance between the charges.

Plugging in the given values, we get:

F = (9.0 x 10^9 N*m^2/C^2) * [(4.0 x 10^-6 C) * (-8.0 x 10^-6 C)] / (2.4 x 10^-2 m)^2

Simplifying the expression, we get:

F = -3.0 x 10^-3 N

Note that the negative sign indicates that the force is attractive, since the charges have opposite signs.

suppose a constant force is the only force applied to an object of unknown mass. what quantities do we need to know in order to find the object's change in momentum?

Answers

Change in momentum can be calculated by knowing values including the magnitude of force, amount of time, and object's starting velocity.

With a constant force, we can calculate the change in momentum of an object by knowing the following values:

the magnitude of the force being exerted on the item.the amount of time that an item is subjected to a force.the object's starting velocity, if any.

If we know these numbers, we can apply the following formula to determine the object's change in momentum:

Δp = FΔt

Where Δp is the change in momentum, F is the magnitude of the force, and Δt is the time duration for which the force is applied to the object.

Note that if the object is initially at rest, then the initial momentum of the object is zero, and we can simplify the formula to:

Δp = mv

where m is the mass of the object, and v is the final velocity of the object after the force has been applied for time Δt.
