Answer:

Stress = 4.67 * 10^-7 N/m²

Explanation:

Young's modulus of the material = Stress/Strain

Given

Young's modulus  = 228 x 10^9 Pa

Stress =  106,483 Pa

Required

Strain

From the formula;

Strain = Stress/Young modulus

Strain =  106,483 /228 x 10^9

Stress = 4.67 * 10^-7 N/m²

Answer:

Because there are other elements that get in touch with it. And over time with, evolution, erosion and temperature their particles tend to mix. So what once was very common became mixed over time.

Explanation:

Rectangular Components of a Vector

A 2D vector can be expressed in several forms. The rectangular form gives its two components, one for each axis (x,y). The polar form gives the components as the pair (r,θ) being r the magnitude and θ the angle.

When the magnitude and angle of the vector are given, the rectangular components are calculated as follows:

[tex]v_x=v\cos\theta[/tex]

[tex]v_y=v\sin\theta[/tex]

Where v is the magnitude of the vector and θ is the angle with respect to the x positive direction.

The cart is moving at v=55 m/s at θ=25°, thus:

[tex]v_x=55\cos 25^\circ[/tex]

[tex]v_x=49.85\ m/s[/tex]

The horizontal component of the velocity is 49.85 m/s.

Answer:

x = ~0.1289 m/s^2

Explanation:

We can use one of the kinematic formulas. We see that the equation doesn’t contain the final velocity, so we use the kinematic equation d = v_0t + (1/2)at^2.

Since the train started from rest, the initial velocity, v_0, is 0. Thus, the equation becomes:

d = (1/2)at^2

Note that 5 minutes is 300 seconds and 5.8 km is 5800 m. Substituting the values we are given, we get:

5800 m = (1/2)(x m/s^2)(300 s)^2 = (45000 s^2)(x m/s^2)

Dividing by 45,000 on both sides, we get:

x = ~0.1289 m/s^2

Answer:

553.74≤x≤578.26

Explanation:

The formula for calculating the confidence interval is expressed as

CI = xbar±(z×s/√n)

xbar is the mean = 562

s is the standard deviation = 26.1

n is the sample size = 35

z is the z score at 90% CI = 1.645

Substitute the values into the formula

CI = xbar±(z×s/√n)

CI = 561±(1.645×26.1/√35)

CI = 561±(1.645×4.412)

CI = 561±7.257

CI = {561-7.257, 571+7.257}

CI = {553.74, 578.26}

Hence the 90% confidence interval estimate of the name of the population is 553.74≤x≤578.26

Answer:

Acceleration

Explanation:

The choice from the given option which is not a force is acceleration.

Acceleration is defined as the rate of change of velocity of a body with time;

   Acceleration  = [tex]\frac{change in velocity}{time}[/tex]  

Force is a pull or push on a body. The product of mass and acceleration is force.

Answer:

A football flying through the air

Explanation:

when an object has projectile motion it is moving through the air

From the given options, the football flying through the air is the prime example of projectile motion. (option d)

Projectile motion refers to the motion of an object that is launched into the air and moves under the influence of gravity alone. It follows a curved path known as a projectile trajectory. Among the options provided, the example that best represents projectile motion is a football flying through the air.

When a football is kicked or thrown, it experiences an initial force that propels it forward. However, as soon as it leaves the kicker's or thrower's hand or foot, the only force acting on it is gravity. Gravity pulls the football downward, causing it to follow a curved path. The shape of the path depends on the angle at which the football is launched and its initial velocity.

During its flight, the football follows a parabolic trajectory, moving both horizontally and vertically. The horizontal component of its motion remains constant, while the vertical component experiences a downward acceleration due to gravity. This combination of horizontal and vertical motion creates the characteristic curved path of projectile motion.

Therefore, option (d) is correct.

Answer:

My best friend lol cuz since quarantine i didn't see her

Answer:

It's Newton's third law. For every known reaction, there is a equal and opposite reaction.

Explanation:

The mallet which hits the ball with an action force, the ball exerts a reaction force on the mallet as explained by the Newton's third law. Thus, the correct option is 3.

Newton's third law states that for every action (force) in nature there is an equal and opposite force or reaction. An example of third law of motion is that the mallet hits the ball with an action force, then the ball exerts a reaction.

If an object A exerts a force on the object B, then object B must also exert a force of equal magnitude and in the opposite direction back on object A. The law represents a certain symmetry in the nature that the forces always occur in pairs, and one body cannot exert a force on another without experiencing any kind of force itself.

Therefore, the correct option is 3.

Explanation:

Answer:

a. 0.199 ms b. 5.03 kHz c. 0.1 mJ

Explanation:

a. The period of oscillation of an L-C circuit is T = 2π√(LC) where L = inductance = 20 mH = 20 × 10⁻³ H and C = capacitance = 0.005 mF = 5 × 10⁻⁶ F.

So, T = 2π√(LC)

= 2π√(20 × 10⁻³ H × 5 × 10⁻⁶ F)

= 2π√(100 × 10⁻¹¹)

= 2π√(10 × 10⁻¹⁰)

= 2π(3.16 × 10⁻⁵)

= 19.87 × 10⁻⁵

= 1.987 × 10⁻⁴ s

= 1.99 × 10⁻⁴ s

= 0.199 × 10⁻³ s

= 0.199 ms

b. frequency , f = 1/T where T = period = 0.199 × 10⁻³ s.

So, f = 1/0.199 × 10⁻³ s

= 5.03 × 10³ Hz

= 5.03 kHz

c. The electromagnetic energy E = 1/2Li² where L = inductance = 20 × 10⁻³ H and i = current = 100 mA = 0.1 A

So, E = 1/2Li²

= 1/2 × 20 × 10⁻³ H × (0.1 A)²

= 0.1 × 10⁻³ J

= 0.1 mJ

Answer:

The net force acting on the object is 0 N

Explanation:

Newton's Second Law of Forces

The net force acting on a body is proportional to the mass of the object and its acceleration.

The net force can be calculated as the sum of all the force vectors in each rectangular coordinate separately.

The image shows a free body diagram where four forces are acting: two in the vertical direction and two in the horizontal direction.

Note the forces in the vertical direction have the same magnitude and opposite directions, thus the net force is zero in that direction.

Since we are given the acceleration a =0, the net force is also 0, thus the horizontal forces should be in equilibrium.

The applied force of Fapp=10 N is compensated by the friction force whose value is, necessarily Fr=10 N in the opposite direction.

The net force acting on the object is 0 N
