What is the difference between static and dynamic flexibility ?

Answers

Static stretches are those in which you remain in a single position—standing, sitting, or lying still—for up to 45 seconds. Dynamic stretches are regulated motions that get your ligaments, muscles.

Stretches that are static versus those that are dynamic:

Movement is included into dynamic stretches, such as lunges with a torso twist. As opposed to dynamic stretches, static stretches include holding a stretched position for a while. Stretches that are static include the triceps stretch and the butterfly stretch.

A swimmer might, for instance, circle their arms before entering the water. A series of movements to get the body moving before engaging in any kind of exercise can also be considered dynamic stretches.

A cylindrical bucket of liquid (density rho) is rotated about its symmetry axis, which is vertical. If the angular velocity is ω, show that the pressure at a distance r from the rotation axis is P=P 0+ 21rhoω 2r 2where P 0 is the pressure at r=0,

Answers

Answer:

To derive the formula for the pressure at a distance r from the rotation axis, you can use the principle of hydrostatic equilibrium. This states that the pressure at a point in a fluid is equal in all directions and the net force on a fluid element is equal to zero.

Consider a small cylindrical element of fluid at a distance r from the rotation axis, as shown in the diagram below. The dimensions of the element are dr in the radial direction, 2πr in the circumferential direction, and h in the vertical direction. The weight of the element is equal to the product of its volume, density, and the acceleration due to gravity: W = (2πr)(dr)(h)(ρ)(g). The pressure at the top and bottom faces of the element is P + dP, where P is the pressure at the point and dP is a small change in pressure. The forces acting on the element are the weight of the element, the pressure force at the top face, and the pressure force at the bottom face.

What is Atmosphere?

A layer (or layers) of gases that surround a planet and are held together by the gravitation of the planetary body is known as an atmosphere. Whenever the gravity is strong as well as the atmospheric temperature is low, a planet preserves its atmosphere. The five separate layers of the atmosphere are a result of the temperature variations that occur with height.

The layer of gases that covers Earth and contains the air we breathe is known as an atmosphere. The gravitational pull of the planet's neighbor, Earth, keeps it close to the surface. To gauge air pressure, use a barometer. The three primary components of the atmosphere are nitrogen, oxygen, and argon.

Answers

The parallax formula is used to calculate the distance to a star based on the parallax angle, which is the angle between a star's position in the sky when observed from two points in the Earth's orbit six months apart.

What is distance ?

Distance is the measure of how far apart two objects or points are. It is typically measured in units such as meters, kilometers, miles, or light years. Distance can also be measured in terms of time, such as the time it takes to travel from one point to another.

Distance can either be measured directly, by measuring the physical gap between two points, or indirectly, by using a map, compass, or other navigation tool.

Part A
Distance = 1/0.7420 = 1.3481 parsecs
Distance = 1.3481 * 3.26156 = 4.39 light-years
Part C
Distance = 1/0.2860 = 3.4984 parsecs
Part D
Distance = 3.4984 * 3.26156 = 11.39 light-years
The parallax formula is used to calculate the distance to a star based on the parallax angle, which is the angle between a star's position in the sky when observed from two points in the Earth's orbit six months apart. The formula is simply distance = 1/parallax angle.

Diffusion dialysis is referred to be a spontaneous separation technique since the concentration gradient primarily drives the separation process. A membrane separation procedure is DD.

Diffusion is the movement of a solute along a concentration gradient through a membrane. Small molecules are eliminated in this manner during hemodialysate. Diffusion is the net transfer of a substance from a location of high concentration to a region of low concentration, according to physicists and chemists.

Diffusion in hemodialysis is formally defined as the transport of solutes as a result of random molecular motions down its concentration gradient through a semipermeable membrane. Diffusion is how most toxins are removed during dialysis.

If you throw a ball up in the air at a speed of 14.9 m/s, how fast (in m/s) will it be moving when you catch it

Answers

When you catch a ball you threw in the skies at the a speed exceeding 14.9 m/s, it will also travel at the same speed when you catch it.

How fast is it?

Time is a scalar that indicates the direction and speed of an object's motion. Usually, it is expressed in terms of measures of speed per amount of time, including m / sec (m/s) or miles each hour (mph) (mph). Speed is the size of velocity, a vector number that indicates both the direction and the speed of motion. Pace is a positive number with a unit of distance traveled per second.

When something is launched into air, it is exposed to the downward-moving force of gravity. The item accelerates downward at a velocity of 9.8 m/s2 as a result of this force

The object will slow down so that it rises and accelerate up as it lowers due to this acceleration. However, if there is very little time between the ball's release and the catch, the ball won't have a chance to slow down much. As a result, the pace at which i catch the ball will be quite similar to the pace at which originally threw it.

The ball will therefore continue to move at the same pace that it did when thrown.

A truck with mass of 3,250 kg traveling with a velocity of 25.0 m/s hits a car at rest. After the collision, the truck moves with a velocity of 19.0 m/s. The car has a mass of 2,820 kg. If the two vehicles do not stick together, how fast is the car moving after the collision?

Answers

Answer:

6.9 m/s

Explanation:

This is a conservation of momentum problem, so the total momentum before the collision must equal the total momentum after the collision.

P = mv

m1v1 + m2v2 (before) = m1v1 + m2v2 (after)

(3250kg)(25.0 m/s) + (2820 kg)(0m/s) = (3250 kg)(19.0 m/s) + (2820 kg)(v2)

Now you can solve for the v of the car after the collision:

81250 kg·m/s + 0 = 61750 kg·m/s + (2820 kg)v2

19500 kg·m/s = (2820 kg)v2

v2 = 19500 kg·m/s / 2820 kg = 6.9 m/s

Four particles with masses 4 kg, 4 kg, 4 kg, and 7 kg are connected by rigid rods of negligible mass as shown. Assume the system rotates in the xy plane about the z axis (origin, O) with an angular speed of 9 rad/s. Find the rotational energy of the system about the x axis.

Answers

The rotational Kinetic energy of the system about X axis is 24624 J.

Let the distance of the mass 4kg, from O is r1,

r = √(4² + 4²)

r = √32m

The distances of masses to the rotation axis is same -

say,

r1 = r2 = r3 =r4 = √32

Hence,

I = ∑ mi r1²

I = r² ∑(m1 + m + m3 + m4)

= 32(19)

I = 608 Kg m²

We know that rotational energy of system is given as,

A 65.6 kg ice skater moving to the right with a velocity of 2.65 m/s throws a 0.142 kg snowball to the right with a velocity of 32.7 m/s relative to the ground. What is the velocity of the ice skater after throwing the snowball

Answers

The velocity of the ice skater after throwing the snowball is 0.08m/s.

Given data as per the question is,

Mass of ice skater= 65.6kg

Velocity 1= 2.65m/s

Mass of the Snowball= 0.142kg

Velocity 2= 25.2m/s

Conditions before snowball is thrown:

Total mass of skater + snowball = 65.6+ 0.142 = 65.742kg

Total Momentum of skater + snowball = mv = 65.6 x 2.65 = 173.84 kgm/s

Conditions after snowball is thrown:

Let's call the velocity of the skater V.

Total momentum = momentum of skater + momentum of snowball

=65.6V + (4.6434)

= 65.6V + 4.6434

173.84  = 65.6V+4.6434

173.84- 4.6434= 65.6V

169.19=65.6 V

V= 175.156/69.22

V = 2.57m/s

The total momentum after catching the snowball is mV or:

(65.6 + 0.142) x V

So:

4.6434= 65.742V

V= 5.544/69.22

V=0.08m/s
