Answer:

There is a possibility that it will be converted to another form, but based on the context the answer is A. It is stored as potential energy.

Explanation:

This is because potential energy means that the energy has the potential to release energy to do work, but it has not yet. So if it has not been transferred to anything, and the object has already had the ability to have potential energy, then it will stay as potential until released.

Olegator [25]

By Boyle's law:

P₁V₁ = P₂V₂

70*8 = P₂*4

P₂*4 = 70*8

P₂ = 70*8/4 = 140

P₂ = 140 kiloPascals.

Answer:

$v=wr$

Explanation:

Tangent and Angular Velocities

In the uniform circular motion, an object describes the same angles in the same times. If $\theta$ is the angle formed by the trajectory of the object in a time t, then its angular velocity is

$\displaystyle w=\frac{\theta}{t}$

if $\theta$ is expressed in radians and t in seconds the units of w is rad/s. If the circular motion is uniform, the object forms an angle $2\theta$ in 2t, or $3\theta$ in 3t, etc. Thus the angular velocity is constant.

The magnitude of the tangent or linear velocity is computed as the ratio between the arc length and the time taken to travel that distance:

$\displaystyle v=\frac{\theta r}{t}$

Replacing the formula for w, we have

$\boxed{ v=wr}$
