Answer:
s=vt2 just simplify all into metric units first
The elastic potential energy stored in a spring is given by:

where k is the spring constant, and x=0.5 is the compression of the spring. Re-arranging the formula and using E=5 J, we find the spring constant:

When a net torque is applied to a rigid object, it always produces a <em>change in angular velocity</em>. <em>(e.)</em>
The best answer is
C) atmosphere and geosphere
The wind constitutes the atmosphere, since it is the movement of air, the gas that surrounds the planet. The geosphere constitutes the surface of the earth, and is used to refer to the cryosphere (ice), hydrosphere and lithosphere
