A2.14 kg block resting on a frictionless surface is attached to an ideal spring with spring constant k = 252 nm . the block is pushed to compress the spring by 9.08 cm from its equilibrium position. while the spring is being compressed, find (a) the work done by the spring and (b) the work done by the applied force.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
