If mechanical energy is converted to thermal energy, then the spring would not compress as far as it would otherwise. This will cause the spring constant to be lower than it really is. a. True
b. False

False.

Explanation:

Given that if mechanical energy is converted to thermal energy, then the spring would not compress as far as it would otherwise. This will cause the spring constant to be lower than it really is.

This statement is false. Because if mechanical energy is converted to thermal energy, there will be distortions in the solid pattern of the spring. And this will make the spring to compress.

Also, no matter what may happen to the spring, the spring constant remains constant. That is, unchanged.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
