A0.200 kg block of a substance requires 3.59 kj of heat to raise its temperature by 20.0 k. what is the specific heat of the substance? a. 2,020 j/(kg * k) b. 383 j/(kg*k) c. 130 j/(kg * k) d. 897 j/(kg*k)

i would think form in reponse to tensional forces

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.
