A pumpkin is dropped off the roof of a building. The pumpkin falls for 8.3 seconds before smashing against the ground. What is the height of the building( in other words what distance did the pumpkin fall)?

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

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.
