The local television station's newscast runs from 11:00 to 11:30 p. m. d. A rainstorm lasts all day in Kyoto, Japan. e. Two cars crash in front of your home. f. The Perseid meteor shower is seen across the eastern coast of North America. g.

answer: he got 23

explanation:

the answer is 3.1 his answer is wrong mines is right

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.
