A14-year-old student slams a 13-year-old into a metal locker. a 15-year-old student spreads a cruel rumor about a classmate. based on this information, who of these students is being aggressive?

Both the 14-year old and the 15-year old

Explanation:

They seem to both be committing aggressive acts, even though one is physical and one is verbal.

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.
