When spotting a bench press, the spotter stands with a straight back, hands under the arms of the lifter, and carefully watches the bar. This demonstrates . good technique because the form is appropriate poor technique because the back should be bent poor technique because the spotter should be moving up and down with the lifter as they lift the weight poor technique because the spotter should have their hands underneath the bar

answer: its c lololo

false br

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.
