A stock person at the local grocery store has a job consisting of the following five segments:.1) picking up boxes of tomatoes from the stockroom floor2)accelerating to a comfortable speed.3) Carring the boxes to the tomato display at constant speed.4)decelerating to a stop.5) lowering the boxes slowly to the floor. During which of the five segments of the job does the stock person do positive work on the boxes?A) (2) and (3)B) (1) and (2)C) (1) onlyD) (1), (2), (4) and (5)E) (1) and (5)

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

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.
