You are in a gym. a basketball sits on a rack next to you while you punch a bunching bag. name two action-reaction pairs tat are present in this function.

1). Here in first case a basket ball is placed on the rack

so here force of action is on the rack due to contact of ball with the rack.

This force of the ball is downwards on the rack it is given as action force on the rack.

Now the reaction force on the ball which is due to rack on the ball. This force is upwards and act as reaction force on the ball

2) When the person in the gym will hit the bag with some force then the force of the person is action force on the bag

Now the reaction force is on the person which will punch on the bag and the direction of reaction force is opposite to that of the action force that is applied on the bag

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.

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
