You may have had an opportunity to skip rope or watch someone else skip rope. If you have one rope, you can skip by yourself or you can include two friends, each friend holding one end of the rope with you skipping in the middle. In this instance, your friends represent nodes, and you an antinode. Is it possible to skip rope with three friends with two of you in the middle jumping at different times? Explain how two jumpers can be in the middle in such a way that only onc person has to jump at a time. In your explanation, refer to the terms node, antinode, and frequency.

a. is the answer because they are not shared

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.
