Looking that following diagram of bar magnets, determine if the magnets will or will not connect (attract) and why.

they will connect because the different poles are facing each other, and different poles attract.

they will not connect because like poles are facing each other, and like poles repel each other.

they will connect because the like poles are facing each other, and like poles attract.

they will not connect because different poles are facing each other, and different poles repel each other.

They will NOT connect because like poles are facing each other, and like poles repel each other.

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

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.
