1. You discover that your iPod batteries keep dying after a few days. You think that the new 48 hour iBattery will work better. What is your NEXT step in the scientific method?

2. You wonder why your dog goes to the window every day at 5:00. Your NEXT step in the scientific method should be to do what?

number of electrons for neutral cl

no

sodium is solid at rt

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.
