Part F Turn off the second drip and then add a barrier with one sit. What do you observe on the right side of the wall? What do you
observe on the left side of the wall From a physics perspective, explain your observations of what is happening on both

.) the observation by semmelweis that more mothers died of childbed fever when their doctors also worked in the morgue

object 2 because all the other ones are wrong

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.
