The two ways to write the symbols for this isotope are: 238
92 U or U-238

The model below shows two isotopes.

Compare and contrast the two isotopes. On the lines below, describe how they are the same and
different. Cite evidence from your observations that prove that these two isotopes are of the same
atom.

answer; equivalent to a one(1) horsepower motor;

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.
