Answer:
B
Explanation:
option b stands for less down and cm is less than km
The one in the water would have a much greater speed than the one in the air since energy is transmitted better and faster in liquid than gas.

Let's call
and
the masses of the two blocks. We can write Newton's second law for both blocks (sum of all forces acting on the block = ma). On block 1, we have two forces: the weight
pointing downwards and the tension of the string T poiting upwards. On block 2, we have the tension of the string going right and the friction
going left. Therefore
Summing the two equations, we find
and then using
we can find the acceleration:
Answer:
Lowering of mass of the shot has high kinetic energy which leads to covering more distance of the shot.
There is a difference in these throws because the mass of the shot decreases which increases its velocity and as a result the shot covers more distance. First, the athlete throws the shot having 16-pound weight or mass which covers 40 feet distance.
Whereas in the second throw, he uses a shot having 12-pound it covers 50 feet distance because the mass
is lower in the second throw and the athlete can easily throw the shot which covers more distance so the second shot has more kinetic energy as well as more velocity which compels it to cover more distance so we can conclude that lowering of mass leads to covering more distance of the shot.
