Answer:
c-) both objects will reach the bottom at the same instant.
(b) decrease.
Explanation:
Although the feather is lighter than the coin, the tube where the experiment is performed is evacuated. Therefore there is no air that prevents the feather from falling freely with the same acceleration and speed as the coin.
In fact in the equations of kinematics proposed by Newton, the mass of the bodies is not taken into account, as we can see in the following equation:
where:
Vf = final velocity [m/s]
Vi = initial velocity [m/s]
g = gravity acceleration [m/s^2]
t = time [s]
Therefore the answer is C.
Gravitational pull is a function of height, as the height of the body increases, the force of gravity decreases.
According to Lenz’s law, the induced current itself creates a magnetic field to oppose the change in the external magnetic field.
Using the right hand rule, the clockwise current creates a magnetic field vertically downward.
By Lenz’s law, the created magnetic field points downward in response to...
if the external magnetic field points upward and is increasing in strength...
or points downward and is decreasing in strength.
We are told the external field is increasing in strength, so its direction must be vertically upward.

By looking at diagrams, My guess is c.

We all know the temperature gets higher as particles bounce off each other, but to slow it they have to be more spread out and moving in a slower motion which the enzymes help this process.
