The charge would be 25 because each proton has a charge of 1.
A hammer pounding a nail into a board is an example of Newton’s Third law.
Newton’s third law states that for every action there is an equal and opposite reaction. Meaning, when you hit the hammer on the board the same amount of energy that is going into the board, is going into the hammer. Causing the hammer to bounce off the board.
Hope this helps!
To solve this problem we must use the concepts related to the Law of Malus and the intensity of light. The intensity of a linearly polarized beam of light, which passes through a perfect analyzer and vertical optical axis is equivalent to:
Where,
indicates the intensity of the light before passing through the polarizer
is the resulting intensity
indicates the angle between the axis of the analyzer and the polarization axis of the incident light.
Since the light has the same intensity after the first polarizer we approach the second intensity directly so
Our values are given as :
Therefore replacing and re-arrange to find the angle we have
Therefore the angle of the second polarizer with respect to the first one is 57.1°
Answer:
In a collision, there is a force on both objects that causes an acceleration of both objects; the forces are equal in magnitude and opposite in direction. When you hit a drum with a drumstick, there is a collision. The force both objects release causes the drumstick to bounce on the drum.

Answer:
1.18
Explanation:
The flow rate of blood is proportional to the fourth power of its radius as given the Poiseuille's law.
The law is :
It is given here that the flood flow rate is been reduced to half its normal value. Therefore,
So, for the radius and , the ratios of their flow rates are :
It is given that the flow rate is reduced to half. So we have,
or
So the radius changes by a factor of 1.18
