Answer:
Force is an external agency that change or tends to change the position of a body
Force is ALWAYS measured in Newtons (N)
The interior part of Jupiter and Saturn are different from each other due to difference of core and magnetic field.
<h3>How do the interiors of Jupiter and Saturn differ? </h3>
The interiors of Jupiter and Saturn differ from one another because Jupiter has a larger metallic hydrogen core as compared to Saturn. It has stronger magnetic field as compared to Saturn.
So we can conclude that the interior part of Jupiter and Saturn are different from each other due to difference of core and magnetic field.

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°
The distance traveled by the ball before hitting the ground is 7.2 m.
The given parameters:
- Angle of projection, θ = 37⁰
- Horizontal velocity, V = 20 m/s
- Height above the ground, h = 1 m
<h3>Vertical motion of a projectile;</h3>
- The vertical motion of a projectile is affected by gravity.
The time of motion of the ball is calculated as follows;
The horizontal distance traveled by the ball before hitting the ground is calculated as follows;
Thus, the distance traveled by the ball before hitting the ground is 7.2 m.
