Answer:
The refractive index of material of prism is 1.06.
Explanation:
Given that,
Angle of prism, A = 40 degrees
Angle of deviation,
We need to find the refractive index of material of prism. We know that the relation between angle of deviation, prism angle and the refractive index is given by :
is the refractive index of material of prism
So, the refractive index of material of prism is 1.06. Hence, this is the required solution.

Explanation:
The statement which best explains why nickel will reach the ground first is: C. The force of air resistance acts more strongly on the sheet of paper than on the nickel.
<h3>What is gravity?</h3>
Gravity can be defined as a force of attraction that controls the movement of objects and the planets such as Earth around the Sun.
<h3>The factors that affect gravity.</h3>
Some of the factors that affect the force of gravitational attraction that is acting on an object or a physical body include the following:
Generally, nickel will reach the ground first before a sheet of paper due to the effect of the force of air resistance because it would act more strongly on the sheet of paper than on the nickel.

Answer:
density I believe, air gets compressed when In pressure, so the air would have more density
Answer:
Explanation:
Using Hooke's law,
F = -kx
Where,
F = force of the mass
k = spring constant/stiffness
x = length of the spring
Given:
F1 = m1*a
= 4.1 * 9.81
= 40.221 N
F2 = m2*a
= 1.5 * 9.81
= 14.715 N
x1 = 2.9 cm
F1/x1 = F2/x2
Therefore,
x2 = (14.715 * 2.9)/40.221
= 1.06 cm.
