Answer: 1.50
Explanation:
Given that:
C (critical angle) = 41.7°
n (index of refraction in benzene) = 2.42
n (index of refraction in benzene) = ?
To get the index of refraction in benzene, Apply the formula n = 1/sineC,
n = 1/sine41.7°
n = 1/sine 41.7°
n = (1/0.6652)
n = 1.50
Thus, the index of refraction for the ray in benzene is 1.50
Newton's third law<span> is for every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. </span>
Answer:
0.70 d
Explanation:
m1 = 97 kg
m2 = 548 kg
m = 69.7 kg
Let the distance between m1 and m2 is d .
Let m be placed at a distance s from m2 so that the net force on m is zero.
Force between m1 and m is balanced by force between m and m2
G m1 x m / (d - s)^2 = G m x m2 / s^2
m1 / (d - s )^2 = m2 / s^2
97 / (d - s)^2 = 548 / s^2
(d - s)^2 / s^2 = 97 / 548
(d - s) / s = 0.42
d - s = 0.42 s
d = 1.42 s
s = 0.70 d
