The apparent depth of an object at the bottom of a tank filled with a liquid of refractive index 1.3 is 7.7 cm. What is the actual depth of the liquid in the tank?
REFRACTIVE INDEX = 1.3
APPARENT DEPTH = 7.7 cm
REAL DEPTH OF THE OBJECT.
Refractive Index = 1.3
Apparent Depth = 7.7 cm
Putting the values in the formula:-
The interaction of light that distorted the image of where Bill's goggles appear to be is Refraction.
<h3>
What happens to the speed of light when it hits water in a swimming pool?</h3>
The light slows down when it passes from the less dense air into the water, this slow down of the ray of light which causes the ray of light to change direction and then the changes the speed of the light that causes refraction.
The swimming pool appears shallow than it appear to be because the rays of light coming from the bottom of the swimming pool that is refracted by the water making the height of the swimming pool to be above the actual swimming pool bed and there by misleading the observer(Bill).

The mass of the star of the distant solar system is 82 * 10²² kg and the mass of the planet of the distant solar system is 8.58 * 10²⁵ kg
The planet stays in its orbit and moves in a centripetal motion due to the gravitational force of attraction between the planet and the star.
Fc = m v² / r
Fg = G M m / r²
Fc = Fg
m v² / r = G M m / r²
v² = G M / r
M = r v² / G
g = Acceleration due to gravity
G = Gravitational constant
M = Mass of star
r = Distance between both bodies
G = 6.67 * 10⁻¹¹ N m² / kg²
r = 8.6 * 10¹¹ m
T = 402 days = 3.47 * 10⁷ s
v = 2 π r / T
v = 2 * 3.14 * 8.6 * 10¹¹ / 3.47 * 10⁷
v = 15.56 * 10⁴ m / s
Ms = 8.6 * 10¹¹ * 15.56 * 10⁴ / ( 6.67 * 10⁻¹¹ )
Ms = 20.1 * 10²⁶ kg
F = G M m / r²
F = m g
Equating,
m g = G M m / r²
Mp = g r² / G
Mp = 63.6 * ( 1.8 * 10⁷ / 2 )² / 6.67 * 10⁻¹¹
Mp = 8.58 * 10²⁵ kg

It isn't best to wear loose fitting clothing when exercising, as you may not feel too comfortable. It depends on the person. However there are a few advantages.
• Tight clothing may not be comfortable as well
• Looser clothing allows easy evaporation of sweat
Then again when it says " loose - fitting " it may mean not too baggy. Baggy clothing can have an impact on your physical activity.
Answer:
The hot coffee has a higher temperature, but not a greater internal energy. Although the iceberg has less internal energy per mass, its enormously greater mass gives it a greater total energy than that in the small cup of coffee.
Explanation:
