The focal length of a lens is inversely proportional to the quantity (n-1), where n is the index of refraction of the lens of th

Ainat [17]

Answer:

46.22 cm

Explanation:

The focal refraction, fr is given by

$fr = \frac {c}{(1.572 -1)} = \frac {c}{0 .572}$

The focal red light is given by

$fv = \frac {c}{(1.605 - 1)} = \frac {c}{0.605}$

$\frac {fv}{fr} = \frac {0.572}{0 .605} = 0.945455$

$\frac {1}{fr} = \frac{1}{image} + \frac {1}{object}$ and making fr the subject we obtain

$fr = \frac {image * object}{(image + object)} = \frac {24.00 * 55} {(24.0 + 55)} = 16.70886 cm$

fv = 0.945455* 16.70886 cm = 15.79747 cm

$image = \frac {object * f} {(object - f)} = \frac {15.79747 * 24.0}{(24.0 - 15.79747)} = 46.22222 cm$

Therefore, violet image is approximately 46.22 cm

The gravitational acceleration on the Earth's surface is ce of a plan et with the same size, but twice the mass? it be on the A.

KengaRu [80]

Explanation:

The acceleration due to gravity is on Earth is given by :

$g_e=\dfrac{GM_e}{R^2}$ ..............(1)

Where

M is the mass of Earth

R is the radius of Earth

G is the universal gravitational constant

$g_e=32\ ft/s^2$

The formula for acceleration due to gravity on planet is given by :

$g_p=\dfrac{GM_p}{R_p^2}$ ..............(2)

Since, $M_p=2M_e$

From equation (1) and (2) :

$\dfrac{g_p}{g_e}=\dfrac{M_p}{M_e}$

$g_p=2\times g_e$

$g_p=2\times 32\ ft/s^2$

$g_p=64\ ft/s^2$

So, the acceleration on the planet is 64 feet per second square. Hence, this is the required solution.

How long does it take for rain to go back down when it evaporates up?

andriy [413]

It takes about ten days for water that has evaporated from the earth to come back.

<h3>What is evaporation?</h3>

The term evaporation has to do with the fact that a liquid molecule receives sufficient energy and is able to escape the attractive forces that binds it to the surface of the liquid and then escapes to the atmosphere.

Water is a liquid and it can fall to the earth during rainfall. When it does, it could accumulate on the earth surface and is then gradually evaporated back to the atmosphere.

It takes about ten days for water that has evaporated from the earth to come back.
