**Answer:**

A. **h = 2.15 m
**

B. **
Pb' = 122 KPa
**

**Explanation:**

The computation is shown below:

a) Let us assume the depth be h

As we know that

After solving this,

**h = 2.15 m
**

**Therefore the depth of the fluid is 2.15 m
**

b)

Given that

height of the extra fluid is

h' = 0.355 m

Now let us assume the pressure at the bottom is Pb'

so, the equation would be

**
Pb' = 122 KPa
**

**Answer:**

Saturn It is most well-known for its rings.

Neptune It has the strongest winds in the solar system.

Uranus its orbit was used to predict the existence of another planet.

Jupiter It has a giant storm three times the width of Earth.

**Explanation:**

<u>Properties of different planets</u>

Saturn is the second largest planet in the solar system and it’s most well-known for its bright and beautiful rings that circle its equator. These rings are composed of numerous ice and rock particles

Neptune has the strongest winds in the solar system and the winds are known for whipping the clouds at a speed of approximately 2000 Km/h

Astronomers used the orbit of Uranus to predict the existence of Neptune in 1846.

Jupiter has an iconic Great Red Spot just off the planet’s center which is approximately 1.3 times the Earth’s diameter and its winds move at a speed approximately 425 mph.

**Answer:**

<em>**The time traveled is 1.39 hrs**</em>

**Explanation:**

Equation of Trajectory of a comet is given as

Here

- h is the specific angular momentum given as

- μ is gravitational parameter whose value is for Venus
- r_p is the perigee distance of parabolic which is 18200 km
- As the path of comet is parabolic so energy is conserved i.e

So h is given as

So for point a where r=24500 km

So for point a where r=39000 km

So as per the Barkers equation

where

where

So

So the time traveled is 1.39 hrs

Pretty much all other colors except yellow are absorbed.

**Answer:**

The answer is C either the frequency or the wave lenght of the light

**Explanation:**

The frequency determins the brightnes of a color and the wave lenght determines the spectrum
