Explanation:

<h2>
Answer: 1.252</h2>
Explanation:
We are given this equation and we need to find the value of
:
(1)
Firstly, we have to clear
:
(2)
Applying<u> Natural Logarithm</u> on both sides of the equation (2):
(3)
(4)
According to the Natural Logarithm rules
, so (4) can be written as:
(5)
Finally:
Answer:

Explanation:
The root mean square velocity of the gas at an equilibrium temperature is given by the following formula:

where,
v = root mean square velocity of molecules:
R = Universal Gas Constant
T = Equilibrium Temperature
M = Molecular Mass of the Gas
Therefore,
For T = T₁ :

For T = T₂ :

Since both speeds are given to be equal. Therefore, comparing both equations, we get:

a.) the belief that stars and planets revolve around the earth
Explanation:
The geocentric model of stars and planets is the belief that stars and planets revolves around the earth.
The model places the earth at the center of the system.
- Geo - earth ; centric - center
- This was the original school of thought about the way the earth relates to other bodies in the universe.
- This model was replaced by the heliocentric universe in which stars are at the center and the planets revolves round them.
- The idea was put forward by Nicola Copernicus
