Answer:
The height of the Everest mountain is, x = 8514.087 m
Explanation:
Given data,
The gravitational field strength at the top of mount Everest, gₓ = 9.772 m/s²
The formula for gravitational field strength is,
<em> gₓ = GM/(R+x)²</em>
Where, x is the height from the surface of the Earth
Therefore,
(R+x)² = GM/gₓ
x = √(GM/gₓ) - R
Substituting the values,
x = √(6.67408 x 10⁻¹¹ X 5.972 x 10²⁴ / 9.772) - 6.378 x 10⁶
x = 8514.087 m
Therefore, the height of the Everest mountain is, x = 8514.087 m
<span>The correct answer is option B. i.e UV Rays. The Ultra violet light is the part of electromagnetic light whose wavelength is less than the Visible light light. i.e. UV range is from 10 nm to 400 nm. UV light is invisible to the naked eye.</span>
Answer:
The mass of Neptune is 
kilograms.
Explanation:
From Newton's Law of Gravitation, the gravitational acceleration of Neptune is determined by the following formula:
(1)
Where:
- Gravitational constant, measured in cubic meters per kilogram-square second.
- Mass of the planet, measured in kilograms.
- Radius of the planet, measured in meters.
- Gravitational acceleration, measured in meters per square second.
If we know that 
, 
and 
, then the mass of Neptune is:
The mass of Neptune is kilograms.
Answer:
Bonds have been broken that held particles in place
Explanation:
Boiling took place with use of thermal energy(heat energy), this will make particles to move faster and apart from each other bcos temperature is increased. Increase in temperature causes increase in kinetic energy
Answer: There are seven main stores of energy: magnetic
internal (thermal)
chemical
kinetic
electrostatic
elastic potential
gravitational potential
Explanation: So you can have any of these
