Answer:
due to the effect of gravity begins thermonuclear fusion processes, in these processes energy is released in the form of electromagnetic radiation
Explanation:
The Sun is a star of great size, which due to the effect of gravity begins thermonuclear fusion processes, in these processes energy is released in the form of electromagnetic radiation.
This radiation crosses the different layers of the Sun and escapes from it in the form of light that is emitted throughout the radiation spectrum, due to the temperature reached by the Sun about 5500K the most likely radiation is around 5500 nm corresponding to the green- yellow of the visible spectrum, but the entire spectrum is emitted with different intensity according to Stefan's law
In quantum mechanics this spectrum can also be analyzed as the emission of particles called photons, where each one is characterized by an energy and has a moment equal to zero, the energy of these photons is related to their frequency by the Planck equation
E = h f
Let's look at the equation for momentum (p)
Where p is the momentum, m is the mass and v is the velocity.
If an object doubles in mass then we have 2m and so:
If it doubles in mass, then the momentum is also doubled.

Answer:
h = r- R with r = ∛ (G M T² / 4π²)
Explanation:
As the satellite interacts with the Earth, let's use the law of universal gravitation
F = G m M / r²
Let's write Newton's second law
F = m a
a = v2 / r
G m M / r² = m v² / r
G M / r = v²
r = G M / v²
Let's work on satellite speed, counting speed, so we use uniform speed expressions
v = d / t
Let's look for the distance it travels in a complete orbit and its time is equal to one (1) day since the satellite is geosynchronous
d = 2π r
t = T = 1 day (24h / 1day) (3600s / 1h) = 86400 s
v = 2 π R / T
Let's calculate
r = G M (T / 2π r)²
r = G M T² / 4π² r²
r³ = G M T² / 4π²
r = ∛ (G M T² / 4π²)
This distance (r) is measured from the center of the earth, let's get the height (h) from the planet's surface
r = R + h
h = r- R
