A satellite is put into an orbit at a distance from the center of the Earth equal to twice the distance from the center of the E

arth to the surface. If the satellite had a weight at the surface of 4000 N, what is the force of gravity (weight) of the satellite when it is in its orbit? Give your answer in newtons, N.

Answer:

995 N

Explanation:

Weight of surface, w= 4000N

Gravitational constant, g, is taken as 9.81 hence mass, m of surface is W/g where W is weight of surface

m= 4000/9.81= 407.7472

Using radius of orbit of 6371km

The force of gravity of satellite in its orbit, F=\frac {GMm}{(2r)^{2}}=\frac {GMm}{4(r)^{2}}

Where G=6.67*10^{-11} and M=5.94*10^{24}

F=\frac {(6.67*10^{-11}*5.94*10^{24}*407.7472)}{4*({6.371*10^{6}m)}^{2}}

F= 995.01142 then rounded off

F=995N

How can astronomers infer approximately how long the universe has been expanding?
Jlenok [28]
Not only astronomers, but all scientists use the technique of rock dating to determine the age of the universe. From the Big Bang Theory, all the celestial bodies were made at the same time. So, the age of the Earth is just the same with the age of the universe. So, they gather rocks deep down in the crust of the Earth and let it undergo radioactive decay. By determining the amount of radioactive material left and half-life, they could compute the age of the Earth.

How is the law of acceleration applied in accomplishing a task in relation to a person's ability and the effort exerted?
ivann1987 [24]
Newton's second law of motion states that the force is equal to the product of the mass and acceleration. It can mathematically be expressed as,
                                      F  = m x a
When this equation is transformed to solve for acceleration, this becomes,
                                   a = F / m
The equation suggests that for an object to move, force has to be exerted.

MAJOR POINTS! Solve the system of equations to find <img src="https://tex.z-dn.net/?f=%20a_%7B2%7D%20%20" id="TexFormula1" title

You are dealing with pulleys?

can be done with addition of the two equations to eliminate T.

(2^{*}) \quad {} -m_1 g \cos \theta + T = m_1 a _2
+
(4^{*}) \quad 3m_1 g - T = 3m_1 a_2
=

(-m_1 g \cos\theta  +  3m_1 g) + (T - T) = m_1 a _2 + 3m_1 a_2 \implies \\ \\&#10;(-m_1 g \cos\theta  +  3m_1 g) = 4m_1 a_2 \implies \\ \\&#10;m_1(- g \cos\theta  +  3g)= 4m_1 a_2

we can cancel m₁ by dividing both sides by it, assuming mass is not zero


(- g \cos\theta + 3g)= 4a_2 \implies \\ \\&#10;a_2 = \dfrac{- g \cos\theta + 3g}{4} \\ \\&#10;a_2 = \dfrac{- 9.80  \cos 60 + 3(9.80)}{4} \\ \\&#10;a_2 = 6.125 \text{m/s}^2&#10;

a₂ = 6.125 m/s² ( do significant digits if you need to)
