Answer:

B) Scientist discover that 99% of the universe’s mass is hydrogen

Explanation:

Hydrogen and helium represent almost all nuclear matter in the current state of the universe. This is consistent with the Big Bang theory. This theory indicates that approximately 25% of the universe’s mass is helium, while hydrogen constitutes approximately 73% of the universe’s mass.

A 2010 kg space station orbits Earth at an altitude of 5.35×105 m. Find the magnitude of the force with which the space station
Shkiper50 [21]

Answer:

Force, F = 16814.95 N

Explanation:

It is given that,

Mass of space station, m = 2010 kg

Altitude, d=5.35\times 10^5\ m

Mass of earth, m=5.98\times 10^{24} kg

Mean radius of earth, r=6.37\times 10^6\ m

Magnitude of force is given by :

F=G\dfrac{Mm}{R^2}

R = r + d

R=6.37\times 10^6\ m+5.35\times 10^5\ m=6905000\ m

F=6.67\times 10^{-11}\times \dfrac{2010\ kg\times 5.98\times 10^{24} kg}{(6905000\ m)^2}

F = 16814.95 N

So, the force between the space station and the Earth is 16814.95 N. Hence, this is the required solution.
