Answer:
43850.49112 kg
Explanation:
M = Mass of moon = ![7.36\times 10^{22}\ kg](https://tex.z-dn.net/?f=7.36%5Ctimes%2010%5E%7B22%7D%5C%20kg)
r = Distance from Moon's center = ![5.23\times 10^6\ m](https://tex.z-dn.net/?f=5.23%5Ctimes%2010%5E6%5C%20m)
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
m = Mass of black hole
F = Force = 7870 N
From the universal force of gravity we have
![F=\frac{GMm}{r^2}\\\Rightarrow m=\frac{Fr^2}{GM}\\\Rightarrow m=\frac{7870\times (5.23\times 10^6)^2}{6.67\times 10^{-11}\times 7.36\times 10^{22}}\\\Rightarrow m=43850.49112\ kg](https://tex.z-dn.net/?f=F%3D%5Cfrac%7BGMm%7D%7Br%5E2%7D%5C%5C%5CRightarrow%20m%3D%5Cfrac%7BFr%5E2%7D%7BGM%7D%5C%5C%5CRightarrow%20m%3D%5Cfrac%7B7870%5Ctimes%20%285.23%5Ctimes%2010%5E6%29%5E2%7D%7B6.67%5Ctimes%2010%5E%7B-11%7D%5Ctimes%207.36%5Ctimes%2010%5E%7B22%7D%7D%5C%5C%5CRightarrow%20m%3D43850.49112%5C%20kg)
The mass of the mini black hole is 43850.49112 kg
The proof that the earth is rotating is the happens of night and day also the seasons, eg. winter, summer, autumn.
The answer is that it showed the scientist that on the area of the mantle from the subduction zones the slabs of the ocean floor remains or returns after such tectonic movement or earthquakes.
The Gamma Rays are the strongest. This would be located near the core of the sun. What makes ocean water the warmest depends on the season we are in. This is all due to the energy input into the sun.
The unit of power is called Watts.
1 way to calculate power is to divide Energy (in joules) by Time (in seconds)
Convert 4kJ to J by multiplying 4x1000
J = 4000
W = E/t
W = 4000J / 0.5s
W = 8000
Electro produced 8000 watts.
