Tectonic plates move due to _____ forces.
wel
<span>Tectonic plates move because they are floating on top of the liquid mantle. The mantle itself moves due to convection currents: hot rock rises, gives off some heat, then falls. This creates vast swirls of moving liquid rock under the crust of the earth, which jostles the plates of crust on top.

You said 0.5 · m · v² = m · g · h

Divide each side by 'm' :  0.5 · v² = g · h

Multiply each side by 2 :  v² = 2 · g · h

Square root each side :   v = √(2 · g · h)

You said that  g = 9.8 m/s²  and  h = 875 units

So  v = √(9.8 m/s² · 875 units)

v = √(8,575 m·unit/s²)

v = 92.6 / s² · √(m · unit)

The evil team of Ms. Moonstruck and Mr. Luny intend to deflect the Moon from its orbit around Earth by pulling it with a force o
BabaBlast [244]

Answer:

92867kg

Explanation:

DATA:

mass of the moon 'm_1'= 7.36 x 10^2^2kg

mass of the mini black hole 'm_2'=?

universal gravitational constant= 6.67x10^-^1^1 Nm²/kg²

distance 'r'= 7.47×10^6 m

force 'F'= 8170N

Newton's Law of Universal Gravitation is given by:

F=G\frac{m_1m_2}{r^2}

m_2=\frac{(8170)(7.47*10^6)^2}{(6.67*10^-^1^1)(7.36*10^2^2)}

m_2=92867kg
