Lady_Fox [76]

The gravitational force acting between them is 8.25*10^-^9N

Data given;

  • M1 = 45kg
  • M2 = 11kg
  • r = 2.0m
  • G = 6.67*10^-^1^1m^3kg^-^1s^-^1

To solve this question, we need to apply gravitational force or energy formula.

<h3>Gravitational Force</h3>

This states that the force of attraction between two bodies is equal to the product of their bodies and inversely proportional to the square of their distance apart.

Mathematically;

F = \frac{GM_1M_2}{r^2} \\

let's substitute the values and solve

F = \frac{Gm_1m_2}{r^2}\\F = \frac{6.67*10^-^1^1 * 45 * 11}{2^2}\\F = 8.25*10^-^9N

The force of gravity acting between them is 8.25*10^-^9N

What do protoplanets eventually grow into?​
kow [346]

Answer:

a planet

Explanation:

If planetesimals, objects that combined to form protoplanets, were to collide head on in the early solar nebula, they would shatter to the point where they would be unable to grow into a larger size, a protoplanet. A protoplanet is a massive object that will eventually become a planet.

PLEASE HELP ASAP! What wave measurement represents how fast the disturbance of the wave is moving?
Sever21 [200]

Answer:

Wave velocity is sometimes also called the propagation velocity or propagation speed because the disturbance propagates from one location to another. Consider the periodic water wave in Figure 13.7. Its wavelength is the distance from crest to crest or from trough to trough.
