By Newton's Law of Universal Gravitation.
F = GMm/r²
Where F is Force of Gravitation, M = Mass of first object, m = mass of second object, r = distance of separation
From the formula, you can see that if the masses, M and m, increased, the value of F would definitely increase as well.
And if r increased the value of F would be reduced because you would be dividing by a bigger number, but when the value of r is decreased the value of F would be increased, because you would then be dividing by something smaller. Note the r is at the denominator of the formula.
So F would increase if there was increase in Masses and decrease in distance.
So the answer is C. a and b.
Answer:
Ос.
The spacing between particles increases.
Heat causes greater particle activity, and the particles
are farther apart.
Cortisol, prolactin, growth hormone and testosterone
Answer:
Explanation:
<h3>a and b</h3>
We can use the following formula, from kinematics:
where is the final speed, is the initial speed, a is the acceleration and d the distance traveled.
Knowing that the final speed is zero, and the initial speed is
we obtain
Now, knowing that
then
<h3>c</h3>
We can use the following formula
so
<h3>d</h3>
