Answer:
Explanation:
The equation or formula for velocity is similar to speed. To figure out velocity, you divide the distance by the time it takes to travel that same distance, then you add your direction to it.
Explanation:
There are two forces acting upon the book. One force - the Earth's gravitational pull - exerts a downward force. The other force - the push of the table on the book (sometimes referred to as a normal force) - pushes upward on the book.
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:
Explanation:
Given
Person on earth can jump to a height 
initial velocity is u
using

where v=final velocity
u=initial velocity
a=acceleration
s=displacement
final velocity is zero


On moon surface acceleration due to gravity is \frac{1}{6}[/tex] th of earth gravity
so height attained is given by

divide 1 and 2 we get
The answer is liquefaction.
This is a phenomenon that occurs when soil saturated in water or unconsolidated soil becomes a suspension because of an earthquake. The earthquake reduces the strength and stiffness of the soil. The vibrations from the earthquake and water pressure cause the soil particles to loosen.
