Answer:
Explanation:
4.95s≈5s
Use equation :
h=G*t²/2
h=120m ----hight of cliff
G=9.81m/s²
t=?
-----------------------
h=G*t²/2
120m=9.81m/s²*t²/2
240m=9.81m/s²*t²
t²=240m/ 9.81m/s²
t²=24.46s
t=√24.46s²
t=4.95 s≈5s
Answer:
Fg = (G * m1 * m2) / r^2
The gravitational force is Fg/16
Explanation:
Fg = (G * m1 * m2) / (4r)^2
Fg = (G * m1 * m2) / 16r
Therefore,
Fg / 16
Since direction is part of velocity, and the object is moving in a circle, its velocity is constantly changing.
The relationship of blood flow to lung function during exercise is that the blood flow in the lungs and other parts of the body is increased when a person is exercising. ... Blood travels faster from the lungs to the different parts of the body because the heart pumps faster to the lungs.
