Answer:
Explanation:
Assuming that h is much smaller than R, then we can say the acceleration of gravity is approximately constant.
Potential energy = Kinetic energy
mgh = 1/2 mv²
v = √(2gh)
v = √(2 (MG/R²) h)
v = √(2 MGh) / R
Answer:
9.8m/s
Explanation:
Wherever you're on the earth's surface, gravitational force remains the same and it does not matter either its a rock that's being tossed or a sheet of paper, the acceleration remains 9.8m/s only. *Condition applied=air resistance neglected
No becuase the simplified case of constant speed, use the formula:
<span>distance = speed x time</span>
Answer:
If you do this enough times, you can make an object positive or negative. Friction is one of the ways to separate charge. Have you ever had a science lab where
