Because gravitational potential energy equals mass•acceleration due to gravity•height (mgh), we can calculate the potential energy by multiplying 80•9.8•8850, which results in 6,938,400 j.
Answer:
The centripetal acceleration changed by a factor of 0.5
Explanation:
Given;
first radius of the horizontal circle, r₁ = 500 m
speed of the airplane, v = 150 m/s
second radius of the airplane, r₂ = 1000 m
Centripetal acceleration is given as;

At constant speed, we will have;

a₂ = 0.5a₁
Therefore, the centripetal acceleration changed by a factor of 0.5
Answer:C
Explanation:
Given
weight of object is equal to weight of object
Suppose weight of Planck is W
suppose weight is at distance of x cm from wedge
balancing Torque



i.e. at a distance of 0.25L from the Left end
The answer would be the coulombs law.
Answer:
If the two plates are of equal density, they usually push up against each other, forming a mountain chain. If they are of unequal density, one plate usually sinks beneath the other in a subduction zone. Hope this helps!
