Weight = (mass) x (acceleration of gravity where the object is).
On Earth, G = 9.8 meters/ sec² .
200 N = (mass) x (9.8)
Mass = 200/9.8 kilograms = <em>about 20.408 kg</em>. This doesn't change.
Acceleration of gravity is directly proportional to the mass of the planet, and inversely proportional to the square of the planet's radius.
So if the planet'smass quadruples and its diameter is multiplied by 3, then
the acceleration of gravity on its surface is
(4) / (3²) = (4/9 x 9.8) m/s² .
The object's mass is still 20.408 kg. That doesn't change.
Its weight is (earthly weight) x (4) / (9) = <em>(88 and 8/9) newtons</em>.
Answer:
The answer is "Keep at least a couple of extra digits beyond those needed for determining significant figures."
Explanation:
Answer:
yes. We will have the same displacement.
Explanation:
It's in the definition of a displacement that " displacement is the change in position and if the initial and final position is same then the displacement will be zero". So in the park from starting position if we end up walking at the same position then our displacement will be zero because our initial and final positions are same.
The answer is D: the GPE goes down and the KE goes up
