Answer:
mas of water displaced = 41.4 g
Explanation:
Weight in air = True weight = 45 g
Apparent weight = 3.6 g
Apparent weight = True weight - Buoyant force
Buoyant force = 45 g - 3.6 g = 41.4 g
Weight of water displaced = Buoyant force
Weight of water displaced = 41.4 g dyne
mas of water displaced = 41.4 g
Answer:
D: Increase the distance between the objects.
E: Decrease the mass of one of the objects.
Approximately 100-120 wolves
Weightlessness is experienced when there is no net force acting on a body in the vertical direction. Whenever an object is rotating, such as the earth is, it applies an outward centrifugal force on the objects on its surface. At the equator, this force is in the direction exactly opposite to the force attracting us towards the earth, gravity.
If the earth were to spin faster by almost 17 times, the centrifugal force would become equal to the force of gravity and an object would experience weightlessness.
