Explanation:
Archimedes' principle states that the upward buoyant force which is exerted on body when immersed whether fully submerged or partially in the fluid is equal to weight of fluid which body displaces and this force acts in upward direction at center of mass of displaced fluid.
Thus,
<u>Weight of the displaced fluid = Weight of the object - Weight of object in fluid.</u>
Answer:
F = 0.483 N
Explanation:
Initial momentum, 
Final momentum, 
Time, t = 31 s
We need to find the force of a lead ball. We can use here the impulse momentum theorem.
F is force
So, the force is 0.483 N.
You used density, because water/ice has a density of 1, and ice will sink in anything with a lesser density
Answer: A force must cause a displacement in order for work to be done. A book falls off a table and free falls to the ground. Yes. This is an example of work.
Explanation:
you could make a self propelled car all you need is cardboard, wheels, and a balloons or rubber bands
