Answer:
The source of centripetal force is the gravitational force between the planet and Sun. Gravitational force depends on the mass of the planet, mass of the Sun and distance between them.
Answer:
5 kg
Explanation:
PE = KE
mgh = KE
m (9.8 m/s²) (1 m) = 50 J
m = 5.1 kg
Rounded to one significant figure, the mass is 5 kg.
Answer:
a result stating that a body totally or partially immersed in a fluid is subject to an upward force equal in magnitude to the weight of fluid it displaces.
Explanation:
Answer: The water Cherenkov detectors in HAWC are corrugated steel tanks 4 meters high and 7.3 meters in diameter each tank contains a watertight bladder and four photomultiplier tubes
Explanation:
Answer:
there is no net force acting on the object
Explanation:
If an object is moving with a constant velocity, then by definition it has zero acceleration. So there is no net force acting on the object. The total work done on the object is thus 0 (that's not to say that there isn't work done by individual forces on the object, but the sum is 0 ).
