Answer:
(c) always equal to the weight of the liquid displaced.
Explanation:
Archimedes principle (also called physical law of buoyancy) states that when an object is completely or partially immersed in a fluid (liquid, e.t.c), it experiences an upthrust (or buoyant force) whose magnitude is equal to the weight of the fluid displaced by that object.
Therefore, from this principle the best option is C - always equal to the weight of the liquid displaced.
Ng seismic and translational waves we get the law of michio kaku.
Answer:
180 N
Explanation:
Use Newton's second law, F = ma.
m = 4.5 kg; a = 40 m/s/s
F = (4.5)(40) = 180 N
Answer:
Explanation:
= Velocity of one lump =
= Velocity of the other lump =
m = Mass of each lump =
The collision is perfectly inelastic as the lumps stick to each other so we have the relation
The velocity of the stuck-together lump just after the collision is .
