Answer:
Hey mate
Your answer will be <u>5 N</u><u> </u><u>Upwards</u><u>.</u><u> </u>
I will explain this to you.
In the attachment we can see that there are two forces acting on the object from the same side. And we know that when force acts from the same direction. Then the total force
=> sum of all the forces in that particular direction.
I hope you got it :)

Answer:
m = 500 grams
Explanation:
Assuming that the fulcrum is at the midpoint of a uniform meter stick, the moments about the fulcrum must be equal and opposite.
the 200 g mass makes a moment
200(g)[20] = 4000g gm•cm
the other mass must also create a moment of the same value
m(g)[8] = 4000g
m[8] = 4000
m = 500 grams
Answer:
d. The buoyant force on the rock is constant as it sinks.
Explanation:
The sinking of an object in water can be explained by the Archimedes Principle.
The Archimedes principle states that the buoyant force on a submerged substance is equal to the water displaced by the submerging object. The buoyant force, however, does not change with depth as the substance sinks.
In the given question, when the rock moves beneath the pool, the buoyant force do not change and remains the same that is the amount of water displaced by rock remains the same.
Thus, Option-D is the correct answer.
Answer:
A) in between Earth and the sun.
Explanation:
During this phase, the dark portion of the moon is facing Earth, so the moon is not visible in the night sky.
