The height of the roof is <u>3.57m</u>
Let the drops fall at a rate of 1 drop per t seconds. The first drop takes 5t seconds to reach the ground. The second drop takes 4t seconds to reach the bottom of the 1.00 m window, while the 3rd drop takes 3t s to reach the top of the window.
Calculate the distances traveled by the second and the third drops s₂ and s₃, which start from rest from the roof of the building.
The length of the window s is given by,
The first drop is at the bottom and it takes 5t seconds to reach down.
The height of the roof h is the distance traveled by the first drop and is given by,
the height of the roof is 3.57 m
A body accelerates due to net force acting on it. As newton's second law of motion states:
when a net force acts on a body, it produces acceleration in the body in the direction of the net force
Answer:
correct option is B
the absolute pressure will be less than 2p
Explanation:
given data
absolute pressure = p
depth = twice
to find out
what is correct option
solution
we know here that p absolute pressure so we consider atmospheric pressure p1
so we can say at some depth h pressure will be
pressure p = p1 + ρ g h
so if depth is double
pressure will be
2p = 2p1 +2 (ρ g h )
so
2p - p1 = p1 + 2 (ρ g h )
so correct option is B
the absolute pressure will be less than 2p
Animal rights<span> is the idea that some, or all, </span>non-human animals<span> are entitled to the possession of their own lives and that their most basic interests—such as the need to avoid </span>suffering—should be afforded the same consideration as similar interests of human beings. <span>They maintain that animals should no longer be viewed as property or used as food, clothing, research subjects, entertainment, or beasts of burden.</span>
