This is an example of resonance - when one object vibrating at the same natural frequency of a second object forces that second object into vibrational motion. The result of resonance is always a large vibration.
Answer D. Forced vibrations, such as those between a tuning fork and a large cabinet surface, result in a much lower sound than was produced by the original vibrating body Because this statement contridicts the above statement, it is not accurate
Answer:
The angle from the vertical is 48.72°
Explanation:
Given :
Length of rope 
m
Mass of man 
Kg
Mass of car 
Kg
Velocity of car 
According to conservation law,
Potential energy of man is converted to kinetic energy of car moving,
We calculate height,
( ∵ 
)
m
This is the distance of the rope at the bottom,
So we take difference of it.
⇒ 
We can calculate angle between them,
48.72°
Therefore, the angle from the vertical is 48.72°
Answer: Wallahi i don't know
Explanation:because i don't really care
<h2>
Answer:Third</h2>
Explanation:
Newton's third law states that every action force has a equal and opposite reaction force.
Example 1:
Consider yourself hitting a wall with your hand,you are exerting a force on the wall but still you feel hurt because the wall exerts same force on your hand in opposite reaction.
Example 2:
Consider yourself standing on ground.You are exerting force on ground.But how are you able to stand on ground even if your mass is forcing you to go down?The answer is normal reaction force.The ground exerts a force on your feet which makes you to stand still.
Answer:
Explanation:
λ(x) = λo x/ L
(a) The total charge is Q.
λo = 2Q/L
(b)
Let at a distance x from the origin the charge is dq.
so, dq = (2Q/L) x/ L dx
The potential due to this small charge at a distance d to the left of origin
