Answer:
The number of interference fringes is
Explanation:
From the question we are told that
The wavelength is
The distance of separation is
The order of maxima is m = 5
The condition for constructive interference is
=>
=>
So at
=>
Greater energy makes fast-moving water a greater force of erosion.
Answer:
Explanation:
Newton's second law of motion is F = ma, or force is equal to mass times acceleration.
( can u give me brainlist plz)
Answer:
k = 52.2 N / m
Explanation:
For this exercise we are going to use the conservation of mechanical energy.
Starting point. When it is 30 m high
Em₀ = K + U = ½ m v² + m g h
Final point. Right when you hit the water
= K_{e} = ½ k x²
in this case the distance the bungee is stretched is 30 m
x = h
as they indicate that there are no losses, energy is conserved
Em₀ = Em_{f}
½ m v² + m g h = ½ k h²
k =
let's calculate
k =
k = 52.2 N / m
1.uniti m/s indicate it is in SI unit
2.It gives the distance covered by the object in unit time
3.Unit indicates that it velocity not other unit
4.In a problem if other units are other than SI unit you can convert it
5.For comparison purpose you should know the unit unless you can't or it may be wrong
i think so
