Answer:
Explanation:
Given that,
Speed of transverse wave, v₁ = 20 m/s
Tension in the string, T₁ = 6 N
Let T₂ is the tension required for a wave speed of 30 m/s on the same string. The speed of a transverse wave in a string is given by :
........(1)
T is the tension in the string
is mass per unit length
It is clear from equation (1) that :
So, the tension of 13.5 N is required for a wave speed of 30 m/s. Hence, this is the required solution.
Answer:
0.0316 m
Explanation:
Wok done = Energy change
Work done on the spring = Energy change of the block
Elastic Potential stored = Kinetic energy of the block
x =
x =
x = 0.0316 m
k = spring constant
m = mass of block
v = velocity of the block
x = compression of spring
