Answer:
The beat frequency is 6.378 Hz.
Explanation:
Given that,
Length of wire = 10000 m
Weight = 81.34 N
Distance = 0.660 m
Tension = 52 N
Frequency = 196 Hz
We need to calculate the mass of the wire
Using formula of weight
Put the value into the formula
The mass per unit length of the wire
Put the value into the formula
We need to calculate the frequency in the wire
Using formula of frequency
Put the value into the formula
We need to calculate the beat frequency
Using formula of beat frequency
Put the value into the formula
Hence, The beat frequency is 6.378 Hz.
The kinetic energy of the object just after it starts its motion from the Earth surface is
where m is the object mass and
its initial speed.
When it reaches its maximum height, the object speed is zero and all its kinetic energy converted into gravitational potential energy, which is
where
and h is the maximum height reached by the object.
Since the energy of the object must be conserved, K=U, therefore we can write
and we can solve to find h, the maximum height:
where m is the object mass and
