He total length of the strand is l = 11.0 m, the mass of the strand is m = 6.00 g, the mass of the hanging object is m = 6.00 kg, and the pulley is a fixed a distance d = 8.00 m from the wall. you pluck the strand between the wall and the pulley and it starts to vibrate. what is the fundamental frequency (in hz) of its vibration?

20.44 Hz

Explanation:

We are given that

Length of strand=L=11 m

Mass of strand=m=6 g=   (1kg=1000g)

Mass of hanging object=M=6 kg

Distance of pulley from the wall=d=8 m

We have to find the fundamental frequency of(Hz) of its vibration.

Velocity=

Where T= Tension force

Frequency=

Substitute the values in the formula

Then, we get

Frequency=

Hence, the fundamental frequency of ist vibration=20.44 Hz

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.
