(A) We have given wavelength of light
We have to find frequency corresponding to this wavelength
We know that velocity of light is equal to
(b) We have given frequency of vibration
We have to find wavelength corresponding to this frequency
We know that velocity of light is equal to
Answer:
FT = 103.15 N and T = 1.75 s
Explanation:
There are 3 forces at play here: gravity acting in vertical direction, tension from the string that makes 18 degrees with the vertical, and centripetal force generated by the circular motion which is horizontal.
Since the bob is moving at the constant speed, according to Newton 's 1st law the net force is 0. To find the tension force that makes a fixed angle of 18 degrees with the vertical, we can calculate that tension in the vertical direction and balance it with gravity force. Let g = 9.81m/s2
To calculate the centripetal force in the horizontal direction, we can calculate tension in the horizontal direction and balance it with the centripetal force
The centripetal acceleration a is
The radius of circular motion is:
The angular speed is
The time it would take to sweep 1 period, or 2π rad is
