Question

• What is the period of vibration of an object in periodic motion if it has a frequency of 0.3Hz?

• Question 2

  0 out of 10 points

  	Frequency and period of motion are directly proportional.

• Question 3

  10 out of 10 points

  	What property of an oscillating object is the total displacement from the object’s equilibrium point?

• Question 4

  10 out of 10 points

  	A girl swings on a swing attached to a swing set frame with a 4.8 m long chain. What is the period of the girl’s motion?

• Question 5

  10 out of 10 points

  	The period of an oscillating object is the time it takes for the object to complete one repetition.

Answer 1

Question 1.

Answer: frequency f= 0.3 Hz

so time period T = 1/f = 1/0.3 = 3.333 s

so time period = 3.333 s .

Question. 2

Answer: The given statement is false.

The time period and frequency are inversely proportional to each other.

Question . 3.

Answer; The total displacement form the object's equilibrium point is called Amplitude of the oscillation.

Question. 4.

Answer: Period of girl's motion , T

where l is the length of the chain = 4.8 m

and g= acceleration due to gravity = 9.8 m/s^2 , putting these values in above equation.

so time period of the girl = 4.397 s

Question. 5.

Answer: Yes , the given statement is true.

The period of an oscillating object is the time it takes for the object to complete one repetition.
