Answer:
The period of rotation is 
T=8.025s
Explanation:
The person is undergoing simple harmonic motion on the wheel 
Given data 
mass of the person =75kg
Radius of wheel r=16m
Velocity =8.25m/s
The oscillating period of simple harmonic motion is given as 
T=(2*pi)/2=2*pi √r/g
Assuming that g=9.81m/s
Substituting our data into the expression we have 
T=2*3.142 √ 16/9.81
T=6.284*1.277
T=8.025s
 
        
             
        
        
        
Answer: 
Explanation:
Given
Charge discharged 
time taken 
Current is given as rate of change of discharge i.e.

Therefore, the average current is 
 
        
             
        
        
        
It is an example of balanced force.
hope this helps. good luck
