Answer:
887.1Hz
Explanation:
Given parameters: 
Speed of sound wave  = 330m/s 
Wavelength  = 0.372m 
Unknown: 
Frequency  = ? 
Solution: 
 To solve this problem, we use the expression below: 
              Speed  = Frequency x wavelength 
             330  = Frequency x 0.372 
    Frequency  = 887.1Hz

2)240<span>°
3)759,600m or 759.6 km</span>
        
             
        
        
        
Answer:
a)
b)
c)
d)
e)
Explanation:
Given that:
- initial speed of turntable,  
- full speed of rotation,  
- time taken to reach full speed from rest,  
- final speed after the change,   
- no. of revolutions made to reach the new final speed,   
(a)
∵ 1 rev = 2π radians
∴ angular speed ω:

where N = angular speed in rpm.
putting the respective values from case 1 we've


(c)
using the equation of motion:

here α is the angular acceleration



(b)
using the equation of motion:





(d)
using equation of motion:



(e)
using the equation of motion:
