Answer:
Time=8.23880597 seconds 
Explanation:
Quantity of charge(q)=2.76c
Current(I)=0.335A
Time(t)=?
t=q/I
t=2.76/0.335
t=8.23880597seconds
 
        
             
        
        
        
Answer:
Explanation:
distance of fan A = 18.3 m
distance of fan B = 127 m 
speed of sound (s) = 343 m/s
 What is the time difference between hearing the sound at the two locations?
time (T) = distance / speed
- time for sound to reach fan A = 18.3 / 343 = 0.053 s
- time it takes for sound to reach fan B = 127 / 343 = 0.370 s
- time difference = 0.370 - 0.053 = 0.317 s
 
        
             
        
        
        
Answer:
(a) Bus will traveled further a distance of 40 m 
(b) It will take 7.5 sec to stop the bus 
Explanation:
We have given initial velocity of the bus u = 24 m/sec
And final velocity v = 16 m/sec 
Distance traveled in this process s = 50 m 
From third equation of motion we know that 


(a) Now as the bus finally stops so final velocity v = 0 m/sec
So 

s= 90 m 
So further distance traveled by bus = 90-50 =40 m
(b) Now as the bus finally stops so final velocity v= 0 m/sec
Initial velocity u = 24 m/sec
Acceleration 
So time
