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:
2.41 L
Explanation:
We can solve the problem by using the ideal gas equation, which can be rewritten as:

where we have:
 (initial pressure is stp pressure)
 (initial pressure is stp pressure)
 is the initial volume
 is the initial volume
 is the initial temperature (stp temperature)
 is the initial temperature (stp temperature)
 is the final pressure
 is the final pressure
 is the final volume
 is the final volume
 is the final temperature
 is the final temperature
By substituting the numbers inside the formula and solving for V2, we find the final volume:

which corresponds to 2.41 L.
 
        
             
        
        
        
Impulse = Change in momentum.  
The ball was moving with a momentum of 0.45 * 22 = 9.9  
The ball comes to rest in the receivers arm; this means the ball's final velocity = 0. So mv2 = 0.45 * 0  
The magnitude of the impact is just the change in momentum. 9.9 - (0.45 * 0) = 9.9
        
             
        
        
        
Answer:
Because they are both easy to measure (?)
