Charge stored in a capacitor given by Q = C*V.
So, C = Q / V.
V=30V,  Q=0.003C
C = 0.0001F  or 100μF
        
             
        
        
        
Answer: 19 s
Explanation: 
The relationship between speed, distance  and time is given by:
velocity= distance/time
time= distance/velocity= 323 m/17 m/s= 19 s
 
        
             
        
        
        
Answer:
The balloon will continue to expand and eventually burst.
Explanation:
Simply, the reason for this is because the density of the atmosphere decreases gradually as you increase in altitude closer to space. This means that the air on the outside of the balloon can't provide enough pressure over the surface of the balloon in order to counteract the gas on the inside of the balloon from expanding.
