Given data:
- Amount of air in balloon = 5 g
- Velocity of air escaping = 4 cm/s
- Time taken for balloon to shrink completely = 2.5 seconds
Calculating the change in momentum:
- The mass of the air escaping from the balloon can be calculated using the amount of air and the density of air.
- Density of air at room temperature is approximately 1.2 kg/m³.
- Mass of air escaping = 5 g = 0.005 kg
- Volume of air escaping = Mass / Density = 0.005 / 1.2 = 0.00417 m³
- Change in momentum = Mass x Velocity = 0.005 x 4 = 0.02 kg m/s
Calculating the average force:
- Average force = Change in momentum / Time taken = 0.02 / 2.5 = 0.008 N = 8 dyne
Therefore, the average force acting on the balloon as it shrinks completely is 8 dyne. So, the correct answer is option (c) 8 dyne.
- Amount of air in balloon = 5 g
- Velocity of air escaping = 4 cm/s
- Time taken for balloon to shrink completely = 2.5 seconds
