Question

6.
When we fix an inflated balloon on the top of a toy car or trolley, as shown in figure. Let the air
escapes from the mouth of the balloon. We notice that
IM
I
a) air escapes from the balloon towards right, the trolley along with the balloon moves towards left
so as to conserve mass
b) air escapes from the balloon towards right, the trolley along with the balloon moves towards left
so as to conserve momentum
c) air escapes from the balloon towards left, the trolley along with the balloon moves towards right
so as to conserve mass
d) air escapes from the balloon towards left, the trolley along with the balloon moves towards right
so as to conserve momentum

Answer 1

Answer:

d is the correct option

Explanation:

Answer 2

Let the air out of the mouth of the balloon:

d) Air from left balloon to left, cart and balloon to the right in order to maintain momentum.

• The moving force is equal to, in magnitude, the weight of the air removed by the volume of the balloon.
• Therefore, if you create a vacuum in a sturdy balloon with the same volume and weight as that filled with hot air, hydrogen, or helium, it can have a huge lifting power because you would not have gas weight.
• The problem, however, is that it will be difficult to make it strong enough.
• Conservation of momentum is a great law of physics that states that the momentum of a system is constant when there is no external force at work in the system.
• It is included in Newton's First Law of Inertia Act.
• The law of energy conservation is firmly established by experimentation and can even be obtained statistically by logical assumptions that the environment is the same.
