While dusting a carpet we beat it with a stick because:a)Force applied on the carpet.b)No inertia is involved.c)Inertia of motion removes the dust.d)Inertia of rest keeps the dust in its position.Correct answer is option 'D'. Can you explain this answer?

Question

Answer

Because the dust particle is in rest position hence if we beat the carpet the inertia of rest will break and tey fall down .

Answer

Initially ,  the carpet and loose dust in it are in the state of rest . when the carpet is hit with a stick , it is suddenly set into motion but the loose dust in it remains in the state of rest because of inertia of rest. thus ,in a way that is left Behind relative to carpet and hence comes out in the air in fact it is the carpet which comes out of the dust.

Answer

This is because when we beat the carpet ,the dust particles on them are in state of rest. When we beat the carpet,the carpet moves away but the dust particles are in rest due to inertia of rest. Therefore as the carpet moves the dust particles fall down. Hope it helps!

Answer

The Correct Answer is Option 'D': Inertia of Rest keeps the dust in its position.

In order to understand why beating a carpet with a stick removes dust, we need to first understand the concept of inertia. Inertia is the tendency of an object to resist any change in its state of rest or motion. Objects at rest tend to stay at rest, while objects in motion tend to stay in motion.

Inertia of Rest

The concept of inertia of rest states that an object at rest will remain at rest unless acted upon by an external force. In the case of a carpet, the dust particles are initially at rest and are not easily dislodged or removed. When we beat the carpet with a stick, we apply a force to the carpet, causing it to move. However, due to the inertia of rest, the dust particles tend to resist this change in their state of rest and stay in their original positions.

Beating the Carpet

When we beat the carpet with a stick, the force applied causes the carpet to vibrate and shake. This shaking motion helps to dislodge the dust particles from their positions within the carpet fibers. The force of the stick hitting the carpet creates a disturbance, causing the dust particles to become airborne.

Effect of Inertia of Rest

The inertia of rest comes into play when the dust particles within the carpet try to resist the shaking motion and remain in their positions. Due to this inertia, the dust particles require a greater force to be dislodged from the carpet fibers. The repeated beating of the carpet helps to overcome this inertia and gradually removes the dust particles.

Conclusion

By beating a carpet with a stick, we apply a force that overcomes the inertia of rest of the dust particles. The shaking motion caused by the beating helps to dislodge the dust particles from the carpet fibers. However, it is important to note that beating the carpet alone may not completely remove all the dust particles. Vacuuming or using other cleaning methods may be necessary for a more thorough cleaning.
