Answer:

Explanation:

Newton's second law of motion states that the rate of change of momentum is proportional to the applied force and it takes place in the direction of the force

I.e

F ∝ rate of change of momentum

Momentum is given as p =mv

F ∝ (mv-mu) / t

Let k be constant of proportion

F =k (mv-mu)/t

F= km(v-u)/t

We know that,

a = ∆V/t = (v-u)/t

Then,

F = kma

The unit of force is chosen so that k=1.

Then, F=ma

So, rearranging this will give as

a = F/m

If we assume that F is constant

Then, a ∝ 1/m

So, acceleration is inversely proportional to mass

The right option is b.

Bumek [7]

Answer:

Gravitational force is the force of attraction on a body by earth. Example - Leaves and fruits fall from a tree downwards towards the ground due to the gravitational pull. ... T-shirt for is basically the force Of attraction On a body And this force of attraction on the body is by Earth.

Intermolecular forces act between molecules. ... Intermolecular forces are weaker than intramolecular forces. Examples of intermolecular forces include the London dispersion force, dipole-dipole interaction, ion-dipole interaction, and van der Waals forces.

Rainbow [258]

Answer:

I assume they want answer A, but it's a silly question.

Explanation:

Well, if we assume that the girls are applying equal force, as they are the same size and strength (apparently also the same resolve etc.).

Equal force in opposite directions means the composite force is null. An object that no force is applied to continues moving in the same direction, so if the doll was moving somewhere, it would keep doing so, except all of this makes no sense the doll is not in gravityless vacuum what are we even talking about.

The answer A is the least ridiculous.
