The correct option is this: THIS IS THE DEMONSTRATION OF BOYLE'S LAW. AS THE VOLUME INCREASES, THE PRESSURE DECREASES AND THE MARSHMALLOW WILL GROW LARGER.
Boyle's law states that the volume of a gas is inversely proportional to the pressure of the gas at constant temperature. The law explains the relationship between the volume and pressure of a gas at constant temperature.
There is no (gap) in time between the action and the reaction
hope that helps:)
According to the conservation of momentum. In this situation, the initial momentum is equal to zero.
Since,
p=mv (Momentum)
The initial velocity of the ball = 0 m/s
The initial velocity of the man = 0 m/s
Therefore,
Total Momentum = 0
Law of Conservation of momentum states that the vector sum of the final momenta must be equal to zero which means they will have the same magnitude but in opposite directions.
<span>When the ball is kicked forward along the surface with a speed 15 m/s.
</span>then the momentum will be:
p = 4 x 15 = 60 kgm/s.
Now, the momentum of the man can be calculated as:
p = 60 kgm/s
mv = 60 kgm/s
As,
mass of the man = 80kg
So,
80 × v = 60 kgm/s
v = 60÷80
v = 0.75 m/s
It is not possible to explain the interaction of the rod and pieces of paper as a gravitational interaction.
<h3>What is Gravitational interaction?</h3>
This is defined as the interaction between a particle or body resulting from their mass. This type of interaction is usually weak and occurs in all distances possible.
It is not gravitational interaction, because the rod attracts paper only against the gravitational force of the earth and there is no attraction between both bodies under a different condition.
This is therefore the reason why it is not possible to explain the interaction of the rod and pieces of paper as a gravitational interaction.
