Answer:
m = 3.9 [m³]
Explanation:
We must remember that the density of the substance is defined as the relationship between mass over volume. That is expressed in the following equation:
where:
Ro = density = 1.3 [kg/m³]
m = mass [kg]
V = volume = 3 [m³]
Now replacing the values.
![m =Ro*V\\m = 1.3*3\\\\m=3.9[m^{3}]](https://tex.z-dn.net/?f=m%20%3DRo%2AV%5C%5Cm%20%3D%201.3%2A3%5C%5C%5C%5Cm%3D3.9%5Bm%5E%7B3%7D%5D)
For this
specific problem, the maximum value for d is 52m. I am hoping
that this answer has satisfied your query about and it will be able to help

Answer:
In Newton's Cradle there are N number of balls are suspended from the thread such that they all touch each other.
Now when we pull one ball apart and released then after the collision one ball on the other side moves up
Then in next time if we pull two balls from one side then after collision it will pull upwards exactly two balls on the other side after collision.
So here the number of balls on the other side is exactly same every time we pull the balls.
This is due to the conservation of momentum principle
As we know that all the balls are identical here then when we pull any number of balls on one side and then release them then after collision the momentum of the balls is transferred to same amount of the balls on the other side
Since there is no external force on this system so we can say that that this momentum conservation will exist for all cases and all number.

Answer:
Explanation:
We know that:
where 
is the initial energy, 
is the final energy and 
is the energy lost due to friction.
so:
Where M is the mass and V is the velocity of the runner, so:
