The greatest amount of inertia can be calculated by the following equation
Kinetic Energy = 0.5 x mass x (velocity)^2
You are trying to find Kinetic Energy.
KE = 0.5 x 30kg x 100
KE = 1,500
Your answer is (2) because when using the equation, the child has the greatest amount of inertia.
Answer:
A
Explanation:
density is defined to be as the mass per unit volume therefore you divid the mass by the volume
<h3>Hi!</h3>
The answer would be B. Lower.
Explanation:
This is because Force between two bodies is directly proportional to the mass of an object, but inversely proportional to the square of the distance between them.
So if the mass of the moon becomes twice, the force would also be twice as strong. (2 F ) , but if the distance is doubled, this force (2 F ) would be quartered ( 2F/4 = F/2 ) which would be half of the original force F.
Hence if the force is halved, the tides would be lower.

Answer:
The answer to your question is below
Explanation:
To explain what happens with the ball we must remember the Law of Conservation of Energy.
This law states that the energy can be neither created nor destroyed only converted from one form of energy to another.
Then,
At the top of the hill, the potential energy is maximum and the kinetic energy equals to zero.
When the ball starts to roll down the potential energy will be lower and the kinetic energy will have a low value.
At the middle of the hill, both energies have the same values.
At the end of the hill, the potential energy will be equal to zero and the kinetic energy will be maximum.
it is important so you can discover new materials or inhabitle planets in case anything happens to earth
