Answer:
it is chemical energy
Explanation:
that is the energy used by our body, so it is the one that we will loose. and the energy that we gain is also chemical energy
Since unbalanced forces acts on the spheres, the aim of increasing the release distance of the spheres is to observe the effect of unbalanced forces acting on the spheres.
<h3>What is an experiment?</h3>
An experiment is a study whose objective is to study cause and effect relationships. In this case, the students had to increase the distance at which the spheres was released.
The aim of increasing the release distance of the spheres is to observe the effect of unbalanced forces acting on the spheres.

Answer: the statement that describes the transformation of energy is statement B (The potential energy was turned into Albertine's kinetic energy, which was then converted into internal(thermal) energy.)
Explanation:
Law of conservation of energy states that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another.
Throughout Albertine's journey, no energy was lost. Her potential energy was converted to kinetic energy and then to thermal energy of the body.
Answer:
F = 1400 N
Explanation:
It is given that,
Mass of the ball, m = 70 kg
It is moving with an acceleration of 20 m/s². We need to find the force exerted by the ball.
Force is given by the product of mass and acceleration. So,
F = ma
So, the force of 1400 N is exerted by a metal ball.
