Answer:
In the absence of external forces and at any point, the sum of the kinetic energy and the potential energy is always constant.
Explanation:
Conservation of energy just means that the total energy is unchanged.
Energy is made up of potential and kinetic, so if the total is unchanged, that means the sum of them is unchanged
It would be 7 M 4 m x 2 m equals 8 M - 1 =7
Answer:
A jar of mixed nuts is the correct answer.
Explanation:
A heterogeneous mixture is a type of mixture that is not uniform in the appearance and composition varies throughout.
The heterogeneous mixture consists of multiple phases.
A jar of mixed nuts is an example of the heterogeneous mixture because they do not have a uniform composition component differ in proportion and they do not mix, instead, they form two different layers and they can be easily separated.
Answer:
density of the ball is 3.33 g/cc
Explanation:
As we know that the density is the ratio of mass and volume
here we know that
mass = 20 g
volume = 6 cubic cm
so we will have
