Answer: Mechanical energy

Explanation:

Mechanical energy of a body can be defined as the sum of potential energy and kinetic energy of a system.

The conservation of mechanical energy states that the sum of kinetic energy and potential energy in a system remains constant.

The only condition is the forces acting on it should be conservative forces.

Example: Running of a dog. It is its mechanical energy that is allowing a dog to run by the combination of kinetic and potential energy.

The period 4 alkaline-earth metal has the name_______ . An isotope of this element having 20 neutrons has amass numberof _______
Cerrena [4.2K]

Answer:

The period 4 alkaline-earth metal has the name Calcium. An isotope of this element having 20 neutrons has a mass number of 40.

Explanation:

Looking at the periodic table 4th row for the alkaline-earth metal, we can find Calcium which has an atomic number of 20 (or protons number, or z). The mass number is given by the sum of protons and neutrons. If the number of protons in this case is 20 and the number of neutrons is also 20, the mass number A = 40.
