The key to making a concise mathematical definition of escape velocity is to consider the energy. If an object is launched at it

s escape velocity, what is the total mechanical energy E_total of the object at a very large (i.e., infinite) distance from the planet Follow the usual convention and take the gravitational potential energy to be zero at very large distances. Consider the motion of an object between a point close to the planet and a point very far from the planet. Indicate whether the following statements are true or false. 1. Angular momentum about the center of the planet is conserved. a. trueb. false2. Total mechanical energy is conserved.a. trueb. false

Heating gas to create plasma can yield?
leva [86]
When a gas is heated to become a plasma, the atoms (or the molecules) of the gas become ionised. In the ionisation, the atoms loose electrons from the exterior energy levels and thus heating to achieve a plasma will create free electrons and ionized atoms (or ionized molecules).

A plasma can not contain neutrons, because neutrons together with protons make the nuclei of the atoms. To free the neutrons from the atomn nuclei there would be necessary HUGE temperatures.

Also a plasma does not contain neutral elements (atoms) or (neutral) molecules, but Ionized atoms and/or molecules and free electrons.

Thus the good answer is d)
