Answer:
Explanation:
Basically, Kinetic Molecular Theory says that gas particles are in constant motion and that they show perfectly elastic collisions.
An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision.
So the kinetic molecular theory says that gas particles stay moving constantly and don't lose energy when they run into each other.
Hope this helps!
Answer:

Explanation:
As we know that charge is always conserved
so here we have
initial total charge = final total charge
also we know that gamma rays are chargeless and massless particles
so we have
charge on deuterium is given as
Q = charge on proton + charge on neutron - charge on gamma
so we have


Astronauts in space<span> do </span>talk<span> to each other. In the spacecraft, there is plenty of air, so they just </span>talk<span> normally.
