This number is known as mechanical advantage
A: false
Fusion occurs in the Sun's core, releasing energy that is transferred outward. Once in the radiative zone, gamma rays are transferred by radiation. They are converted to other types of photons, which move into the convective zone, where they are transferred by convection. Finally, energy is emitted from the photosphere.
Answer: CaF2
Explanation:
Calcium is a metal and has 2+ cation charge. While F us in group 7 with an oxidation of -1.
So. Ca²+ F- do the criss cross rule where the charge of the cation will be the subscript of the anion and vice versa. So the result is CaF2
The answer is 570 J. The kinetic energy has the formula of 1/2mV². The total work in this process W= 1/2m(V2²-V1²) = 1/2 * 15.0 * (11.5²-7.50²) = 570 J.
