108/49 in ? 108/48 cd + ? in the equation above, what particle or type of radiation needs to be included on the right hand side in order to balance it?

a. gamma
b. positron
c. beta
d. proton
e. alpha

b) positron

Explanation:

The antiparticle or the antimatter counterpart of the electron is called positron.

The positron has an electric charge of +1 e and same mass as an electron. When a positron collides with an electron, annihilation takes place.

Below is an attachnent that further explains this

Both places are expected to have the same temperature.

Explanation:

Been located the same distance from the equator means that both places are on the same latitude.

Places on the same latitude receive approximately the same intensity of solar radiation. Other factors like closeness to the sea can affect the temperature of a particular region, but in this case, it has been stated that they are both near the sea.

Other factors like elevation affect the temperature of a region but latitudinal position is approximated to elevation in most cases.

Therefore hillside and Cordera should have the same temperature.
