Electromagnetic waves are often called "electromagnetic radiation".
That's a really strong clue.

Heat carried in the form of electromagnetic waves is radiation.

C is radiation
Convection is the transfer of heat by the flow of material (usually air or water)
Conduction is energy transferred when molecules bump into one another
Radiation is the answer

Question
The overall charge of the nucleus is _____ a. positive b. negative c. neutral
Solution 1
The overall charge of the nucleus is POSITIVE. This is because the nucleus of an atom is made up of protons and neutrons. Protons are positively charged particles while neutrons are neutrally charged particles which means it has no charge and cannot effect the protons electric charge in any way. Therefore, since the only effective charge is positive, we can conclude that the nucleus is also positive.

Question
The metallic elements which all react in water are found in the: same group same period rare earth elements
Solution 1

The metallic elements which all react to water are found in the same group,  named Alkali metals, or also known as group Ia.

What are Alkali Metals?

The six chemical elements that make up Group 1 (Ia) of the periodic table—lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr)—are together referred to as alkali metals. The name "alkali metals" refers to how they react with water to produce alkalies (i.e., strong bases capable of neutralising acids).

Due to their high level of reactivity, alkali metals are typically found in nature in combination with other elements. Simple minerals that are soluble in water are those like  sylvite (potassium chloride, KCl), halite (sodium chloride, NaCl),and carnallite (a potassium-magnesium chloride, KCl MgCl2 6H2O). However, the Earth's crust contains a much greater quantity of more complicated, water-insoluble minerals.
