Question

question 13

the ancient greek were the first to describe the electrons and protons that are found in atoms.

true
false

question 14

an example of a non-renewable resource is:

coal
forest
the oceans waves
corn

question 15

an example of electrical energy is:

a rollercoaster sitting on the top of a hill
the unbalanced forces of electrons and protons
energy stored in wood
wheels on a wagon

Explanation:

Analyze Question 13

The statement claims that Ancient Greeks were the first to describe electrons and protons. While Democritus proposed the concept of indivisible "atoms" (atomos), subatomic particles like protons and electrons were discovered in the late 19th and early 20th centuries (by J.J. Thomson and Ernest Rutherford). Thus, the statement is false.

Analyze Question 14

A non-renewable resource is depleted with use and cannot be replenished on a human timescale. Coal is a fossil fuel formed over millions of years, making it non-renewable. Forests, waves, and corn are renewable.

Analyze Question 15

Electrical energy is associated with the movement or forces between charged particles (electrons and protons). The option "the unbalanced forces of electrons and protons" represents this electrical interaction.

Answer:
