CSET CSET Physical Sciences: Physics and Chemistry

Question 1

According to Newton's Second Law of Motion, force equals:

Accepted Answer

mass × acceleration

Answer

Newton's Second Law states F = ma, where force equals mass multiplied by acceleration.

Question 2

What is the SI unit for electric charge?

Accepted Answer

Coulomb

Answer

The coulomb (C) is the SI unit of electric charge, equal to the charge transported by one ampere in one second.

Question 3

Which type of chemical bond involves the sharing of electrons between atoms?

Accepted Answer

Covalent bond

Answer

Covalent bonds form when atoms share one or more pairs of electrons.

Question 4

What is the atomic number of an element?

Accepted Answer

The number of protons in the nucleus

Answer

The atomic number uniquely identifies an element and equals the number of protons in its nucleus.

Question 5

A wave with a higher frequency will have a:

Accepted Answer

Shorter wavelength

Answer

Frequency and wavelength are inversely proportional (v = fλ), so higher frequency means shorter wavelength at constant speed.
