According to Newton's Second Law of Motion, force equals:
Answer: mass × acceleration
Newton's Second Law states F = ma, where force equals mass multiplied by acceleration.
What is the SI unit for electric charge?
Answer: Coulomb
The coulomb (C) is the SI unit of electric charge, equal to the charge transported by one ampere in one second.
Which type of chemical bond involves the sharing of electrons between atoms?
Answer: Covalent bond
Covalent bonds form when atoms share one or more pairs of electrons.
What is the atomic number of an element?
Answer: The number of protons in the nucleus
The atomic number uniquely identifies an element and equals the number of protons in its nucleus.
A wave with a higher frequency will have a:
Answer: Shorter wavelength
Frequency and wavelength are inversely proportional (v = fλ), so higher frequency means shorter wavelength at constant speed.
Which of the following best describes an exothermic reaction?
Answer: A reaction that releases heat to the surroundings
Exothermic reactions release energy (heat) to the surroundings, resulting in a negative enthalpy change (ΔH < 0).
