Quiz Answer Key and Fun Facts

1. We're looking for the current of a circuit, given the voltage and resistance. What law (out of the choices) would be the best to get an immediate answer?

Answer: Ohm's Law

One of the go-to methods for circuit analysis, Ohm's Law lets us calculate resistance, voltage, and/or current of a simple circuit given two out of the three values. More advanced methods (such as Kirchhoff's Laws) would be needed for more advanced circuits.

2. We're looking for the force of something, given the mass and acceleration, and/or the gravitational constant. What law (out of the choices) would be the best to get an immediate answer?

Answer: Newton's Second Law

One of the most famous laws in science, Newton's Second Law is shown as F=ma; force equals mass times acceleration. If we know the mass and it is falling down, gravity is the only force acting upon it. Since the force of gravity is represented as a constant (9.81 m/s^2), the actual force can be attained.

Answer: Ideal Gas Law

Ideal Gas Law: PV = nRT. The special constant is known as the Universal Gas Constant. (The Boltzmann constant can also be used, but the formula changes).

Answer: Mariotte's Law

Mariotte's Law is another term for Boyle's Law. (products of pressure and volume of both gases should be the same). It is a derivation of the Combined Gas Law, and this derivation was named after physicist and chemist Robert Boyle.

5. If we were given the volume of two gases, and temperature of one of them, we can use Gay-Lussac's Law to find the fourth quantity.

Answer: False

Actually, we'd have to use Charles' Law. If we had pressure instead of temperature, we could use Gay-Lussac's law.

6. Allen Ginsberg coined this scientific law as: "You can't win". What exactly is it?

Answer: 1st Law of Thermodynamics

"You can't win" was coined by Allen Ginsberg to describe the 1st Law of Thermodynamics: Energy can't be created or destroyed. If we refer to thermodynamics as a poker game, one can't create more energy to "win" or destroy another source of energy to "win"; all energy is conserved.

7. Using a special constant, the charge of one point source, and an arbitrary distance, one can find which of these?

Answer: Electric field

Electric fields around a point source radiate equally outward, and are usually the same, depending on the distance. While this formula does not have a specific founder, this is a combination of Coulomb's Law, and Faraday's Law to depict this field.

8. The Second Law of Thermodynamics only deals with one value. What is it?

Answer: Entropy

The Second Law of Thermodynamics: "Entropy (or the general disorder) of an environment always increases or remains constant if no work is done". This only takes place in a closed system. While no work can be done to increase entropy, work must be done to decrease the entropy, or "restore order".

9. Einstein's famous mass-energy equivalence involves both mass and energy, but both are related via what quantity squared?

Answer: The speed of light

E=mc^2 was the first formula to relate the speed of light to both mass and energy. According to Einstein, this allowed mass and energy to be "different manifestations of the same thing."

10. Given a force and a specified distance, what general activity can we calculate?

Answer: Work

Coined by French mathematician Gaspard Coriolis, W=Fd calculates the specified amount of work done, or the change in energy from one point to another. Work can also be represented by the change in energy, as shown by the Work-Energy Theorem, which can be performed via algebra or via calculus.
