Question

9. What are the three main components of the scientific method?





10. The experimentally verified amalgamations or unifications in physics so far are

(select all that apply)

Heat and Mechanics become Statistical Mechanics

Gravity and Quantum Mechanics become Quantum Gravity

Electricity and Magnetism become Electrodynamics

Electrodynamics and the Weak Force become Electroweak theory

The Weak Force and Strong Force become Quantum Hadrodynamics

Electroweak theory and Quantum Chromodynamics become Grand Unified Theory (GUT)

GUT and Gravity become string theory or M-theory

11. Which ones of question (10) are correct descriptions of actual current theories being pursued in physics, but have not been experimentally confirmed yet?



12. In Physics before 1920, Feynman describes long-range and short-range forces. What three current physics theories would we call these now (state which theory goes with which force).

13. State which of the four fundamental forces (gravity, weak, electromagnetic (E&M), strong) are predominantly involved in the following processes:

My hand bouncing back up when I bang it against a table.

Ice melting on a hot day.

Ice freezing in the freezer.

Barbecuing hot dogs.

Flying to the moon with current conventional means.

Flying to the nearest star (not counting the sun) in just 5 years.

The gazillions of neutrinos that are flying out of the sun right now.

Whatever is going on as I type this sentence and these black letters appear :)

A pendulum clock going back and forth.

Boiling water.

Peeling out (or burning rubber) when you accelerate a car really fast.

Getting the protons in the Large Hadron Collider up to total energy 13 TeV.

Nuclear power plant moderation.
