PHYSICS HESI
1. Which of these statements is true regarding the way light travels?
A) The speed of light is always the same regardless of the medium through which it
travels.
B) Light cannot travel through a vacuum.
C) Sound travels faster than light.
D) Light travels as both a wave and a particle.
Light is a curiosity in that it acts as both a wave and a particle. It only changes
direction via reflection (bouncing off of something) or refraction (passing from one
medium to another). In a vacuum, the speed of light is constant, but when passing
through a medium that has an index of refraction different from a vacuum, light’s
speed slows.
2. According to the theory of the same name, after the “Big Bang” there were only
what two things?
A) Neutrons and electrons
B) Matter and antimatter
C) Mass and gravity
D) Space and time
The Big Bang Theory attempts to explain the origins of the universe. According to
the theory, a “big bang” produced matter and antimatter in equal quantities.
3. A subatomic particle is __________ in relation to an atom.
A) Denser
B) Faster
C) Bigger
D) Smaller
Subatomic particles (which include neutrons, protons, and electrons) are much
smaller than atoms.
4. Who discovered the special theory of relativity?
A) James Chadwick
B) Alfred Nobel
C) Albert Einstein
D) Max Plank
The theory of relativity is one of physics’ most famous theories and was proposed
by Albert Einstein.
, 5. A fresh egg will float in water __________.
A) It will not float in any circumstance.
B) When salt is added to the water
C) Always
D) When the water is cold.
Eggs are typically more dense than water, which makes them sink. However, if
enough salt is added to the water, the water becomes more dense than the egg,
which will cause the egg to float.
6. How fast does sound travel through a vacuum?
A) 222 m/s
B) 331.4 m/s
C) 25 m/s
D) 0 m/s
Sound waves cannot travel through a vacuum.
7. What planet is the slowest rotating and often referred to as Earth’s “sister
planet”?
A) Mars
B) Jupiter
C) Mercury
D) Venus
Because of their similar size and distance from the sun.
8. A woman has a mass of 50kg on the moon. What is her mass on Earth?
A) 25 kg
B) 0 kg
C) 100 kg
D) 50 kg
Weight changes due to differences in gravitation force, mass remains the same.
