1. Each year at a college, there is a tradition of having a hoop rolling competition. Alex rolls his 0.25
kg hoop down the course. If the hoop has a radius of 0.5 m, what is the moment of inertia of
Alexs rolling hoop?
m = 0.25 kg
r = 0.5 m
I = mr2
1. What is the unit of measure of current?
The Ampere (Amp)
2. What was the original term for the battery?
3. Who invented the incandescent light bulb?
Thomas Edison and Sir Joseph Wilson Swan
4. Who invented the fluorescent light bulb?
1. Do waves transport the energy of disturbances? Explain.
Yes, because waves respond to disturbances by radiating energy outwards from the
source of the disturbance.
2. Fill in the blank: The number of wave cycles in a given unit of time is called the wa

use this fact to score a goal only using positive charges? Explain for both the practice charge and
more difficult levels.
As I brought the positive cha

1. A whistle you use to call your hunting dog has a frequency of 21 kHz, but your dog is ignoring
it. You suspect the whistle may not be working, but you can't hear sounds above 20 kHz. To
test it, you ask a friend to blow the whistle and hop on his moped
1. How does a cell phone use radiation to function?
Cell phones use radiation to carry messages and calls and the radiation transmission
occurs between your phone and the cell towers and is at maximum power when a
phone call is initiated and the handshake
1. A gas occupies 0.60 m3 at a 5.0 atm. If the temperature of the gas remains the same and the
pressure decreases to 2.5 atm, what would be the new volume occupied by the gas?
P1 = 5.0 atm
V1 = 0.60 m3
P2 = 2.5 atm
V2 = ?
P1V1 = P2V2
V2 = P1V1/P2
V2 = (5.

Range vs. Angle
Test how the angle can affect the range and determine the farthest range the object can go.
Examining the relationship between launch angles and range and understanding why that is.
1. What does the Large Hadron Collider do?
It accelerates particles by sending out two beams of hadrons to hurtle around the ring
extremely fast and with high energies to collide.
2. Describe the structure of the Large Hadron Collider.
It's a 27km long, r
1. What are the theoretical properties of a gas at a temperature of 0 Kelvin?
Theoretically, the gas would have a volume of zero and molecular m
1. A 25 N object requires a 5.0 N to start moving over a horizontal surface. What is the coefficient
of static friction?
FN = 25 N
Ff = 5.0 N
Ff = FN
2. A 12 N cart is moving on a horizontal surface with a coefficient of
1. The Washington Monument is 555 feet tall.
A. If 1 meter = 3.28 feet, what is the height of the Washington Monument in meters?
1 m = 3.28 f
Monument = 555 f
Height in meters = f/m
H = 555f/3.28m
H = 169.207 m
H = 169.0 m
