What year was Monopoly invented and by whom?
Circa. 1904 by Elizabeth Magie
Define theory
A model (i.e., representation) that seeks to account for and explain the related facts and provide means for producing new hypotheses
A train travels 25.1 miles in 0.50 hours. Calculate the velocity of the train.
22 m/s
Define inertia
A property of all matter that causes matter to prefer its present state of motion, quantified by the variable mass.
Define acoustic energy
Energy transported by sound waves

Explain what a model is and why theories are often described as models.
Model; a simplified, conceptual representation of a complex system, object, or idea that is used to understand, describe, and predict its behavior.
Theory; a comprehensive framework that explains and predicts phenomena based on a broad set of principles.
A car starts from rest and accelerates to 45 mi/hr in 36 secs. Calculate the car's acceleration and state your answer in m/s2
0.56 m/s2
What are the formulas for accleration and gravitation?
a=f/m and f=g(m1m2/r2)
Define elastic potential energy
Energy stored in a stretched or compressed object or substance.
What year was uno invented and by whom?
Circa. 1971 by Merle Robbins
What are double-blind experiments?
A double-blind experiment is when neither the patients nor the researchers know which patients are getting the placebo and which are getting the real treatment.
An electron experiences an acceleration of 5.556x106 cm/s2 for a period of 45 ms. If the electron is initially at rest, what is its final velocity?
3680 m/s2
Consider a car with a mass of 1880 kg. How much force does it take to give this car an acceleration of 1.50 m/s2?
2,820 N
What is dark energy?
The unknown cause of the acceleration of the universe's expansion.
In a two-player game of Uno Attack, which cards take on special properties and what new cards are added?
The reverse card becomes a skip card, and there 5 new cards; Hit 2, Wild Hit 4, Discard All, Attack! Attack!, and Wild Attack-Attack.
How did Sir Humphry Davy become a hero?
He invented the Davy Safety Lamp, which used mesh to cool the flame temperature, meaning less explosions from the methane gas found in the mines being ignited with the lamps.
A proton is uniformly accelerated from rest to 80.0% of the speed of light in 18 hours, 6 minutes, 45 seconds. What is the acceleration of the proton?
48.3 ns

56.8 kg and 1.64 m/s2
What is the purpose of the Large Hadron Collider?
To accelerate protons and have them collide at extremely high energies to help scientists discover more about the fundamental structure of matter.
Explain the Kamikaze rules of CABO
When a player has acquired two 13's and two 12's, they may call Cabo and end the round. If they have successfully pulled Kamikaze, they receive a 0 on their score sheet and all other players receive 50 on their scoresheet, no matter their score.
