The Big Bang
The size of the Universe before the big bang
What is infinitely small (or a singularity)
The first element to form in the universe after the big bang
What is Hydrogen
These two elements are the primary elements involved in nuclear fusion in stars
What are Hydrogen and Helium
The process of combining two lighter atoms into one heavier atom when subjected to high pressure
What is nuclear fusion
Given 1mL = 1cm3, and 1000mL = 1L, convert 3.5L of water to cm3
(3.5L)(1000mL/1L)(1cm^3/1mL)3 = 3,500cm3
The composition of the universe the instant after the big bang
Superheated energy
The amount of time that passed between the big bang and the formation of the first atoms
What is 400,000 years (+/- a few thousand acceptable)
The heaviest element in the periodic table which can be produced by nuclear fusion in stars
The process in the universe that forms elements heavier than Iron
What are neutron star mergers (or other extreme cosmic events)
You work for a candy company that is moving from Miami to Toronto Canada and must switch to metric. You currently sell cubic yards of fruit by the foot, and a typical batch is 100 yd3. Convert this to liters given that 1 yd = 3 ft and 1 inch = 2.54cm
100yd3 x (3ft3 / 1yd3)3 x (12 in3 / 1ft3)3 x (2.54cm3 / 1in3)3 x (1mL / 1cm3) x (1L/1000mL) = 76455 L
This scientist, who found significant evidence in support of the Big Bang Theory, had a telescope named after him
Who is Edwin Hubble
The force which caused hydrogen atoms to coalesce into clouds which would eventually form the first stars
What is gravity
The amount of time that passed between the big bang and the formation of the first stars
About 300 million years
The force that caused quarks in the early universe to bond into hydrogen atoms
What is the strong nuclear force
The base unit for position is meters, or (m). The base unit for speed is meters per second or (m/s). The base unit for acceleration is meters per second per second, or (x). What is x?
m/s/s --> m/s/s/1 --> (m/s)(1/s) = m/s2
