    4. DTheir temperatures will remain the same as they started
  4. 4Assume C=A*B, C must be at least 65536, and A must be at least 512. Pick the value pairs for A and B to satisfy this condition.
    1. AA = 1024, B = 64

    5. EA = 2048, B = 128
    6. FA = 512, B = 16
  5. 5C = A*B. If A is multiplied by four and B is divided by eight, what is the new value for C?
    1. AOne quarter its original value
    2. BEight times smaller
    3. CTwice as large
    4. DHalf the original value
  6. 6Check all of the phrases which mean the exact same thing.
    1. AObject A is twice the mass of object B.
    2. BTwo of object A would have equal the mass of object B.
    3. CObject B is half the mass of object A.
    4. DIf object A was doubled in mass, object B would be four times less massive than A.
    5. EHalf the mass of object B is equal to one eighth the mass of object A.
    6. FObject A is 200% the mass of object B.
  7. 7Which of the following mathematical relationships grows the fastest when x > 0?
    1. AQuadratic (y=x^2)
    2. BLogarithmic (y = log[x])
    3. CExponential (y=2^x)
    4. DLinear (y = x)
    5. EReciprocal (y = 1/x)
  8. 8 Which of the following is the most likely result of dramatically heating gas in a rigid container which has no exit?
    1. APressure Explosion
    2. BNothing
    3. CNuclear Explosion
    4. DHot Gas
  9. 9If the time taken for a machine to do something reduces by 4 seconds every time the input speed is doubled, and it takes 28 seconds with an input speed of 128 rad/s, how fast must the input speed be for the time taken to be 4 seconds?
    1. A4096 rad/s
    2. B65536 rad/s
    3. C8192 rad/s
    4. D32 rad/s

    1. AIf a fair coin is flipped, and it has landed "Heads" the last eight times, it has a 50% chance of landing "Tails" the ninth time.
    2. BIf something has a 50% chance of happening, and it is given four chances to happen, it will happen exactly twice.
    3. CIf a number of marbles are randomly scattered around the floor, they will be approximately evenly spaced.
    4. DIf something has a 2% chance of happening, and it is given a chance to happen every 0.05 seconds, it will have at least a 95% chance of happening within 7.5 seconds.
    5. EA random number generator, which outputs numbers from 1 to 10 (inclusive) outputs "10" eleven times in a row. It has a very low chance (less than 1%) of outputting "10" the next time.
    6. FIt is possible for something to have a 99.99% chance of happening yet fail to do so after 400 chances.
