- oome of the planets in your model were very small. If you were to make them 10 times larger, what would happen to the size of the Sun in the model?
- 4. An instrument used to measure a specific gas pressure is a a) manometer b) barometer c) calorimeter d) thermometer 5. Which of the following represents the largest pressure? a) 1lb/in^2 b) 1Pa c) 1 atmosphere d) 1 mm Hg 6. As the altitude increases the atmospheric pressure a) stays the same c) increases b) changes randomly d) decreases 7. Which of the following statements about real gases is correct? a) Real gases deviate from Boyle's Law at low pressures. b) Real gases deviate from Boyle's Law at high pressures. c) Real gases experience significant attractive forces between the particles. d) Real gases deviate from Charles' Law at high temperatures.
- (4) 3) Select the best answer. Why are the meters squared in the formula to calculate acceleration? The seconds are squared to show exponential acceleration. The seconds are squared to show constant acceleration. The seconds are squared because velocity often has units of meters per second (m/s) and time also has units in seconds (s). The seconds are cubed not squared.
- (1) 2) Select the best answer. What is the formula to calculate acceleration? ((m)/(s^2))=(v_(i)-v_(f))/(t) ((s^2)/(m))=(v_(f)-v_(i))/(t) ((m)/(s^2))=(v_(f)-v_(i))/(t) ((s^2)/(m))=(v_(i)-v_(f))/(t)
- 1) Select the best answer. What is acceleration? the process of speeding up speed in a certain direction remaining at a steady velocity any change in velocity
