Physics
Ehrenfest's famous Principle of Adiabatic Invariance states that the ratio of the energy of an oscillatory motion to the frequency stays constant. This principle can be demonstrated with a simple pendulum. Consider a simple pendulum executing small-amplitude oscillations. The string with negligible mass is shortened an amount Al very slowly, so that the change in amplitude from one oscillation to the next is negligible. Show that under these conditions, the ratio of the energy to the frequency remains constant.

Ответ:
20000 pounds
Explanation:
Generally 1 gallon of fuel burnt gives of 20 pounds of CO₂
Difference in the gallons of fuel burnt
The 20 mpg car burns 1000 gallons of fuel more than the 30 mpg car
The amount of CO₂ would be
The fewer pounds that the 30 mpg car would release is 20000 pounds
