A 1800 kg trick airplane is 450 m in the air. At this point the plane takes a dive with an initial speed of
42 m/s and accelerates to 64 m/s, dropping a total
distance of 120 m.

What is the total work done on the plane during
its dive?

The experiments with static charges were done by:

Which statement is true? a. kepler's laws apply only to the motion of earth. b. kepler's laws can be used to predict eclipses. c. kepler's laws are true for a central force that is directly proportional to distance. d. kepler's laws can be deduced from newton's laws of motion and gravity.

Estimate the change in the gibbs energy and molar gibbs energy of 1.0dm3 of octane when the pressure acting on it is increased from 1.0 atm to 100 atm. the mass density of octane is 0.703 g cm−3
