1. Briefly, what is science?

While an airplane is in flight, four forces act on it. Thrust is caused by the airplane's propellers pushing through the surrounding air, pulling the airplane forward. Drag is caused by the air smacking into the plane's surface, pushing it backward.

Our Sun undergoes slight orbital motion mostly due to the gravitational force exerted by Jupiter. If our solar system only contained Saturn, how would the Sun's orbital period differ?

A 2,000 kg car is moving at 15m/s when it collides with a 1200kg car sitting still. Briefly compare the impulse imparted on the 1200kg car by the 2000 kg car to the impulse on the 2000 kg car by the 1200 kg car which car under goes the greater

A car accelerates uniformly from 0 to 15m/s in 5 s. Calculate acceleration.

Which device would a sleep researcher use to monitor a sleeping person's brain waves?

An experiment is performed to obtain the value of a physical property. If the true (i. e., correct) value of the property is 50 and the measured (i. e., experimental) value is 32, the percent error of the experimental result is:

White moths were found in huge numbers in the city of Birmingham. These moths could be easily camouflaged by the trees. Because of sudden industrial development, the trees in the city were covered with soot.

What two factors determine how fast weathering occurs
