Scientists hypothesize that there are no dinosaurs alive today because a) an ice age froze all of the dinosaurs. b) they were killed when a large meteor hit earth. c) they could not adapt a new environment to avoid extinction. d) mammals out-competed the dinosaurs for food and living space.

Identify the forces that contribute to the centripetal force on the object in each of the following examples: a. a bicyclist moving around a flat, circular track b. a bicycle moving around a flat, circular track c. a racecar turning a corner on a steeply banked curve

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)
