at a pressure of 100 kpa, a sample of a gas has a volume of 50 liters. what pressure does it exert when the gas is compressed to 40 liters

Apulley with mass mp and a radius rp is attached to the ceiling, in a gravity field of 9.81 m/s2 and rotates with no friction about its pivot.

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)

What is the weight of a feather (mass = 0.0001 kg) that floats through earth's and the moon's atmospheres?
