**Calculus: need clarification to where the #'s go**

When air expands adiabatically (without gaining or losing heat), its pressure P and volume V are related by the equation PV^{1.4}=C where C is a constant. Suppose that at a certain instant the volume is 330 cubic centimeters and the pressure is 79 kPa and is decreasing at a ...

A block of mass M rests on a block of mass M1 = 5.00 kg which is on a tabletop. A light string passes over a frictionless peg and connects the blocks. The coefficient of kinetic friction mk at both surfaces equals 0.330. A force of 60.0 N pulls the upper block to the left and ...

**Algebra**

The pressure of a gas varies jointly as the amount of the gas (measured in moles) and the temperature and inversely as the volume of the gas. If the pressure is 975 kPa(kiloPascals) when the number of moles is 4, the temperature is 250 K, and the volume is 320 cc, find the ...
