In 1.0s, 5.0x10^23 nitrogen molecules strike an area of8.0cm^2 at a speed of 300m/s. What is the pressure? (mass of one nitrogen molecule = 4.68x10^-26 kg.) I believe I should use 1/2mv ^2 for the solution but the answer I keep getting is nowhere near correct. Can someone help with this?
The energy possessed by a object by virtue of its position or its configuration is called its potential energy. Concept of potential energy is valid only in conservative field.
For higher current rating application, resistance wires with extremely large cross sections are required. The necessary large cross sections are produced in the form of resistance
