Problem: A 0.9m x 0.9m x 0.9m cube of nitrogen gas is at 15oC and 1.1 atm.
Part I: Estimate the number of molecules in the cube with a speed between 700 m/s and 1000 m/s.
Please show the work for the calculation so I can understand what I'm doing to find the number of molecules in the cube Thanks!
A 1.50-m-long bar is pulled to the right at a steady 5.0 m/s perpendicular to a uniform 0.75 T magnetic field. The bar rides on parallel metal rails linked through a 25Ωresistor R, so the apparatus makes a complete circuit. The resistance of the bar ..
