A sealed 26-m3 tank is filled with 2000 moles of oxygen gas (O2) at an initial temperature of 270 K. The gas is heated to a final temperature of 460 K. The ATOMIC mass of oxygen is 16.0 g/mol, and the ideal gas constant is R = 8.314 J/mol � K = 0.0821 L �atm/mol � K. The final pressure of the gas is closest to: A) 0.31

B) 0.34

C) 0.33
D) 0.36
E) 0.29

Acharge of 8.4x10^-4 c moves at an angle of 35 degrees to a magnetic field that has a field strength of 6.7x10^-3 t. if the magnetic force is 3.5 x10 ^-2 n, how fast is the charge moving?

Crowbar of 5 metre is used to lift an object of 800 metre if the effort arm is 200cm calculate the force applied
