Suppose you have two identical containers with the samevolume, both submersed in a hot water bath so that both containersare at the same temperature. One container is filledwith one mol of hydrogen gas (H2) while the other holds one mole of nitrogen gas (N2). What can you conclude about thepressures in the two containers? Of course, nitrogenmolecules are more massive than hydrogen molecules. How can that difference be understood in light of your conclusion about the pressures?
A particle with a charge of q = -5.10 nC is moving in a uniform magnetic field of vec{B}=( -1.24 T ) hat{z}. The magnetic force on particle is measured to be vec{F}= ( -7.60×10-7 N )hat{y}.
If an average frequency emitted by a 200,-,rm W light bulb is 5.00 times 10^{14} , {rm Hz}, and 10.0 percent of the input power is emitted as visible light, approximately how many visible-light photons are emitted per second .
