1. A hydrogen atom initially in its ground state absorbs a photon and ends up in the n=6 state. Calculate the energy of the incident photon.
2. If the above atom in the n=6 state eventually returns to the ground state (n=1), calculate the energy of the emitted photon.
A rigid, well insulated container contains 10 kg of water. A motor connected to a paddle wheel is used to stir the water at a rate of 100 rad/s. How much toque does the motor need to supply (in N-m) in order for the water to heat up by 10?C in one..
A 1210-N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end.
If a block of wood floating on a pool of water has a volume of 37 cm3anddisplaces a volume of waterof 30 cm3, what is the densityof the wood
A gas bubble with an initial volume of 7.00 milliliters rises from a depth of meters. If the temperature does not change, what is its volume, to nearest ml, when it reaches the surface (density of water=1000 kg/m^3)?
At this point, person doing the laundry opens the lid, and a safety switch turns off the washer. The tub smoothly slows to rest in 11-s. Through how many revolutions does the tub turn while it is in motion.
His arm is 70 cm long and has a mass of 4.0 kg. Illustrate what is the magnitude of the torque about his shoulder if he holds his arm straight out to his side, parallel to the floor?
At time t = 0, the hockey puck is sent sliding over a frozen lake, directly into a strong wind. Gives the velocity v of the puck versus time as puck moves along a single axis. (The time axis is marked in increments of 0.25 s.) At t = 2.8 s, what i..
If the patch is 78 meters wide and the average force of air resistance on the skier is 179 newtons, explain how fast is she going after crossing the patch?
At a certain time an object's position was observed to be 10 meters due west. 4 seconds later the position was observed to be 5 meters due east
the axes of two polarizers make a 71.3 deg angle to one another. what fraction of the light intensity is transmitted
Consider an angular motion. If the displacement is given as 250teθ, and the radius r is constant, derive the expressions for the angular velocity θ=ω, angular accelerationα, linear displacements, linear velocitytv, normal accelerationna, and tange..
Jeff of the Jungle swings on a 7.6- vine that initially makes an angle of 47 with the vertical. If Jeff starts at rest and has a mass of 88 , illustrate what is the tension in the vine at the lowest point of the swing?
