1. In an intense electron bombardment of the hydrogen atom, signi?cant electromagnetic radiation is pro- duced in all directions upon decay. Which emission line would you expect to be most intense? Why?
2. Why are peaks due to higher-lying excited states in the Franck-Hertz experiment not more observable?
3. As the voltage increases above 5 V in the Franck-Hertz experiment, why doesn't the current suddenly jump back up to the value it had below 5 V?
4. Using Hg gas in the Franck-Hertz experiment, approximately what range of voltages would you expect for the ?rst peak? Explain.
Through 0.21 s, a wheel rotates through an angle of 2.12 rad as a point on the periphery of the wheel moves with a constant speed of 2.62 m/s. What is the radius of the wheel?
One rod is made from lead and another from quartz. The rods are heated and experience the same change in temperature. calculate the initial length of the quartz rod
A 290kg metal box is on an incline of 29 degrees and slides down4.3 m. It is kept from accelerating by a man who is pushing back on it parallel to the incline. The effective coeff of kinetic friction is 0.40.
Suppose that a projectile which is subject to a linear resistive force is thrown vertically down with a speed Vyo which is greater than the terminal speed Vterm. Describe and explain how the velocity varies with time and make a plot of Vy against ..
A force of k is applied to an object for a small fraction of a second, t_k, less than the duration of one frame, t_f. Our simulation doesn't support applying forces for less than an entire frame, so if we wanted to simulate the effect of force k over..
A converging lens (f = 13.0 cm) is held 6.20 cm in front of a newspaper, the print size of which has a height of 2.20mm. Find (a) image distance (in cm) and (b) height (in mm) of the magnified print.
A horizontal force of magnitude 34.5 N pushes a block of mass 4.09 kg across a floor where the coefficient of kinetic friction is 0.609. During that displacement, the thermal energy of the block increases by 39.3 J. What is the increase in thermal ..
Tightening a spark plug requires a 40Nm torque. If you pull a 16cm wrench at a 700 angle (to the wrench), At what force must you pull to achieve a 40Nm torque
A boy throws a ball into an open window 10m above his shoulder at 65 degrees with the horizontal. He observes that the ball flies in horizontal. A. What is the initial speed of the ball
If a virtual image is formed 10.0 cm along the principal axis from a convex mirror of focal length -15.0 cm, how far is the object from the mirror
A 19g ball of clay is shot to the right (in the positive -direction) at 21m/s toward a 38g ball of clay at rest. The two balls of clay collide and stick together. Call this reference frame S. 1. What is the total momentum in frame S?
A speedboat starts from rest and accelerates at+1.91 m/s2 for 7.00 s. At the end of this time, the boat continues for an additional 6.00 s with an acceleration of+0.518 m/s2.
