Chapter 30, Problem 18 Interactive Learning Ware 30.1 reviews the concepts that play roles in this problem. A hydrogen atom emits a photon that has momentum 0.2523 x 10-27 kg.m/s. This photon is emitted because the electron in the atom falls from a higher energy level into the n = 4 level. What is the quantum number of the level from which the electron falls? Use values of h - 6.626 X 10-34 J, C = 2.998 x 108 m/s,...

In the X-ray spectrum of the element with Z = 32, a
K? peak is observed at a wavelength of 12.34 ×
10-11 m. (a) Determine the difference
between the observed wavelength of the K? X-ray
for this element and that predicted by the Bohr model.
(b) Express this difference (the absolute value)
as a percentage of the observed wavelength.

Interactive Learning Ware 9.1 reviews the concepts that are important in this problem. A rod is lying on the top of a table. One end of the rod is hinged to the table so that the rod can rotate freely on the table top. Two forces, both parallel to the table top, act on the rod at the same place. One force is directed perpendicular to the rod and has a magnitude of 37 N. The second force has a...

Chapter 28, Problem 10 Interactive Learning Ware 28.10 reviews the concepts that play roles in this problem. The distance from earth to the center of our galaxy is about 19,000 ly (1 ly = 1 light year = 9.47 x 101 m), as measured by an earth-based observer. A spaceship is to make this journey at a speed of 0.9990c. According to a clock on board the spaceship, how long will it take to make the trip? Express your answer...

Chapter 18, Problem 35 Background pertinent to this problem is available in Interactive Learning Ware 18.3. A uniform electric field exists everywhere in the x, y plane. This electric field has a magnitude of 3200 N/C and is directed in the positive x direction. A point charge -5.7 x 10°C is placed at the origin. Find the magnitude of the net electric field at (a) X = -0.15 m, (b) x = +0.15 m, and (c) y = +0.15 m....
