Part A - Practice Problem: I direction with speed 2.9 m/s. Find the position of the center of mass at this instant. Now let's apply the center-of-mass equations to a simple one-dimensional system. Suppose a 2.0 kg cat and a 3.0 kg dog are moving toward each other along the I axis, heading for a fight. At a particular instant,...

Image that you have three steel rods that appear to be identical. However, two of the three are magnetized, having a north magnetic pole and a south magnetic pole. The third rod is not magnetized. Explain how you could find out which one is not magnetized, using only the three rods.

Sound boxes for tuning forks are essentially pipes with one end open and one end closed. The energy of the vibrating fork builds up a standing pressure wave in the sound box. Some of the sound leaks out and makes the tuning fork more audible than it would be without the sound box. Design a box for a tuning fork...

A 33 kHz sound wave travels in air at v=355 m/s; what is the temperature of the air through which it travels? b) What is its velocity and wavelength? c) Two sound waves arrive at an observer; one is -30 dB quieter than the other which is at 1000 mW/m2. What is the intensity of the quieter one in mW/m2?

[50 pts) Given: A 100-MHZ TM polarized wave with an amplitude of 1 V/m is obliquely incident from air (z < 0) onto a slap of lossless, nonmagnetic material with er = 25. The angle of incidence is 40°. Find: a) Determine the angle of transmission; b) determine the reflection and transmission coefficients and c) determine expressions for the incident,...

Problem 23. A positive test charge qtest is placed at
rest equidistance between the north and south poles of two
identical bar magnets (see figure). What is the net force on the
charge from the two magnetic poles? Suppose the magnetic strength
of one of the two bar magnets is doubled, what is the net force on
the charge from...
