If one shines a laser with wavelength = 650 nanometer through a single slit of width a = 0.04 millimeter, draw the diffraction pattern you might expect on a screen 10 meter behind slit. Determine how far apart are the minima?
An electron passes through a point 3.91 cm from a long straight wire as it moves at 33.7% of the speed of light perpendicularly toward the wire. The wire carries a current of 11.3 A. Find the magnitude of the electron\'s acceleration at that point.
A bullet of mass m=30 g or .03 kg, is fired into a wooden block of mass M=5.0 kg. The block is attached to a string of length 1.5 m. The bullet is embedded in the block, causing the block to then swing.
What is distance of a sample of blood from the rotation axis
Determine the temperature at which the resistance of atungstenwire will bethree timesits value at 20°C. Assume its coefficient of resistivity remains constant.
A thermos bottle contains coffee at 95 ºC. Assuming that minimal heat is lost out the top, that the vacuum among the two layers of the bottle inhibits conductive and convective heat transfer and that the inner glass layer is coated with silver with a..
A man and a box are at rest on a horizontal frictionless surface (similar to an ice skating rink, only less friction). Their masses are 84.8 kg and 48.6 kg, respectively. The man pushes on the box and as a result the box moves with final speed 10.4 m..
After working really hard on a hot day a third tuning fork is used with a frequency of 1053 Hz, and the distance between the 1st and 3rd standing wave created is 33.0 cm, what is the temperature of the air in this pipe
an elevator is moving upward at a constant speed of 4ms. a man standing 10m above the top of the elevator throws a ball
The oscillations of an actual spring-block system slowly reduce in amplitude and finally the system comes to a halt. What happens to the energy of the system
