You perform a double-slit experiment in order to measure the wavelength of the new laser that you received for your birthday. You set your slit spacing at 1.09mm and place your screen 8.51m from the slits. Then, you illuminate the slits with your new toy and find on the screen that the tenth bright fringe is 4.58cm away from the central bright fringe (counted as the zeroth bright fringe). What is your laser's wavelength λ expressed in nanometers?
A rod of proper length L moves past you a speed v. You reach out and grab the back end of the rod, bringing that point instantly to rest in your frame of reference.
A cylnder holds .5 moles of an ideal gas at temp 334K. The gas expands isothermally from an initail volume of .03 m^3 to a final volume of .4m^3

Calculate the location along the x-axis ,in m, of the ball when it reaches the bottom of the hoop.
At a particular location, the cross section of the Columbia River is as indicated in Fig. P10.43. If on a day without wind it takes 5 min to float 0.5 mi along the river, which drops 0.46 ft in that distance, determine the value of the Manning coe..
The two components of a double star are observed to move in circles of radii r1 and r2. What is the ratio of their masses?
Four identical springs support equally tghe weight of a 1300 kg car. the car driver goes over a speed bump, find the oscillation period
A locomotive is pulling 13 freight cars, each of which is loaded by roughly the same weight. The mass of each can be taken to be 37, 000 kg. If the train is accelerating at 0.42 m/s2 on a level track, what is the tension in the coupling among the sec..
Is momentum conserved in all of the experiments? Please give a complete description with examples as needed supporting your response.
An equipotential line surrounds a charge distribution of known value (35 mC). Two points A and B are selected on this equipotential line separated by 3.0 cm. What is the potential difference DV between these points
A 10 g ball of clay traveling east at 1.5m/s collides and sticks together with a 30g ball of clay traveling north at 2.5m/s. What is the speed of the resulting ball of clay
The roof of a two-story house makes an angle of 29° with the horizontal. A ball rolling down the roof rolls off the edge at a speed of 4.5 m/s. The distance to the ground from that point is 8.2 m.
