Now, select the Slits simulation at the bottom of the screen, and Light (red) for the type of wave, as before. Also, make sure there is a barrier with one slit, and use the tape measure as well as the slider bar below the slit to place it roughly 1290 nm away from the light source. Adjust the slit width to 300 nm. Finally, select the start button at the source location to begin producing the waves. Which statement best describes how the intensity of the wave depends on position along the screen?

Na food processing facility, a spherical container of inner radius r1 5 40 cm, outer radius r2 5 41 cm, and ther- mal conductivity k 5 1.5 w/m · k is used to store hot water and to keep it at 100°c at all times. to accomplish this, the outer surface of the container is wrapped with a 800-w electric strip heater and then insulated. the temperature of the inner surface of the container is observed to be nearly 120°c at all times. as- suming 10 percent of the heat generated in the heater is lost through the insulation, (a) express the differential equation and the boundary conditions for steady one-dimensional heat conduction through the container, (b) obtain a relation for the variation of temperature in the container material by solving the differential equation, and (c) evaluate the outer surface tempera- ture of the container. also determine how much water at 100°c this tank can supply steadily if the cold water enters at 20°c.

This is the number of complete movements of a wave per second.
