9) A small light fixture is on the bottom of a swimming pool,0.75 m below the surface. The lightemerging from the water forms a circle on the still water surface.What is the diameter of this circle? m
A point source of light is located 6.6 m below the surface of a large pool of water. Find the area of the largest circle on the pool's surface through which light coming directly from the source can emerge. a-
2 Underground water is to be pumped by a 80 percent efficient 10-kW submerged pump to a pool whose free surface is X m above the underground water level (see Figure 2). The diameter of the pipe is 10 cm on the intake side and 8 cm on the discharge side. Determine (a) the maximum flow rate of water and (b) the pressure difference across the pump. Assume the elevation difference between the pump inlet and the outlet and the...
4. A 2.00 C charged 1.00 g cork ball is suspended vertically on a 0.500 m long light string in the presence of a uniform downward-directed electric field of magnitude E-1.00x105 N/C. If the ball is displaced slightly from the vertical, it oscillates like a simple pendulum. (a) Determine the period of the ball's oscillation. (b) Should gravity be included in the calculation for part (a)? Explain. (15) 3. The magnetic field shown in Figure 4 directed into the paper....
I have the answers but need to see these worked out. Thanks! 11- The nickel's image in the figure has twice the diameter of the nickel when the lens is 2.84 cm from the nickel. Determine the focal length of the lens. 12- Problem 22.17: An electric catfish can generate a significant potential difference using stacks of special cells called electrocytes. Each electrocyte develops a potential difference of 110 mV. How many cells must be connected in series to give...
