Two lamps x and y are hanged at a distance 12 ft between their centers, Lamp x gives 140 cp and 7 ft above the working space while lamp y gives 200 cp and 5 ft above the working space. At what distance from a point directly below lamp x on the line joining their centers will the two lamps give equal amount of illumination

When the voltage source is turned off in a simple circuit consists of a resistor and an inductor, the rate of decrease of the current is proportional to the current. The current is 40 amperes at the moment that the switch is off and dies down to 15 amperes after 0.01 sec. Determine the current in 0.02 sec. 3.375 amperes 4.25 amperes 5.625 amperes 6.025 amperes
You desire to add a solar heating system to your swimming pool to extend the length of time you can use the pool. For maximum efficiency, the collector should be placed on an angle that will permit the suns rays to strike the collector at a 90 angle (Figure 14-24). When the sun is at its highest point of the day, you place a yardstick perpendicular to a flat concrete surface. The stick casts a shadow 3.5 ft long. At what angle with respect to the ground should the solar collector be placed? FIGURE 14-24 The suns rays should strike the face of the solar collector at a 90 angle.
