Hi. Can someone please help me with this conceptual question? Consider a circuit consisting of a light bulb and an inductor. If the frequency of the generator is increased, does the intensity of the light bulb increase, decrease, or stay the same? Explain. Thank you.
The illumination at a point is inversely proportional to the square of the distance of the point from the light source and directly proportional to the intensity of the light source. If two light sources are 30 feet apart and their intensities are 70 and 50 respectively, at what point will the sum of their illumination be minimu
Suppose you were interested in determining the effect of lighting on the morale of your employees. How would you go about obtaining data for your research? What would be your dependent and independent variables? How would you determine the ideal amount of lighting? Please use a real life situation, like an Insurance office
If the sound intensity of a brass band is 2.5x10^-2 W/m^2, what is the sound level of the band?
The volume control on a stereo amplifier is adjusted so the sound intensity level increases from 23 to 61 dB. What is the ratio of the final sound intensity to the original sound intensity?
