3 A circuit is powered by a 9-volt battery, the lightbulb can only handle 1.5 amps of currently flowing
through it Ifa 4 resistor is added to the circuit, will that provide enough resistance not to break the
bulb?

Light from two different sources are incident upon the same side of a polarizing filter. light from one source is polarized with total intensity ip, while light from the other source is unpolarized with total intensity iu. as you rotate the polarizing filter through 360 degrees, the intensity of the transmitted light on the other side varies by a factor of 9. what is the relative intensity of the initial polarized source to the unpolarized source, or ip/iu?
