Answer:
current I1 = current I2
Explanation:
since the wire is made up of the same material, from Kirchoff's current law sum of currents entering a particular node or segment of wire is equals to the sum of currents leaving that particular node or segment of wire
B) The beam of light will bend three times: small angle of refraction through container wall; larger angle of refraction through water; small angle passing out of a container.

Something that is not magnetic
Incandescent bulbs work by conducting an electric current along a filament made of a long, thin piece of tungsten metal. The filament must be heated to temperatures of about 2,300 degrees Celsius to glow and emit a white-hot light. But the process transforms only 5 percent to 10 percent of the electricity used into visible light. The rest is transformed into heat, which can eventually increase the temperature of a room.
CFL bulbs, on the other hand, are made of glass tubes filled with gas and a small amount of mercury. The amount is so small that an old-fashioned glass thermometer holds 100 times as much mercury as one CFL bulb. Light is emitted when mercury molecules in a CLF bulb become excited by electricity running between two electrodes at its base. The mercury emits an invisible ultraviolet light that becomes visible when it hits the white coating inside the CFL bulb.
Basically, based on how they both work, fluorescent bulbs last longer and do not release as much heat as incandescent bulbs which means it's also better for the environment.
