Apiece of nichrome wire has a radius of 7.1 x 10-4 m. it is used in a laboratory to make a heater that dissipates 3.20×102 w of power when connected to a voltage source of 110 v. ignoring the effect of temperature on resistance, estimate the necessary length of wire.

The illuminance of a surface varies inversely with the square of its distance from the light source. if the illuminance of a surface is 120 lumens per square meter when its distance from a certain light source is 6 meters, by how many meters should the distance of the surface from the source be increased to reduce its illuminance to 30 lumens per square meter?
