A coffee cup heater and a lamp are connected in parallel to thesame 120 V outlet. Together, they use a total of 80 W of power. Theresistance of the heater is 5.00 102 . Find the resistance of thelamp.

A lamp is placed 1 m from a screen. Between the lamp and the screenis placed a converging lens of focal length 24 cm. The filament ofthe lamp can be imaged on the screen. As the lens position isvaried with respect to the lamp
-no sharp image will be seen for any lens position.
-a sharp image will be seen when the lens is halfway between thelamp and the screen.
-a sharp image will be seen when the lens is 40 cm from thelamp.
-a sharp image will be seen when the lens is 60 cm from thelamp.
-a sharp image will be seen when the lens is either 40 cm from thelamp or 60 cm from the lamp, but not otherwise.
