a parallel combination of a resistor and an unknown resistor is connected in series with a resistor and a battery this circuit is then disassembled and the three resistors are then connected in series with each other and the same battery in both arrangements the current through the resistor is the same what is the unknown resistance

How does the image distance (di) of a convex lens compare with the image distance of a concave lens? a. the image distance of the convex lens is positive, and that of the concave lens is negative. b. both are negative for a virtual image. c. both are positive for a virtual image d. the image distance of the convex lens is negative, and that of the concave lens is positive.

What are the factors that affect the resistance of a wire?

If gases like carbon dioxide and methane make up less than 1% of the total atmosphere, why is it important for scientists to monitor changes in percentages of these gases?
