Atemperature-stable resistor is made by connecting a resistor made of silicon in series with one made of iron. if the required total resistance is 1300 capital omega in a wide temperature range around 20degrees celsius, what should be the resistances of the two resistors? the temperature coefficients of the resistivities for iron and silicon are: alphairon = 5.0times 10-3 k-1

Moon effect. some people believe that the moon controls their activities. if the moon moves from being directly on the opposite side of earth from you to being directly overhead, by what percentage does (a) the moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? assume that the earth–moon (center-to-center) distance is 3.82 × 10^8 m, earth's radius is 6.37 × 10^6 m, moon's mass is 7.36 × 10^22 kg, and earth's mass is 5.98 × 10^24 kg.

This is the substance(s) formed in a chemical reaction.

How are series and parallel circuits simililar? both have multiple paths for electrons to travel. both require resistors in their circuits. both require a switch to complete the circuit. both have at least one path for electrons to travel.
