If r is the total resistance of three resistors, connected in parallel, with resistances r1, r2, r3, then 1 r = 1 r1 + 1 r2 + 1 r3 . if the resistances are measured in ohms as r1 = 100 ω, r2 = 25 ω, and r3 = 10 ω, with a possible error of 0.5% in each case, estimate the maximum error in the calculated value of r. (round your answer to three decimal places.) ω

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
