- Find the ratio of the diameter of silver to iron wire, if they have the same resistance per unit length (as they might in household wiring). d Ag = 2.51 dFe ×arrow_forwardShow that the units 1 v2/Q = 1 W, as implied by the equation P = V²/R. Starting with the equation P = V²/R, we can get an expression for a watt in terms of voltage and resistance. The units for voltage, V, are equivalent to [? v2 v2 A, are equivalent to J/C ✓ X . Therefore, 1 = 1 = 1 A V1 J/s Ω V-A X = 1 W. . The units for resistance, Q, are equivalent to ? The units for current,arrow_forwardPlease solve and answer the question correctly please.

Jerry loves the idea of dressing up like a cat all day and of course the chance of meeting Cat Woman! On Jerry's first "job" he figures out his escape plan. He travels 3.0 km south for 15 minutes and then 8.0 km west for 1.5 hours before reaching his house. Draw a sketch diagram of the path he took with all the appropriate labels.arrow_forwardPlease solve and answer all parts of the question correctly please. Thank you!!arrow_forward
