A1.5 wire carries a 8 a current potential difference of 89 v is applied . what is the resistance of the wire

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

Apulley with mass mp and a radius rp is attached to the ceiling, in a gravity field of 9.81 m/s2 and rotates with no friction about its pivot.

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.
