The rocket is fired vertically and tracked by the radar station shown. when ΞΈ reaches 66Β°, other corresponding measurements give the values r = 32700 ft, rΒ¨ = 85 ft/sec2, and ΞΈΛ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.

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 β 103 s. given that the charge of an electron is 1.6022 β 10β19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.
