3. What is the instantaneous speed of a car after 3 seconds that is traveling at 30 m/s and accelerates at a constant rate of 10m/s??

Chemical energy is a form of energy. a. heat b. kinetic c. potential d. electromagnetic

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.

How much energy must a refrigerator absorb from 225 g of water so that the temperature of the water will drop from 35°c to 5°c
