A glass rod is rubbed with a silk scarf producing a charge of +3.2 × 10–9 C on the rod. (Recall that the magnitude of the proton and electron charges is 1.6 × 10–19 C.) The glass rod has:

Current 1 of 8.4 a runs for 240 seconds and then stops. current 2 is 10.5 a. how long does current 2 have to un to deliver the same amount of charge as current 1? 88.28 192 s 2016 s 21,000 s

Do you agree with scientist’s prediction about the warming of alaska and other polar regions?

Oxygen and hydrogen gas are at the same temperature t. what is the ratio of kinetic energies of oxygen molecule and hydrogen molecule if oxygen is 16 times heavier than hydrogen.
