Find the total electric charge of 1.7 kg of electrons. me=9.11×10−31kg, e=1.60×10−19c.

The force will determine the acceleration.

On a day when the barometer reads 75.23 cm, a reaction vessel holds 250 ml of ideal gas at 20 celsius. an oil manometer ( ρ= 810 kg/m^3) reads the pressure in the vessel to be 41 cm of oil and below atmospheric pressure. what volume will the gas occupy under s.t.p.?

What causes the formation of ocean currents?
