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.?

Acar of mass 800kg is moving at a speed of 2.2m/s.

The resistance of 100 w bulb is less than resistance of 40 w bulb. explain the reason.
