Q)
(chatquestion)...2. The mass of a hydrogen molecule is 3.32x10 kg. If 10ª hydrogen molecules strike, per
second, a fixed wall of area 2 cm at an angle of 45° to the normal, and rebound elastically
with a speed of 10' mis, then the pressure on the wall is nearly:
(1) 2.35×10° N/m
2) 4.70×10° N/m²
3) 2.35x10'N/m²
4) 4.70x10'N/m²
