4. A beam of hydrogen molecules (H2) is incident on the surface of a wall at an angle of 55° to the normal of the wall. Each molecule in the beam has a speed of 1.0 km/s and a mass of 3.3x10-24 g. The beam strikes the wall over an area of 2.0 cm? at a rate of 1023 molecules/s. What pressure does the beam exert on the wall? Answer: 1.9x10 Pa
