A beam of hydrogen molecules `(H_2)` is directed toward a wall, at an angle of `32^@` with the normal to the wall. Each molecule in the beam has a speed of 1.0 km/s and a mass of `3.3 xx 10^(-24)` g. The beam strikes the wall over an area of 2.0 cm?, at the rate of `4.0 xx 10^(23)` molecules per second. What is the beam's pressure on the wall?
