SUMMARY
The discussion focuses on calculating the pressure exerted by a falling sand shower, where grains of sand, each with a mass of 3.10 x 10-3 g, fall from a height of 0.8 m at a rate of 50 grains per second per cm2. The pressure is determined using the formula P = F/A, where the force (F) is calculated by multiplying the mass of the grains by their velocity. The area of impact is clarified to be 1 m2, simplifying the calculation of pressure.
