1. Four balloons with the same size are dropped off from the same height on boards that have different numbers of nails. In which of the cases in the balloon will be the lowest pressure? 2. p=F/S 3. I am not sure about the correct answer, but I am saying my opinion about the right answer. By knowing the pressure as the force which acts onto a surface, I am saying that the board with more nails will have the biggest amount of pressure, because there are more nails in the same surface. Please, correct me if I am wrong. Thank you for your attention.
