N/M squared also called a PASCAL (pa) 12 of 21 how is pressure caused ? pressure is caused by tiny particles hitting against eachother. 13 of 21 what is a menometer ? a menometer - a U shaped tube filled with liquid 14 of 21 the weight of the liquid inside a tube is measured how ? by using the formula F = P x G x A x H 15 of 21 what does the F stand for in that equation ? F = weight (in newtons) 16 of 21 what does the A stand for in that equation ? A = cross sectional area in a tube (newtons) 17 of 21 what does H stand for in that equation ? H = height difference in the liquid (cm/m squared) 18 of 21 what does the P stand for in that equation ? P = density of the liquid (kg/m cubed) 19 of 21 what does the G stand for in that equation ? G = force of gravity 20 of 21 what measures pressure ? a Barometer. 21 of 21
