Gravity/Pressure Calculation's worksheet A football player is tackled by another player and lands with a combined weight of both players on his knee. If the combined weight of the players is 2400N and the player's knee measures 0.1m by 0.1m, how much pressure is exerted on the turf when the player lands on his knee? A forestry worker accidentally strikes a pipe with the end of a pickaxe while trying to dig a hole. If the pickaxe strikes with a force of 2000N and the end of the pickaxe measures 0.02m by 0.01m. How much pressure is exerted on the pipe by the pickaxe? A skateboarder lands on all four wheels after riding a rail. If the skateboard has a weight of 900N and the area of the bottom of a single wheel is 0.0001m2, what pressure does the skateboard put on the ground?

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
