Hi all, I really need some help with the following question, I have to find the pressure at point B, within the manometer. height A=0.71m height B=200mm p(roh)=882 kg/m^3 p(roh)m=13784 kg/m^3 (is this the density of the gas?) Pressure at point A=156850Pa I have tried using the...

i have this question for an engineering science assignment, and can't remember how to work it out, any help would be greatly appreciated. Question: A car of mass 1500kg has a max speed of 144km/h up an incline of 1 in 49 against a frictional resistance of 500N. Calculate the power of the engine.

Hi I wonder if anyone can help, I am stuck on this question. [b]1.Two smooth spheres A and B, of masses of 300g and 700g respectively, are traveling towards each other along the same horizontal line with speeds of 8m/s and 4m/s respectively. After the collision, the direction of motion B has...
