A) calculate the weight change if a full tank of oxygen(m60 aluminum cylinder, 1699 liters capacity –discharge at sea level and 20 deg c) is completely emptied.(10 kg empty wt) assume ideal gas laws hold and the tank is emptied at 20 deg c sea level. b) if the initial fill pressure was 2000 psi, what was the tank volume in liters. under stpd(standard temperature-0 deg c, standard pressure-sea level, and dry) conditions 1 mole of gas occupies 22.4 liters of volume the molecular weight : oxygen-16, 2.2 lbs/kg. 760 mm hg=14.7 psi

Porque crees que el agua no podia subir mas de 10 m de altura con ese tipo de bomba

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
