Consider a one-dimensional random walk, on each step of which the state moves randomly to the left or to the right with equal probability. Show that after T steps of size , the state is likely to have moved only a distan ...
In a stripping process for the removal of TCA from wastewater (very dilute, 50 mg TCA/L), air is bubbled into the water to transfer the TCA from the liquid phase to the gas phase. This process is carried out at 20°C and ...
A juniper-wood plank measuring 0.32 ft by 1 ft by 12 ft is totally submerged in water. (a) What is its weight? (b) What is the buoyant force acting on it? (c) What is the size and the direction of the net force on it?
The air in a factory is being filtered so that the quantity of a pollutant, P (in mg/liter), is decreasing according to the function P = P0e-kt, where t is time in hours. If 10% of the pollution is removed in the first f ...
A certain substance has a mass per mole of 48.0 g/mol. When 341 J is added as heat to a 30.0 g sample, the sample's temperature rises from 23.0°C to 48.0°C. What are the (a) specific heat and (b) molar specific heat of t ...
In a car lift is used in service station, compressed air exerts a force on a small piston that has a circular cross section and radius of 5cm. This pressure is transmitted by a liquid to a piston that has a radius of 15c ...
