In the united states, a doll house has the scale of 1: 12 of a real house (that is, each length of the doll house is 1/12 that of the real house) and a miniature house(a doll house to fit within a doll house) has a scale of 1: 144 of a real house. suppose a real house (see the figure) has a front length, f=19.0m, a depth, d=10.5m, a height, h=5.5m, and a standard sloped roof(vertical triangular faces on the ends) of height, roof=4.0m.

1) in cubic meters, what is the volume of the doll house?

2)in cubic meters, what is the volume of the miniature house?

An object dropped from cliff falls with a constant acceleration of 10 metre per second square find its speed of two seconds after it was dropped

Use henry's law and the solubilities given below to calculate the total volume of nitrogen and oxygen gas that should bubble out of 1.7 l of water upon warming from 25 ˚c to 50 ˚c. assume that the water is initially saturated with nitrogen and oxygen gas at 25 ˚c and a total pressure of 1.0 atm. assume that the gas bubbles out at a temperature of 50 ˚c. the solubility of oxygen gas at 50 ˚c is 27.8 mg/l at an oxygen pressure of 1.00 atm. the solubility of nitrogen gas at 50 ˚c is 14.6 mg/l at a nitrogen pressure of 1.00 atm. assume that the air above the water contains an oxygen partial pressure of 0.21 atm and a nitrogen partial pressure of 0.78 atm.
