who wants $50?

real simple: 4 questions

1- a pipe of diamter 1cm carreiers water flowing at 1m/s. the end of the pipe is bplugged and there is a small holeon the top as shown which is 1mm diameter. How high does the water go?
*=hole
()____________*___()

2. you're indoors, with a door 1m wide and 2.5m high. the wind blows past the door at 1 m /s. what is the net force on the door and its direction? the density of air is 1.2kh/m^3.

You look at a faucent and notice that the strema narrows as it falls. Suppose that the initial water speed is v1 and the initial area of the water faucent opening is A1. Findd the area of the water stream when it has fallen a distance H. The density of water is 1kg/liter and 1 liter is a volume of a cuber w. sides 0.1m.

4- a balooon filled w. helium (density 0.1785 g/L) see previous question for desnity of air and what a liter is). Assuming a baloon of radius 10cm and ignoring the mass of the baloon how much weight could the baloon lift?

The benefit of graduate studies is that you can hand these problems down to your undergrad students and mark them as "too trivial to waste my time on; have the answers by monday please" when you have no clue how to solve it.

guys i need this in the next 10minutes. gogogogog

do i need to raise the price here or something
