What's the formula

Does anything special happen at the supersonic-sonic boundary (reduced damage capability maybe?)

Simplify the expression.

1. 3/ sqrt 2
2. sqrt 5(6sqrt2-sqrt5)
3. 4/sqrt20

Solve the equation.
4. sqrt3x-6=0

Please read ALL the article before posting an answer. For those who believe that the thermodynamique law on energy preservation works for everything, READ the steorn.com website informations before saying its not possible. Actually the will start a live feed on 4 webcams tonight showing the system in action.
This discovery can be compared to when humans first harness fire, this could revolutionized our society and the world if politicians and oil companies (corporations in general) step out of the way to make it happen...

Could anybody please help me as to what the working out would be to answer this question? Thanks in advance:

A hedgehog wishes to cross a road without being run over. He observes the angle of elevation of a lamp post on the other side of the road to be 27 from the edge of the road and 15 from a point 10m back from the road. How wide is the road? If he can run 1m/s, how long will he take to cross?


Thanks

me and a friend are having a debate in our physics class as to whether or not grass would turn blue when an appropriate speed is reached due to the doppler effect. we worked out the mathematical point at which this would occur (cant remember exact number right now, but practically speaking the speed is beyond anything currently possible). but if this speed was attainable would grass appear to turn blue?....
