"1.) Calculate the pressure at the end of a hose if it is 3 m belowthe bottom of a bucket flled with water to a height of .25 m abovethe bottome of the bucket.
2.) Given two hydraulic cylinders connected by a 5 mm hose onemeter long. The bore diameter of cylinder one is 25 mm and the borediameter of cylinder two is 75 mm. If a force of 30N is applied tocylinder one, how much mass can cylinder two support?
3.) Given a body at 50 degrees C with a surface area of 0.15 meterssquared and an emissivity of 0.7, calculate the rate of radiantenergy leaving the body.
4.) If a bus is moving toward you at a velocity of 60 km/hr, youare moving away from it at 3 m/s, what will be the observedfrequency of its horn if it is 700 Hertz at rest? The velocity ofsound is 320 m/s.
5.) What is the beat frequency of mixing three tuning forks, one at762 hertz, one at 767 and one at 770 hertz?
6.) What is the decibel level of a sound with an intensity of 2.3 X10 w/exponent -10 w/m squared?"
