Afree particle has kinetic energy equal to 35ev a)- what is the velocity of the particle? b)- if this velocity is known to within 0.2% accuracy, what is r of the position that particle? assume that the mass of the particle is 2 x 10^-26 kg. use h and give the answer in nm.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
