Calculate the minimum uncertainty in (a) the speed of a ball of mass 500 g that is known to be within 1.0 µm of a certain point on a bat, and (b) the position of a bullet of mass 5.0 g that is known to have a speed somewhere between 350.000 01 m s−1 and 350.000 00 m s−1 ?

Aregular polygon has angkes of size 150° each. how many side has the polygon

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
