A 10-year, 12%, $1,000 bond that pays dividends quarterly can be purchased for $900. If the bond is purchased and pays as scheduled, calculate the nominal and the effective rate of return that the purchaser receives.
Water flows down a spillway at the rate q = 15 m^3/s into a horizontal channel where v1 = 20 m/s. Determine the depth of flow in the channel y2 that will casue the hydraulic jump to occur in the channel. Determine the headloss hL in the jump.
what are reasons for difference in the coefficient of kinetic friction on horizontal surface with a hanging mass at constant velocity compared to object one on incline
a wheel barrow is used to lift a 200lb load. the lenght from the wheel axle to the center of the load is 2ft. the length from the wheel and axle to the effort is 5 ft. illustrate and annotate the lever system.
The number of teleport inquires x in a time sharing system average .2 millisecond and follows a Poisson distribution. Find the probability at least one inquiry is made during the next millisecond.
