a flare is launched from a life raft with an initial velocity of 176 m/ sec. how many seconds will it take for the flare to return to the sea?
find the speed at which water travels in a pipe if the height is (use the formula v^2 = (h+10)
a. 5cm b. 8cm. c. 18cm.
the velocity of a bloodcorpuscle in a vessel depends on how far the the corpuscle is from the center of the vessel. let r be the constant radius of the vessel ; Vm , , the constant maximum velocity of the corpuscle ; r, the distance from the center to a particular blood corpuscle (variable); and Vr, the velocity of that corpuscle . the velocity Vr, is related to the distance according to Vr=Vm(1-r^2/R^2). find r when Vr=1/4 Vm.
the sensitivity S to a drug is related to the dosage x by S=1000x-x^2. sketch the graph and determine what dosage gives maximum sensitivity. use the graph to determine the maximum sensitivity.
