Consider a bicycle wheel that initially is not rotating. A block of mass m is attached to the wheel via a string and is allowed to fall a distance h. Assume that the wheel has a moment of inertia I about its rotation axisNow consider the case that the string tied to the block is wrapped around a smaller inside axle of the wheel of radius rB . Find ωB, the angular speed of the wheel after the block has fallen a distance h, for this case. Express ωB in terms of m, g, h, rB, and I. Which of the following describes the relationship between ωA and ωB?Which of the following describes the relationship between and ?ωA>ωBωB>ωAωA=ωB

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
