A loop of wire with radius r = 0.065 m is in a magnetic field with magnitude B as shown in the figure. B changes from B1= 0.65 T to B2 = 4.5s at a constant rate. The resistance of the wire is R = 19Ω. Part (a) Calculate the numerical value of the change in magnetic flux, ΔΦ in T·m2? Part (b) Calculate the numerical value of the average emf, s, induced in the loop in volts. Part (c) Calculate the numerical...
Other answers have not been helpful. I have to drag the pointers(B1,B2,B3 etc) onto a place on the grid. A bunch of arrows doesnt help. I need to know where to place the pointers and if possible how, thanks and will upvote. The diagram below shows three current-carrying wires. All three wires carry the same current, but in different directions, as indicated. A B C D E Drag each marker to the location of the head of the corresponding magnetic...

Need help, will rate, thanks. 3. Given n 1 data pairs (xo, yo), (xi,yi),..., (^n, Jn), define for j 0, 1,...,n the functions pj - Ilifj (zj-zi), and let also ψ(x)-111-o(x-xi) (a) Show that pj-(xj) (b) Show that the interpolating polynomial of degree at most n is given by yj
Need a help with both parts pelase. I need help with b1 and b2. Thank you. Assume the return on a market index represents the common factor and all stocks in the economy have a beta of 1. Firm-specific returns all have a standard deviation of 47 % Suppose an analyst studies 20 stocks and finds that one-half have an alpha of 45 %, and one-half have an alpha of-4.5 %. The analyst then buys $1.5 million of an equally...
