Awire, of length l = 4.1 mm, on a circuit board carries a current of i = 1.96 μa in the j direction. a nearby circuit element generates a magnetic field in the vicinity of the wire of b = bxi + byj + bzk, where bx = 4.9 g, by = 2.3 g, and bz = 2.4 g.
a. calculate the magnitude of the magnetic field b, in gauss, in the vicinity of the wire due to the circuit element.

Atank holds 1000 gallons of water, which drains from the bottom of the tank in half an hour. the values in the table show the volume v of water remaining in the tank (in gallons) after t minutes.t(min) 5 10 15 20 25 30v(gal) 694 444 250 111 28 0(a) if p is the point (15, 250) on the graph of v, find the slopes of the secant lines pq when q is the point on the graph with t = 5, 10, 20, 25, and 30.(b) estimate the slope of the tangent line at p by averaging the slopes of two secant lines.(c) use a graph of the function to estimate the slope of the tangent line at p. (this slope represents the rate at which the water is flowing from the tank after 15 minutes.)show all steps.
