A kitchen bench is in the shape of a segment of a circle. The segment is bounded by an arc of length 200 cm and a chord of length 160 cm. The radius of the circle is r сm and the chord subtends an angle at the centre of the circle. 200 cm 160 cm NOT TO SCALE rcm rcm (i) Show that 1602 = 2r2(1 - cos 6). (ii) Hence, or otherwise, show that 802 + 25 cos 0...
Fiqure (a) shows two wires, each carrying a current. Wire 1 consists of a circular arc of radius R 0.021 m and two radial lengths; it carries current 2.0 A in the direction indicated. Wire 2 is long and straight; it carries current i that can be varied; and it is distance R/2 from the center of the arc. The net magnetic field due to the two currents is measured at the center of curvature in the direction perpendicular to...

Your turn: Compute the volume of the volume of revolution bounded by the parametric curve (t, 1/t) for t E [1, 0o). Then use the formula we just found to find its surface area. Does this mean you have found an object that contains less paint (volume) than it takes to paint its exterior (area)? Your turn: Compute the volume of the volume of revolution bounded by the parametric curve (t, 1/t) for t E [1, 0o). Then use the...
