Aparallel-plate capacitor, made of two circular plates of radius r - 10 cm, is connected in series 2 with a resistor of resistance r 100 q and a battery of emf e 10 v. what is the maximum value of the magnetic field induced by the displacement current between the plates, at a distance r-5 cm from the axis of the plates while the capacitor is being charged? b) 4 x 10-7

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
