Asurveyor is using a magnetic compass 5.6 m below a power line in which there is a steady current of 140 a. (a) what is the magnetic field in microteslas at the site of the compass due to the power line? (b) will this field interfere seriously with the compass reading? the horizontal component of earth’s magnetic field at the site is 20 µt.

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.)
