The technician connects the lamp to a 6 V motorcycle battery instead of the 12 V car battery. He expects the current to be 400 mA (exactly ½ of the current 800 in the 12 V circuit). He measures the current and finds that it is not 400 mA. Explain why the current is not 400 mA.

Three charge are arranged as shown in the diagram. the magnitude of the net electrical force acting on the +6 uc charge, rounded to the tenths place, is .

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.)

In an experiment, how can i change human errors? be specific.
