3. A microbiologist measures the speed of a swimming bacterium. The bacterium covers a distance of 6.82 microns in 3.5 seconds. The biologist wished to compare the speed of the bacteria with other animals, but the speeds of other animals are listed in kilometers per hour. What is the speed of the bacterium in kilometers per hour? (1 micron = 1x 10-6 m) Use scientific notation and express your answer to the correct number of significant figures. You must show your work for full credit. help please

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_
