A2.55-m-long rod, as measured in its rest frame, speeds by you longitudinally at 6.11ã10^7. you measure its length as it passes. by how many millimeters do you determine the rod has contracted?

Determine the age of a fossil if it had only one eighth of its original carbon-14 content remaining?

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.)
