a metal of length 15.04cm is heated until its temperature rises by 65°c. if its new length is 16.00m calculate its linear expansivity

Calculate the amount of heat produced when 18000 coulombs of charge is transferred in one hour through a potential difference of 50v

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.)

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?
