5. a kettle has a power of 1200 w (hint: 1200 w = 1200 j/s). if the kettle
takes 2.5 minutes to boil water, how much energy had been transferred?

According to social exchange theory, altruistic behaviors benefit the individual who performs them. t/f

In physics the desire of an object to keep doing what it is doing is termed?

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.)
