The burner on an electric stove has a power output of 2.0 kw. A 750 g stainless steel tea kettle is filled with 20C water and placed on the already hot burner. If it takes 3.0 minutes for the water to reach a boil, what volume of the water was in the kettle?Stainless steel is mostly iron, so you can assume its specific heat is that of iron.

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s
