17.29---While painting the top of an antenna 230 m in height, a worker accidentally lets a 1.00-L water bottle fall from his lunchbox. The bottle lands in some bushes at ground level and does not break.
A) If a quantity of heat equal to the magnitude of the change in mechanical energy of the water goes into the water, what is its increase in temperature?
Change in energy, E = mgh = 1 x 9.8 x 230 = 2254 J
E = mc dT
dT = mgh/mc = gh/c
dT = (9.8 x 230)/4186
dT = 0.538 degree Celsius
Comment in case any doubt please rate my answer ...

1. A pole is held vertically by attaching wires at a height of 13.4 m above the ground. The other end of each wire is anchored in the ground at a distance of 9.54 m from the base of the pole. The pole makes a right angle with the ground. What is the length of each wire? 2. A bug crawls 2.25 m along the base of a wall. Upon reaching a corner, the bug's direction of travel changes from...
