Physics
A vehicle accelerates from 0 to 30 m/s in 10 seconds on a straight road, then travels 15 seconds at a constant velocity. Next it slows down, coming to a stop in 5 seconds. The car waits 10 seconds, and then backs up for 5 seconds accelerating from 0 to -10 m/s. Draw a graph showing the vehicle's velocity vs time by following these steps. What is the velocity of the vehicle at 0 seconds? 0 m/s Click or tap the graph to plot this point.

Ответ:
Divide the amount of heat energy provided to the substance, in joules, by the mass of the substance, in grams (g). For example, if 4,000 joules of energy were provided to 500 g of water, you would calculate 4,000/500 = 8. Divide the result of the previous calculation by the specific heat capacity of the substance.
