A well insulated rigid vessel also contains 3 kg of saturated liquid water at 40 oC. The vessel also contains an electrical resistor that draws 10 amperes when 50 volts are applied. Determine the final temperature in the vessel after the resistance has been operating for 20 minutes.
A partial record of a freely falling body showed only 3 consecutive points. The distance from the first to the second point was 24.550 cm. that from the first to the third was 58.92 cm.
Mary is driving her car at 48 km/h. She approaches an intersection just as the traffic light turns yellow. The yellow light lasts only 3.0 s before turning to red, and she is 30 m away from the near side of the intersection.
