Solve each given part of following question:
Question: An iron boiler of mass 180 kg contains 830kg of water at19oC. A heater supplies energy at the rate of 58,000kJ/h. The specific heat of iron is 450 J/kgoC, the specific heat of water is 4186 J/kgoC, the heat of vaporization of water is 2260 kJ/kgoC. Assume that before the water reaches the boiling point, all the heat energy goes into raising the temperature of the iron or the steam, and none goes to the vaporization of water. After the water starts to boil, all the heat energy goes into boiling the water and none goes to raising the temperature of the iron or the steam.
Part I: How long does it take for the water to reach the boiling point from 19?C?
Part II: How long does it take for the water to all have changed to steam from 19?C?
Please show all work and steps so I can fully understand all concepts! Thanks.
Assume you have a coil with 4000 turns and an average diameter of 2.00 centimeter. Determine the peak-to-peak induced emf in it at 1000 Hz
A 0.66-kg metal sphere oscillates at the end of a vertical spring. As the spring stretches from0.14 to 0.25 m ( relative to its unstrained length), the speed of the sphere decreases from 6.15 to 4.55 m/s. What is the spring constant of the spring?
