A.Equal amounts of heat are added to two different objects at the same initial temperature: 0.5 kg. of copper and 1.0 kg. of aluminum. What is the ratio of the temperature change of the aluminum object to the temperature change of the copper object? ( specific heat of aluminum is 0.220 kcal/kg. C.)

( specific heat of copper is 0.0932 kcal/kg. C )

B. How much heat is required to boil 0.5 kg. of ice initially at 0⁰ C?

C. A charge of +3 coulombs is at the origin. When charge Q is placed at 2 meters along the positive x axis, the electric field at 2 meters along the negative x axis becomes zero. What is the value of Q?

An experiment in which 44.00kJ of heat is added to a cube of metal with initial side length 1.00m and temperature 300.K is performed twice, once with a copper cube and once with a lead cube. Fill in the blanks with "<", ">", "=", "N/A". Select N/A only if a comparison is not possible. The copper cube's initial volume is the lead cube's. The copper cube's initial temperature is the lead cube's. The copper cube's final temperature is the lead cube's. The copper...

If the size and shape of two objects A & B are the same, but object B has a smaller mass: (a) for which object would the beta factor be larger? Justify your answer. (b) Which object would have a larger terminal velocity? Justify your answer. (c) Using a-b: if you dropped styrofoam ball and a steel ball of the same size/shape off a tall building, which would land land first, discounting air resistance? How about including air resistance? beta=...

Two identical balls are launched with the same initial speed, but at different angles with respect to the horizontal. They both land at the level they were launched from, and they have the same range (they travel the same horizontal distance). The maximum height reached by one ball is exactly twice as high as the maximum height reached by the other ball. The two launch angles are closest to which of these pairs? (the answer is 55 and 35). Can...

During laser-tissue interaction, heat is generated. Heat produced will increase the temperature of the tissue. Different temperature stages will give different tissue reaction. Typically, the temperature ranges can be grouped into various stages. Describe the reactions of skin tissues for the following stage: 42 - 45 °C, 50 - 60 °C, and Above 100 °C

Ice (mass=26.9 g) with an initial temperature of -15.8 oC is added to 181.4 g of water at 27.2oC in an isolated calorimeter. The mass of the aluminum calorimeter cup and stirrer together is 51.6 g. Using the values for specific heat and the nominal value of Lfice given in your laboratory manual, determine temperature of the system when it reaches equillibrium (Tf).

To one liter of water at an initial temperature of 20℃ is added 200 gm of ice at -5℃.

To one liter of water at an initial temperature of 20℃ is added 200 gm of ice at -5℃. Determine the final equilibrium temperature of the mixture, assuming the water/ice system is thermally isolated from its environment.
