Explain how much heat energy (in joules) must be removed to effect this cooling? An iron skillet weighing 1.78 kg is heated on a stove to 165*C. Suppose the skillet is cooled to room temperature, 21*C. Where the specific heat of iron is 0.449 j.
A +26 point charge is positioned 6.1 from a similar +26 point charge. Determine how much work would be needed by an external force to move a +0.17 test charge from a point mid-way among them to a point 1.3 closer to either of the charges?
