SHOW WORK. Convert the following energy measurement to the unit shown. Answer the questions related to the setup and calculation for this problem. 6.21 x 102 cal to kJ Write your work on paper showing all conversion factors, unit cancellation, and final answer with proper sig figs and units. Use this work to answer the intermediate question(s). Use the three blanks to enter the value, exponent, and unit (in this order) that appears in the numerator of the cal/J conversion factor. Calculate the answer and use the three blanks to report the answer in decimal notation with proper sig figs, value, and units.
Consider the problem of hammering a nail into a board. With due reqard for the hand holding the nail, place its pointed tip on the wood and strike it with a hammer. If the wood is hard so the nail does not go in easily, you will notice that the nail gets warm, especially after several strikes. We can figure out how much its temperature will rise by connecting what we know about Newtonian mechanics with what we are learning about temperature and heat. Let the nail have a mass of 50 g and strike it with one strong hammer blow. The hammer head has a mass of 0.5 kg (that's about 1 lb, so this is a good sized carpenter's hammer). Assume the impact velocity of the hammer on the head is 13 m/s and that it stops firmly at each blow. To make a reasonable assumption about the outcome, also assume that 75% of the energy of the hammer is converted into heat after the blow. The specific heat of the steel in the nail is about 482 J kg-1 K-1 . What is the temperature increase in the nail…
