A chemist carefully measures the amount of heat needed to raise the temperature of a 235.0 g sample of a pure substance from -1.2 °C to 13.7 °C. The experiment shows that 487. J of heat are needed. What can the chemist report for the specific heat capacity of the substance? Be sure your answer has the correct number of significant digits. $J \cdot g^{-1} \cdot K^{-1}$ X 5 ---

Choose the correct answer below A. Brad is incorrect due to the nonexistent Law of Averages. The fact that Brad had three black spins in a row does not matter. The likelihood the next spin will be a red is about 0.47. B. Brad is correct due to the Law of Large Numbers. As the number of spins increases, the likelihood of having at least one red spin increases C. Brad is correct due to the Law of Averages The likelihood of having four black spins in a row is about 0.05 D. Brad is incorrect due to the nonexistent Law of Large Numbers. The fact that Brad had three black spins in a row does not matter. The likelihood the next spin will be a red is about 0.47.

Consider a lossless transmission line that has a characteristic impedance of 50\Omega and is 1.2m long. It is operating at 400MHz with its propagation velocity measured at $2 \cdot 10^8 m/s$. It is terminated with a load of 75\Omega. Determine the input impedance $Z_{in}$ appears to the source and an equivalent lumped circuit model for this input impedance.

Calculate the ending balance of the Overhead account for November. Pedro Morales and Associates, a CPA firm, uses job-order costing to capture the costs of its audit jobs. There were no audit jobs in process at the beginning of November. Listed below are data concerning the three audit jobs conducted during November: Koppel $780 $5,510 72 Dupont $400 $6,650 93 Rojas $250 $3,405 49 Direct materials Auditor labor costs Auditor hours Overhead costs are applied to jobs on the basis of auditor hours, and the predetermined overhead rate is $63 per auditor hour. The Koppel job is the only incomplete job at the end of November. Actual overhead for the month was $12,950.
