Step 1
Bahan Baku Feronikel Untuk menghasilkan 1 ton Stainless Steel dengan kandungan Ni 8%, maka diperlukan 0.08 ton Ni. Karena Feronikel memiliki kandungan Ni 18%, maka diperlukan 0.08/0.18 = 0.4444 ton Feronikel. Namun, yield Feronikel adalah 95%, sehingga diperlukan Show more…

A manufacturing company produces steel housings for electrical equipment. The main component part of the housing is a steel trough that is made out of a 14-gauge steel coil. It is produced using a 250-ton progressive punch press with a wipe-down operation, putting two 90-degree forms in the flat steel to make the trough. The distance from one side of the form to the other is critical because of weatherproofing in outdoor applications. The company requires that the width of the trough be between 8.31 inches and 8.61 inches. The following are the widths of the trough in inches for a sample of n=49: 8.312, 8.343, 8.317, 8.383, 8.348, 8.410, 8.351, 8.373, 8.481, 8.422, 8.476, 8.382, 8.484, 8.403, 8.414, 8.419, 8.385, 8.465, 8.498, 8.447, 8.436, 8.413, 8.489, 8.414, 8.481, 8.415, 8.479, 8.429, 8.458, 8.462, 8.460, 8.444, 8.429, 8.460, 8.412, 8.420, 8.410, 8.405, 8.323, 8.420, 8.396, 8.447, 8.405, 8.439, 8.411, 8.427, 8.420, 8.498, 8.409.

A parallel-plate capacitor with plates of area 25.0 cm² and 2.00 mm separation is charged to a potential difference of 250 V and disconnected from the source. The capacitor is then immersed in distilled water. Assuming the liquid is an insulator, determine (a) the capacitance before and after immersion, (b) the potential difference after immersion, and (c) the change in energy of the capacitor.

Natural uranium must be processed to produce uranium enriched in $^{235} \mathrm{U}$ for weapons and power plants. The processing yields a large quantity of nearly pure $^{238} \mathrm{U}$ as a by-product, called "depleted uranium." Because of its high mass density, $^{238} \mathrm{U}$ is used in armor-piercing artillery shells. (a) Find the edge dimension of a 70.0 -kg cube of $^{238} \mathrm{U}$ ( $\rho=$ $\left.19.1 \times 10^{3} \mathrm{kg} / \mathrm{m}^{3}\right) .$ (b) The isotope $^{238} \mathrm{U}$ has a long half-life of $4.47 \times 10^{9} \mathrm{yr} .$ As soon as one nucleus decays, a relatively rapid series of 14 steps begins that together constitute the net reaction $$^{235}_{92} \mathrm{U} \rightarrow 8\left(^{4}_{2} \mathrm{He}\right)+6\left(_{-1}^{0} \mathrm{e}\right)+_{82}^{206} \mathrm{Pb}+6 \bar{\nu}+Q_{\text {net }}$$ Find the net decay energy. (Refer to Table A.3.) (c) Argue that a radioactive sample with decay rate $R$ and decay energy $Q$ has power output $P=Q R$ (d) Consider an artillery shell with a jacket of $70.0 \mathrm{kg}$ of $^{238} \mathrm{U}$. Find its power output due to the radioactivity of the uranium and its daughters. Assume the shell is old enough that the daughters have reached steady-state amounts. Express the power in joules per year. (e) What If? A 17 -year-old soldier of mass $70.0 \mathrm{kg}$ works in an arsenal where many such artillery shells are stored. Assume his radiation exposure is limited to absorbing $45.5 \mathrm{mJ}$ per year per kilogram of body mass. Find the net rate at which he can absorb energy of radiation, in joules per year
