Why did we define the blackbody radiation function? What does it represent? For what is it used?

Sticky Polymers Inc. processes a base chemical into plastic. Standard costs and actual costs for direct materials, direct labor, and factory overhead incurred for the manufacture of 10,750 units of product were as follows:

$$\begin{array}{llll} {\text{\hspace{100pt}}}&{\hspace{20pt}\textbf{Standard Costs}\hspace{10pt}}&\hspace{25pt}\textbf{Actual Costs}\hspace{20pt}\\\hline \text{Direct materials}&\text{3,700 lbs. at \$12.00}&\hspace{10pt}\text{3,500 lbs. at \$12.50}\\ \text{Direct labor}&\text{4,300 hrs. at \$20.00}&\hspace{10pt}\text{4,200 hrs. at \$20.40}\\ \text{Factory overhead}&\text{Rates per direct labor hr.,}\\ &\text{based on 100\\\% of normal}\\ &\text{capacity of 4,500 direct}\\ &\text{labor hrs.:}\\ &\text{\hspace{15pt}Variable cost, \$4.00}&\hspace{10pt}\text{\$16,800 variable cost}\\ &\text{\hspace{15pt}Fixed cost, \$3.00}&\hspace{10pt}\text{\$13,500 fixed cost}\\ \end{array}$$

Each unit requires 0.4 hour of direct labor.

Determine (c) the variable factory overhead controllable variance, fixed factory overhead volume variance, and total factory overhead cost variance.

What is the most common form of weathering at high-latitude and high-altitude locations? (1) frost action (2) chemical weathering (3) mineral changes (4) solution in water

A variable star is one whose brightness alternately increases and decreases. For the most visible variable star, Delta Cephei, the time between periods of maximum brightness is 5.4 days, the average brightness (or magnitude) of the star is 4.0, and its brightness varies by ±0.35 magnitude. Find a function that models the brightness of Delta Cephei as a function of time.

In the below reaction, identify which element is oxidized and which is reduced by assigning oxidation numbers:

$$\text{$2 \mathrm{Ag}(s)+2 \mathrm{HNO}_3(a q) \rightarrow 2 \mathrm{AgNO}_3(a q)+\mathrm{H}_2(g)$}$$

Choose T if the statement is true. Choose F if the statement is false.

Hypofractionation refers to the dosage of radiation. T F

Is there a lowest temperature below which black body radiation is no longer given off by an object? Explain.

An experiment was carried out with 10 randomly selected patients suffering from insomnia to investigate the effectiveness of a drug that was designed to increase sleep time. The data show the number of additional hours of sleep gained by each subject after taking the drug. (A negative value indicates that the subject got less sleep after taking the drug.)

$$1.9 \quad 0.8 \quad 1.1 \quad 0.1 \quad -0.1 \quad 4.4 \quad 5.5 \quad 1.6 \quad 4.6 \quad 3.4$$

Why should you use one-sample t procedures to perform inference about a mean difference in this setting?

Briefly describe how the intensity and duration of solar radiation change at your location throughout the year.

A tax auditor reviewing a tax return looks for several kinds of problems, including $(1)$ mistakes made in entering or calculating numbers on the tax return and $(2)$ places where the taxpayer reported income dishonestly. Discuss whether each problem involves random or systematic errors.

What is the uncertainty in using pressure measurement as an altimeter? A gage on the side of an airplane measures a local pressure of $54 \mathrm{kPa}$, with an uncertainty of $3 \mathrm{kPa}$. The estimated lapse rate that day is $0.007 \mathrm{~K} / \mathrm{m}$, with an uncertainty of $0.001 \mathrm{~K} / \mathrm{m}$. Effective sea-level temperature is $10^{\circ} \mathrm{C}$, with an uncertainty of $4^{\circ} \mathrm{C}$. Effective sea-level pressure is $100 \mathrm{kPa}$, with an uncertainty of $3 \mathrm{kPa}$. Estimate the airplane's altitude and its uncertainty.

How do astronauts protect themselves against radiation hazards when they are working outside the ISS?

What effects of light radiation and reflection are responsible for the fact that we can see objects in a room?
