The ionic substance strontium oxide, SrO, forms from the reaction of strontium metal with molecular oxygen. The arrangement of the ions in solid SrO is analogous to that in solid NaCl: Write a balanced equation for the formation of SrO(s) from its elements.

A car magazine article states that the power $\dot{W}$ delivered by an automobile engine, in hp, is calculated by multiplying the torque $\mathscr{T}$, in $\mathrm{ft} \cdot \mathrm{lb} \mathrm{f}$, by the rotational speed of the driveshaft $\omega$, in RPM, and dividing by a constant:

$$\dot{W}=\frac{\mathscr{T} \omega}{\mathrm{C}}$$

. What is the value and units of the constant C?

What details in these lines demonstrate Beowulf's superhuman strength?

A test of null hypothesis against alternative hypothesis, where the null hypothesis states that the mean is 0 while for alternative hypothesis states that the mean is not equal to 0 has test statistic of z = 1.876. Is this test statistically significant at the 5% level ($\alpha$= 0.05)?ls it statistically significant at the 1% level ($\alpha$ = 0.01) ?

(a) What is the angular momentum of a figure skater spinning (with arms in close to her body) at $3.5$ rev/s, assuming her to be a uniform cylinder with a height of $1.5$ m, a radius of $15$ cm, and a mass of $55$ kg. (b) How much torque is required to slow her to a stop in $5.0$ s, assuming she does $\it{not}$ move her arms?

Sketch the region bounded by the graphs of the algebraic functions f(y)=y(2-y) and g(y)=-y, and find the area of the region.

Lactose intolerance is sometimes treated by removing lactose from the diet. For example, infants with lactose intolerance may be given a lactose-free milk substitute to avoid the indigestion, diarrhea, abdominal discomfort, and other symptoms of this condition. Older children and adults with lactose intolerance may avoid dairy products and other foods high in lactose. Your friend Aileen, who has lactose intolerance, takes a tablet with her favorite ice cream (chocolate fudge) that helps her avoid any problems. What might this tablet contain?
