It is illegal for adults to drive when they have what BAC level? (a) 0.01, (b) 0.02, (c) 0.05, (d) 0.08.

Explain why genes $A 2$ and $B 2$ (discussed earlier) are orthologs and not paralogs.

A 1-in-diameter solid round bar has a groove 0.1-in deep with a 0.1-in radius machined into it. The bar is made of AISI 1020 CD steel and is subjected to a purely reversing torque of $1800 \text { lbf } \times \text { in }$. a) Estimate the number of cycles to failure. b) If the bar is also placed in an environment with a temperature of $750^{\circ} \mathrm{F}$, estimate the number of cycles to failure.

A solid circular aluminum alloy ( $G=4000\ \mathrm{ksi}$ ) shaft with diameters of $2.5\ \mathrm{in}$. and $1.75\ \mathrm{in}$. is subjected to a torque $T$, as shown in given figure. The shearing stress is limited to $8000\ \mathrm{psi}$, and the angle of twist in the $7-\mathrm{ft}$ length cannot exceed $0.04\ \mathrm{rad}$. Find the maximum permissible value of $T$.

If a state has a zero-tolerance level of 0.02 percent BAC, what does this mean?

Solve each formula from electricity and radio for the indicated variable. $v=\sqrt{\frac{2 K}{m}}$ for m

Is a standard coffee mug equivalent by distortion to a solid doughnut? Explain why or why not.

A car has two homs, one emitting a frequency of 199 $\mathrm{Hz}$ and the other emitting a frequency of $203 \mathrm{~Hz}$. What beat frequency do they produce?

Find the volume of the solid of revolution formed by rotating the region $R$ about the $x$ axis.

$R$ is the region under the curve $y=\sqrt{x}$ from $x=1$ to $x=4$.

Why doesn’t convection occur in a solid material?

Integrate the given function over the indicated region W. $f (x, y, z) = 4x + y;$ W is the region bounded by $x = y^2, y = z, x = y,$ and $z = 0.$

A horizontal spring system has a spring with constant. 628 N/m and a block of mass 8.00 kg, lying on a frictionless surface, attached to the free end. The block is pulled a short distance from equilibrium and released. Calculate the frequency.

How does the theoretical strength of a solid material compare with its experimental strength?

In fruit flies, the genes for wing shape and body stripes are linked. In a fly whose genotype is WwSs, W is linked to S, and w is linked to s. Show how this fly can produce gametes containing four different combinations of alleles. Which are parental-type gametes? Which are recombinant gametes? How are the recombinants produced?
