The frequency of a simple pendulum depends on?

Hemophilia is caused by an X-linked recessive allele. In a particular population, the frequency of males with hemophilia is $1/4000$. What is the expected frequency of females with hemophilia?

Two haploid strains of fungus are fused to form a diploid that produces eight-celled asci. Fungus strain A has the genotype + ade$1$ his$2$, and strain B is a $+$ $+$. The three genes are linked and occur in the order given.

a. The alleles at the A gene locus are determined in an ascus, and the order is aaaa $+$ $+$ $+$ $+$. Write the genotype for all three genes that you expect to find most commonly.

b. One ascus from the diploid is of the following type:

$+$ ade$1$ his$2$ $+$ ade$1$ his$2$ $+$ ade$1$ his$2$ $+$ade$1$ his$2$ a ade$1$ $+$ a $+$ $+$ a $+$ $+$ a $+$ $+$ Explain the events that produced this ascus.

c. One ascus from the diploid is of the following type: a $+$ $+$ a $+$ $+$ a $+$ his$2$ a $+$ his$2$ $+$ ade$1$ his$2$ $+$ ade$1$ his$2$ $+$ ade$1$ his$2$ $+$ ade$1$ his$2$

Explain the events that produced this ascus.

The buckets of the Pelton wheel deflect the 4-in.diameter water jet $120^{\circ}$ as shown. If the velocity of the water from the nozzle is $72 \mathrm{ft} / \mathrm{s}$, find the angular velocity of the wheel to produce a torque of $T=6.85\left(10^3\right) \mathrm{lb} \cdot \mathrm{ft}$ on the shaft. How fast must the wheel be turned to maximize the power developed by the wheel?

Calculate the ratio of NaF to HF required to create a buffer with pH = 4.00

An electrically neutral, linear, polar molecule has positive charge equivalent to the charge on one proton centered 0.30 nm from its center of mass and an equal quantity of negative charge centered 0.10 nm from its center of mass (opposite the positive charge). In an electric field of magnitude 100.0 N/C, what are (a) the greatest possible and (b) the smallest possible torque experienced by this molecule?

Work each problem.

What angle does the line $y=\sqrt{3} x$ make with the positive $x$-axis?

A cross was made between a plant that has blue flowers and purple seeds to a plant with white flowers and green seeds. The following data were obtained:
$\mathrm{F}_1$ generation: All offspring have blue flowers with purple seeds
$\mathrm{F}_2$ generation: 103 blue flowers, purple seeds
49 blue flowers, green seeds
44 white flowers, purple seeds $\frac{104}{300}$ white flowers, green seeds
Start with the hypothesis that blue flowers and purple seeds are dominant traits and that the two genes assort independently. Calculate a chi-square value. What does this value mean with regard to your hypothesis? If you decide to reject your hypothesis, which aspect of the hypothesis do you think is incorrect (i.e., blue flowers and purple seeds are dominant traits or the idea that the two genes assort independently)?

What is a relative frequency table?

Describe the frequency, wavelength and hertz.

Express the ratio as a fraction in simplest form. 18 quarts to 4 gallons

Express the ratio as a fraction in simplest form. 11 gallons to 11 quarts

When solid calcium carbonate $(CaCO_3)$ is heated, it decomposes to form solid calcium oxide $(CaO)$ and carbon dioxide gas $(CO_2)$. How many liters of carbon dioxide will be produced at STP if 2.38 kg of calcium carbonate reacts completely?

This butterfly valve $(D=12\ \mathrm{ft})$ is used to control the flow in a $12\ \mathrm{ft}$ diameter outlet pipe in a dam. In the position shown, the valve is closed. The valve is supported by a horizontal shaft through its center. The shaft is located $H=60\ \mathrm{ft}$ below the water surface. What torque would have to be applied to the shaft to hold the valve in the position shown?
