The numbers of each genotype were:

MM: 298

MN: 489

NN: 213

Assuming random mating, calculate the gene frequency for the M allele and the expected genotype frequencies. Use the chi-squared test to determine that mating is random.

at t= 0 a wheel (radius = 0.25m) initially turns at an angular velocity of 20rad/s. But it is also slowing at a rate of 4 rad/s^2.

a) what is the linear speed of the wheel halfway between the rim and center at t=0?

b) How many revolutions does it take to come to rest? and how long does it take to come to rest?

Merry go round has radius R = 2.0 m and rotational inertia I = 500 kgm^2. When the merry go round is at rest a child (mass m = 25 kg) runs with speed v along a tangential line to the rim and jumps on. Final angular velocity of merry go round is 0.75 rad/s.

a) What's the child's speed?

b) Child crawls along a diameter from rim to center. Find the final angular velocity of merry go round.

Thanks for your help!

Bromocyclohexane reacts with HNO3 and H2SO4? what's the product?

Your help is appreciated :)

Use nested loops

I know it is for lateral water transport but there has to be more to it. =]

For instance a reaction order of 1 for a specific substance is namely, first order reaction. What about a reaction order of 0.50? Half order reaction possibly?

Also, how do you calculate corrected absorbance?

x = 9

y = sqrt(x)

y=(1/2)x

Thanks! =]

Chemistry Lab

What is the difference between wavelengths observed in white light and in a solution that allows white light to go through it?

Can an initial volume of a buret be 0.0121?

For instance, chlorophyll a and b and xanthophyll and carotene?

What questions could I answer and elaborate on in my acid-base titration lab conclusion?

We used NaOH (base) & H2SO4(acid).

I know the molecular formula but is the molar mass of the Octahydrate multiplied or added to the Cobalt (II) Phosphate mass?

What is the most common hydrate for Cobalt (II) Phosphate?

I am doing a chemistry lab on the empirical formula of MgO. I was asked to use the average ratio to calculate the percent error. How do I do that?

My average ratio was 1 Mg:2 O

I know that SF6 is called sulfur hexaflouride but my homework question has asked me to avoid the "common names." I need help trying to figure out a different name...as it is, it won't accept my answer.

I'm doing a poster in Save Me A Spot In College Contest. I need some opinions to employ into my poster as my research on california students. help me out =) please! write your name at the bottom and I'll use it as reference on my poster =) Thanks!
