Suppose the number of red, pink, and white individuals in another population of flowers was 555, 555, and 555 respectively.

A) Could this population be said to be in H-W equilibrium. Show your work!

Thanks for any help.

I cleaned the keyboard of my MacBook pro with some weak cleaning agent and now the keyboard doesn't work and the mouse can only right click.

I have been at it for over a day now and I still can't fix it. Any help would be appreciated.

What are some simple ways to tell if a compound if aromatic or not?

I ve been working on this one for a bit but I don t know what to do.

Here is the question:

A thin film of soapy water, n = 1.37, is held vertical. Light of wavelength 600 nm is reflected from the film

and horizontal dark lines appear. What is the difference in thickness of the soap film from one band to the next?

A 25 cm focal length convex mirror has a 3.0 cm tall object placed 20 cm in front of it. Where is the image, and is it real or virtual?

A 6 cm candle is place 20 cm in front of a convex mirror that has a focal length of -15 cm. Use the mirror equation to find the location of the image and its characteristics.

A beam of light in air is incident on a stack of four flat transparent materials with indices of refraction 1.20, 1.40, 1.32, and 1.28. If the angle of incidence for the beam on the first four materials is 60.0 degrees, what angle does the beam make with the normal when it emerges into the air after passing through the entire stack?

UNPOLARIZED LIGHT OF INTENSITY Io is sent through 4 polarizers, each of the three rotated 30 degrees from the previous polarizer so that the last polarizer is perpendicular to the first. What is the intensity transmitted by this system?

Light of wavelength 659.6 nm is emitted by a star. The wavelength of this light as measured on Earth is 661.1 nm. How fast is the star moving with respect to the Earth? Is it moving toward Earth or away from it? The wavelength shift is small so v<<c

If the intensity of radiation from the sun is 1.4kw/m2 at a distance of 150 x 10^6km, at what distance is the intensity of 5.6 kw/m^2?

PLEASE SHOW WORK WITH NUMBERS IF POSSIBLE.

How fast would you have to drive in order to see a red light as green? assume λ = 630 nm for red and λ = 530 nm for green.

Please show work.

If the intensity of radiation from the sun is 1.4kw/m2 at a distance of 150 x 10^6, at what distance is the intensity of 5.6 kw/m^2?

In a Diels-Alder reaction between cyclopentadiene and Maleic Anhydride to form cis-Norborene-5-6-endo-dicarboxylic Anhydride, is there a side reaction? If so, what is it?

I already know the main reaction, but I couldn't determine if there was a side reaction or not.

The resistance of a wire increases 3.9% when the temperature of the wire is raised 100 degrees C. What is the temperature coefficient of resistivity of the wire material?

An electron is moving at 3.6 × 106

m/s perpendicular to a uniform magnetic field. If the radius of the motion

is 18 mm, what is the magnitude of the magnetic field?

Please show work.

An electron moves with a speed 2.0 x 10^15 m/s in a 1.2 Tesla uniform magnetic field. At one instant, the electron is moving west and experiences an upward magnetic force of 3.2 x 10^-14 N. What is the direction of the magnetic field?

A common flashlight bulb is rated at .300 A and 2.90 V (the values of current and voltage under operating conditions). If the resistance of the bulb's tungsten filament at room temperature (20.0 C) is 1.10 ohms, estimate the temperature of the tungsten filament when the bulb is turned on.

The answer is 1750 C, I just don't how to get to that answer.

The current in a wire is .500 A.

(a) How much charge flows through a cross section of the wire in 10.0s?

(b) How many electrons flow through the same cross section in 10.0s?

Here's the problem:

Find the electrical field and the potential at the center of a square of side 2.0 cm with charges of +9.0 uC at each corner.

I already found the electrical field, but I am having trouble finding the potential. I know the potential is 2.3 x 10^7, but I can't quite get that number in my calculations.

Two electric charges, q1 = +20. 0 nC and q2 = +10.0 nC, are located on the x-axis at x= 0m and x=1.00m, respectively. What is the magnitude of the electric field at the point x= .50 m, y= .50m?

The answer is 400 N/C, but I don't know how to calculate it. Please help!
