Two-thirds of the weight of a 1500kg car rests on the drive wheels. Assume that μs = 0.74. What is the maximum acceleration of this car on a concrete surface?

There is a 100g mass sitting on the 10cm mark, and a 50g mass sitting on the 60cm mark. Force 𝐹 acts at the 30cm mark.

Why would you not be able to use a CD diffraction grating to measure the wavelength of laser light?

The work function energy of potassium is 2.2 eV. The surface of potassium is illuminated with electromagnetic radiation of a specific wavelength. Experiments show that the photoelectrons from potassium have kinetic energy in the range zero to 1.9 eV. Dete...

Thanks

Due to varying wavelengths, the wave speed of each constituent of the visible light spectrum will vary, and so will the angle at which the light will leave the diffraction grating. - Hope that makes some sense. (-:

Note; Please do not be offended by any of these comments, rather take it as constructive criticism upon which you can work. 1) The geese are a little out of the blue. If you are to mention them, then you should focus the next stanza on them at least, to p...

Thank you very much for this file. It was really helpful. (-:

The phrase "All you would do was dreamily sigh" sounds a little wierd, and out of place. Try something like "Stimulating the sound of a dreamy sigh", or "a blessed song for the eye"

"This was a gentle night" is too short a line in the last stanza, compared to "It was a delightfully breathtaking sight." It also isn't an effective ending for your poem. The last line should be powerful, try something creative and metaphoric. Add a twist...
