g If you have a light in your house on a dimmer switch you should try this yourself. In the space below write a paragraph about how the light from an incandescent source changes as the temperature decreases. Notice changes in both how bright the light is and what colors/wavelengths of light you can see. If you have such a light at your house you can also describe how the color and intensity of the light changes when you are just looking with your eyes and not through the spectrometer.

An electron is ejected into a horizontal uniform e⃗ field at a parallel horizontal velocity of v0. assume the electron's initial position x0, initial velocity v0, time t, magnitude of electric field e, electron's mass m, and the magnitude of the electron's charge |e|. ignore the force that earth exerts on the electron. assume the e⃗ field is in the same direction as the initial velocity. part a define the equation for the electron's velocity. express your answer in terms of the variables v0, |e|, t, e, and m.

Describe the work performed by a ski lift in terms of kinetic and gravitational potential energy

The safe load, l, of a wooden beam of width w, height h, and length l, supported at both ends, varies directly as the product of the width and the square of the height, and inversely as the length. a wooden beam 4 inches wide, 9 inches high, and 240 inches long can hold a load of 6810 pounds. what load would a beam 3 inches wide, 8 inches high, and 144 inches long, of the same material, support? (round off your answer to the nearest integer.)
