A 14N14N molecule is vibrating in its ground state with a spring constant of 2233 N m−1. What is the wavelength of the photon which excited this system to the first excited state? Use scientific notation to express your answer (X. XXE-X).

Which graph best represents the relationship between the electric current and the rate at which a magnet is turning inside an electric generator?

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

Iwill give 30 points to whoever answers ! what is the formula for actual mechanical advantage and ideal mechanical advantage?
