Light is shone on a diffraction grating with d=7.25x10^-6 m. The third order (m=3) maximum occurs at an angle of 12.2. What is the wavelength of the light in nanometers?
(Hint: The answer will be between 400 and 700.)

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem

Chameleons catch insects with their tongues, which they can rapidly extend to great lengths. in a typical strike, the chameleon's tongue accelerates at a remarkable 220 m/s2 for 20 ms, then travels at constant speed for another 30 ms.
