One type of sunburn occurs on exposure to UV light with a wavelength in the vicinity of 325 nm. What is the energy of a mole of these photons?

Energy of a mole of these photons is  

Explanation:

The relationship between wavelength and energy of the wave for 1 mole follows the equation:

E= energy

N= avogadros number =

= wavelength of the wave  =    

h = Planck's constant  =

c = speed of light =

Thus the energy of a mole of these photons is  

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
