Amolecule gives the following data: mass spectrum: molecular ion, m=138 m/z, relative intensity of m: m+1: m+2 peaks is 100 : 2.2 : 100 infrared spectrum: 3300 cm^-1 (extremely broad and strong)1750 cm^-1 (strong)using the information given above, determine the molecular formula of the compound. show all your work.

c)as speed changes, wavelength and frequency change.

everything changes!

this is a good question! i'll do some research and come back when i have the answer!

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.

it is called kinetic energy
