Type of electromagnetic wave that causes skin cancer from the sun and kills germs in hospital.

where's the following? you gotta add it to know what the choices are

explanation:

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.

in physics zero. in muscle fatigue could be high

no. dot product   =0 when vecs at right angles
