Because of nickel's slow rate of oxidation at room temperature, it is considered corrosion-resistant. Historically, this has led to its use for plating metals such as iron and brass, coating chemistry equipment, and manufacturing certain alloys that retain a high silvery polish, such as German silver.
Which characteristic are shared by Electromagnetic and mechanical waves? Check ALL that apply. A.both have a crest and a trough B.both move due to particles bumping into each other C.both can move through matter D.both can occur as a result of a disturbance E. Both are formed by charged particles.
An electromagnetic (EM) wave is not a sound wave. A sound wave is mechanical energy, and an electromagnetic wave is electromagnetic energy. The EM wave could be a radio or light wave, but in any case, it is composed of moving electric and magnetic fields. This electromagnetic wave can move through air or the vacuum of space, but sound (or any mechanical wave) must have a medium to travel through.
