Agamma ray is a high energy, high frequency electromagnetic wave that travels at the speed light 3.0 x 10^8 m/s calculate the wavelength of the wave if it's frequency is 10^20hz

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell

If an electric circuit is not grounded it is best to reach out and touch it to provide the ground a.true or b.false
