Answer:
When electric voltage is applied, an electric field within the metal triggers the movement of the electrons, making them shift from one end to another end of the conductor. Electrons will move toward the positive side.
b
Explanation:
doing same amount of work while increase in amount of heat released
The density is still rho. It doesn't change. The density of a substance is the density of the substance. It doesn't depend on how much of it you have.
θ = 66.90°
we know that
I= intensity of polarized light =1
I_o= intensity of unpolarized light = 13
putting vales we get
⇒
therefore θ = 66.90°
