Density is equal to mass divided my volume, so divide 38.6 by 2 to get the answer you need!
Answer:
The intensity is
Explanation:
From the question we are told that
The intensity of the unpolarized light is
The angle between the ideal polarizing sheet is
Generally the intensity of light emerging from the first polarizer is mathematically represented as
substituting values
Then the intensity of incident light emerging from the second polarizer is mathematically represented by Malus law as
substituting values
Answer: False
Explanation: In order to explain this problem we have to use the Faraday law, which say
dФm/dt=-ε it means that the variation of the magnetic field flux with time is equal to the emf ( electromotive force). In our case the magnetic flux is constant then there is not a emf induced in a wire closed loop.
Newton told him the orbits must have ellipses. Let me know if this helps.
the answer would be the last one because kinetic energy is something in motion.
hope it helps.
