Answer:
None of the above
Explanation:
When energy is converted from one form to another in a chemical or physical change, none will change. This is due to the law of conservation of energy. It states that the total energy of the system remains constant. It only changes energy from one form of energy to another. So, the correct option is (d) "none of the above".
The redshift of light from galaxies and the uniform distribution of cosmic background radiation
Answer:
1/2
Explanation:
The energy stored in a capacitor is given by:
where
C is the capacitance
V is the potential difference
For capacitor 1, we have
Capacitor 2 has
(half the capacitance of capacitor 1)
(twice the potential difference of capacitor 1)
So the energy of capacitor 2 is
So, the ratio between the two energies is
