Explanation:
(A) Electric field for the parallel plate capacitor is given by :
It is clear that the electric field does not depend on the separation of the plates.
(B) The relation between the electric field and the electric potential is given by :
d is the separation between plates. So, if the separation of the plates is increased, the potential difference increases.
(C) The capacitance of the parallel plate capacitor is given by :
So, the capacitance decreases when the separation of the plates is increased.
(D) The energy stored in the capacitor is given by :
So, the energy stored in the capacitor is increased when the separation of the plates is increased.
Answer:
Explanation:
From the question we are told that
Speed of star 
Distance of spectral line 
Generally the equation for wavelength with respect to spectral lines is mathematically given by
where
therefore
Generally the equation for new wavelength is mathematically given as
Therefore

Answer:
True
Explanation:
Sound is all about vibrations.
The source of a sound vibrates, bumping into nearby air molecules which in turn bump into their neighbor's, and so forth.
