Answer:
In the case of an electric bulb, the electrical energy is converted to light and heat. The amount of electrical energy put into a bulb = the amount of light energy (desirable form) plus the heat energy that comes out of the bulb (undesirable form).

Answer:
E the electric field remains unchanged.
Explanation:
potential difference between the plates of a capacitor
V = Q / C Where Q is charge on the capacitor and C is capacity of capacitor
Here Q is unchanged.
C the capacity has value equal to ε A / d
Here d is distance between plates. when it is halved, capacitance C becomes double.
V = Q /C , When C becomes double V becomes half
E = V/d , E is electric field between plates having separation of d.
When V becomes half and d also becomes half , there is no change in the value of E.
Hence E the electric field remains unchanged.
<h2>Answer:</h2>
<u>Blue main Sequence stars have the greater initial mass</u>
<h2>Explanation:</h2>
Blue main sequence stars are the stars with surface temperatures of 20,000 to 50,000 Kelvin and can be 25 times larger than the Sun. They are extremely hot so they have blue color. The best example of this type of stars is Rigel which is the brightest star in the constellation of Orion.
