Explanation:
1. The full Moon rises just after the Sun sets. So lets assume the Sun sets at 06:00 pm then the Moon will rise at 06:00 pm. This happens because of the position of Moon with respect to Sun. It is opposite to the Sun as seen from Earth.
2. Lets assume that Sun rise will happen at 06:00 am so Moon will be visible till 06:00 am and it will reach highest point in the Sky at 00:00 am that is midnight. This is the time when it will cross the meridian line.
3. No, we can never see the Sun going through phases no matter where we are. The Moon shows us phases because it doesn't have its own light and reflects light of the Sun. But Sun is a star and has it own light. Sun will always be seen like a full circle.
If it soaks into the earths surface it becomes ground water
A white-blue star is indeed hotter than a red star. So True :)
Answer:
Explanation:
We shall apply Gauss's theorem for electric flux to solve the problem . According to this theorem , total electric flux coming out of a charge q can be given by the following relation .
∫ E ds = q / ε
Here q is assumed to be enclosed in a closed surface , E is electric intensity on the surface so
∫ E ds represents total electric flux passing through the closed surface due to charge q enclosed in the surface .
This also represents total flux coming out of the charge q on all sides .
This is equal to q / ε where ε is a constant called permittivity which depends upon the medium enclosing the charge . For air , its value is 8.85 x 10⁻¹² .
If charge remains the same but radius of the sphere enclosing the charge is doubled , the flux coming out of charge will remain the same .
It is so because flux coming out of charge q is q / ε . It does not depend upon surface area enclosing the charge . It depends upon two factors
1 ) charge q and
2 ) the permittivity of medium ε around .

Answer:</h2>
The distance will be 1800 m
<h2>
Explanation</h2>
As in question
Time = 15 min
Time = 15 x 60 sec = 900 sec
Speed = 2 m/s
We know that
So, the answer is 1800 m
