Answer:
Option B
Explanation:
An lunar eclipse occurs when the Earth comes in between the Sun and the moon when all the three are aligned in space and the Earth casts its shadow on the phase of the full moon and thus darkens it usually the moon turns into a shade of copper red.
For the eclipse to occur every month the Earth's orbit around the sun must coincide with the moon's orbit around the earth.
It takes about a month for the moon to orbit the Earth and if the plane of the ecliptic orbit is the same as that of the orbit of the moon around the earth then there would be at least two lunar eclipses in a month, one at full moon and the other one fortnightly.
Explanation:
one light year is the distance traveled by the light in 365.25 days. Thus,
1 year is 365.25 days.
1 day is 24 hour
1 hour is 60 minute
1 minute is 60 second
thus, 365.25*24*60*60 is 31557600 second.
Answer:
1 light year is approximately 9.4607 trillion km
Answer:
Yes Newton's laws apply to small objects
EX: Newton s first law
when body at rest always want to be at rest
or body at motion always want to be at motion
unles an external force acts upon it
for example a eraser on the table will be at rest
if so e apply some force then it comes motion
so, Newton s law apply to small object s
