-- Starting from nothing (New Moon), the moon's shape grows ('waxes')
for half of the cycle, until it's full, and then it shrinks ('wanes') for the next
half of the cycle.
-- The moon's complete cycle of phases runs 29.53 days . . . roughly
four weeks.
-- So, beginning from New Moon, it spends about two weeks waxing until
it's full, and then another two weeks waning until it's all gone again.
-- After a Full Moon, the moon is waning for the next two weeks. So it's
definitely <em>waning</em> at <em><u>one week</u></em> after Full.
Free fall means your falling because of gravity and weight and will eventually hit the ground without any protection. weightlessness means a place or time where there is no gravity and you're floating and not falling.
Answer:
Yes, because the wrench is moving at the same speed as the sailboat.
The main difference is that a person on the ground would see the wrench moving diagonally, while a person on the boat would see the wrench falling straight down,
This difference in paths lead to the relativistic change in lengths.
Answer:
R/2
Explanation:
The potential at a distance r is given by :
Where
k is electrostatic constant
q is the charge
The potential (relative to infinity) due to a point charge is V at a distance R from this charge. So,
Put all the values,
<h3>So, the distance at which the potential (relative to infinity) is 2V is R/2.</h3>
