-- 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.
Answer: 
Explanation:
where;
= final velocity = 0
= initial velocity = 60 km/h = 16.67 m/s
= acceleration
= distance
First all of, because acceleration is given in m/s and not km/h, you need to convert 60km/h to m/s. Our conversion factors here are 1km = 1000m and 1h = 3600s
Solve for a;
Begin by subtracting 
Divide by 2d
Now plug in your values:
If you're wondering why I calculated acceleration first is because in order to find force, we need 2 things: mass and acceleration.
m = mass = 900kg
a = acceleration = -2.78m/s
It's negative because the force has to be applied in the opposite direction that the car is moving.
For a full wave bridge you don't want a center tap
Explanation:
Sound travels faster In solids than liquid than gases
Speed of sound is highest in solids, and higher in liquids and slower in gases. Example- Sound travels in air with the speed of 330 m/s, In steel it travels with a speed of 5920 m/s, In liquids it travels with a speed of 5000 m/s.
