Answer:
C
Explanation:
The new moon is when the moon is not visible
F = ma
F = (1000 kg)•(5 m/s^2)
F = 5000 N
-- If you're observing the moon from a location in the northern hemisphere, like Canada, Russia, the US, or Israel, then it looks like this picture during the <em>waxing crescent</em> phase.
-- If you're observing the moon from a location in the <u>southern</u> hemisphere, like Australia, South Africa, Paraguay, or Antarctica, then it looks like this picture during the <u>waning</u> crescent phase.
Answer:
without answers to choose from, I'd say make sure you're using the same shape and sized containers, and they're placed in the same locations at the same time. also you'd probably get a more accurate result by leaving them longer than an hour, more like a day or 2, and do it on multiple different days, when the temperature is different each day and then take an average of those days...
Answer: 63 m/s
Explanation: If wheel drops vertically, you can use
conservation of energy : Ep = Ek. mgh = ½mv^2 and
solve v = √(2gh ) = √ (2·9.81 m/s²·200 m) = 62.6 m/s.
NOTE: wheel has also horizontal speed which was not mentioned here.
