Answer:
moon's motion without gravity
Explanation:
The reason it's moon's motion without gravity is because if you take away earths gravitational pull it would simply go in the direction it last was, and the last direction it was, was where the dotted arrow is.
Answer:
If the frequency is doubled, the wavelength is only half as long.
Explanation:
Wave speed equals frequency*wavelength. So doubling the frequency must halve the wavelength in order for wave speed to remain the same.
Answer:
mass and height of the object.
Answer:
a. 10.0 g
Explanation:
The molar mass of NaOH is 39.997 grams which was calculated by adding the molar mass of Sodium, Oxygen, and Hydrogen
. But before we do anything with this number we must first convert
molecules to moles. We can do this by dividing by Avogadro's number or
(
moles). We then convert moles to grams by multiplying by the molar mass of NaOH, (
grams). This is almost exactly 10 and the margin of error is likely due to the original numbers not being precise enough.
