Answer:
false. it's positive terminal of an electric cell
'ml' and 'cm³' are exactly the same volume, and they're both metric units.
If you're asking about volume measurements in the USA, then
fasten your seat belt. It's going to be a bumpy ride:
-- 29.5735295625 ml makes 1 US fluid ounce
-- 8 US fluid ounces makes 1 US cup
-- 2 US cups makes 1 US pint (16 US fluid ounces)
-- 2 US pints makes 1 US quart (32 US fluid ounces, 4 US cups)
-- 4 US quarts makes 1 US gallon
(8 US pints, 16 US cups, 128 US fluid ounces, 231 cubic inches)
Answer: well it keeps the international space station in orbits around the earth and gravity keeps the moon keep orbiting the earth

Answer:
= 4,574 10⁻⁵ m
Explanation:
The interference pattern for a two slit system is given by
d sin θ = m λ constructive interference
d sin θ= (m + ½) λ destructive interference
In general and also in this case the screen is far from the slits, so the TT-free can approach the TT
tan θ = y / L
Let's replace
d y / L = m λ constructive interference
d y / L = (m + ½) λ destructive interference
Let's start when there is constructive interference
They give us the frequency of light, let's find the wavelength
c = λ f
λ = c / f
λ = 3 10⁸ / 6.32 10¹⁴
λ = 4.7468 10⁻⁷ m
Let's take the opportunity to reduce the SI system
L = 87 cm = 0.87 m
y = 3.16 cm = 0.0316 m
Now we can find the separation of the slits
d = m λ L / Y
d = 3 4.7468 10⁻⁷ 0.87 / 0.0316
d = 3.92 10⁻⁵ m
We already have all the data, now let's use the destructive interference equation and find
d / L = (m + ½) λ
= (m + ½) λ L / d
= (3 + ½) 4.7468 10⁻⁷ 0.87 / 0.0316
= 4,574 10⁻⁵ m
