Answer:
463.4 m/s
Explanation:
The escape velocity on the surface of a planet/asteroid is given by
(1)
where
G is the gravitational constant
M is the mass of the planet/asteroid
R is the radius of the planet/asteroid
For the asteroid in this problem, we know
is the density
is the volume
So we can find its mass:
Also, the asteroid is approximately spherical, so its volume is given by
where R is the radius. Solving the formula for R, we find its radius:
![R=\sqrt[3]{\frac{3V}{4\pi}}=\sqrt[3]{\frac{3(3.32\cdot 10^{12}m^3)}{4\pi}}=9256 m](https://tex.z-dn.net/?f=R%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B3V%7D%7B4%5Cpi%7D%7D%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B3%283.32%5Ccdot%2010%5E%7B12%7Dm%5E3%29%7D%7B4%5Cpi%7D%7D%3D9256%20m)
So now we can use eq.(1) to find the escape velocity:
Technically, I can't answer the question, because you won't
let me see the picture that goes along with it and is a part of it.
But I'm familiar with the set-up, have dealt with the question before,
and I can answer it from my previous experience and general knowledge.
If there is 500g of mass inside the jar when you lower it over
the candle, then there will be 500g of mass at any time after that,
forever, or until you pick up the jar and take some mass out or put
some more in. It doesn't matter how long you wait. It also doesn't
matter whether or not the candle is burning, whether or not the sun
is shining on the jar, or whether somebody comes along and spray-paints
the outside of the jar with black paint. Matter is not created or destroyed.
Whatever mass was inside when the jar got closed stays in there.
Deforestation because it gets rid of the nature and soon the land will be empty and dry
