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:

Answer:
Radiation
Explanation:
The heat transfer take place by three modes
1. Conduction
This type of heat transfer take place in the solid materials like metals .This heat transfer take place due to vibration of electron.
2.Convection
This type of heat transfer take place in the moving fluid like water ,air etc.
3.Radiation
Every materials which having temperature above 0 K are emitting radiation.This type of heat transfer dominate at the high temperature.
We know that temperature of sun is so high so the heat transfer from sun to the earth is take place by radiation mainly.
Be easy-going and be yourself.
warm fluids are less dense than cold fluids
