A sealed container of volume 0.1m^3 holds 3.0x10^24 atoms of helium gas at equilibrium. Distribution of speed of the helium atom shows a peak at 1100ms^-1.
i) calculate temperature and pressure of the helium gas.
ii) what is the average kinetic energy of the helium atoms?
iii) what is the...
Homework Statement
An asteroid of mass m = 2.6 × 10^6 kg approaches the Earth. When it is exactly 3 Earth radii away from the Earth's centre its speed relative to the Earth's centre is u = 8.7 × 10^3 m s–1.
The asteroid subsequently falls down to the Earth's surface. You may assume that the...
