Consider a box full of a monatomic ideal gas. even for an ideal gas, the atoms are colliding with one another at a fantastic rate, perhaps each atom having a collision every 10-10 second. it might seem reasonable to think that given all of the collisions between atoms, after a brief time, the atoms would end up equally sharing their translational energy. that is, all molecules would be moving at the speed i. e. with the same fact, is that the speeds are distributed through a very large range, as shown in (6.50) magnitude of velocity however, what is found in same in a few sentences (so in words-no equations needed), describe why having distribution of speeds is expected.

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
