Black body radiation is emitted by two circular stars A and B. Radius of A is 400 times radius of B and energy emitted by star A is \(10^4\) times, energy emitted by star B. Find the ratio of their wavelengths \((\frac {\lambda _A}{\lambda_B} )\) When radiation curves are at peak.

In the flagella of gram negative bacteria there are 4 rings i.e; L,P,S & M whereas in flagella of gram positive bacteria there are only 2 rings i.e; S & M. Right? My question is if there is peptidoglycan layer present in gram positive bacteria, why doesn't it bear P ring as peptidoglycan layer of gram negative bacteria does?
