Insert 16 rational numbers between 2.1 and 2.2

Inset 16 rational numbers between 2.1 and 2.2.

In the picture provided, what is the relationship between (1) and (2) with respect to population interaction and beween (3) and (4) with respect to trophic levels.

The energies E_(1) and E_(2) of two radiations are 25 eV and 50 eV respectively. The relation beween their wavelength i.e. lamda_(1) and lamda_(2) will be

Why is O_2 inert at room temperature ?

A train begins its journey from a station with a uniform acceleration of 0.2 "m.s"^(-2) and moves for 1 min. Next, it moves for a further 5 min at uniform velocity. It then appIies brakes producing a retardation of 0.3 "m.s"^(-2) and stops at the next station. What is the distance between the two station?
