NADH_2 : 2 molecules of ATP :: FADH_2

A process is occurring throughout the day, in 'X' organism. Cells are participating in this process. During this process ATP, CO2 and water are evolved. It is not a light dependent. What could be the raw material of this process?

Unpolarized light of intensity I_0 is made to pass through three polarizers P_1, P_2 and P_3 successively. The polarization axis of P_2 makes an angle of theta_1 with that of P_1 , while that of P_3 makes an angle theta_2 with that of the P_2 . What will be the intensity of light coming out of P_3 ?

Choose the correct options At a given instant three point masses m, 2m and 3m are equidistant forces each other. Consider only the gravitational forces between them. Select correct statement//s for this instance only:
