Fatty acids: Are long-chain carboxylic acids. Palmitic acid (C) and arachidonic acid (B) are examples of fatty acids.
Amino acids: Glutamic acid (A) and aspartic acid (E) are amino acids, the building blocks of proteins. They are not fatty acids.
Phospholipid: Lecithin (D) is a type of phospholipid, a major component of cell membranes. While fatty acids are part of the structure of lecithin, lecithin itself is not a fatty acid.
Thus, the compounds that are not fatty acids are A, D, and E.

Consider a water tank shown in the figure. It has one wall at \(x = L\) and can be taken to be very wide in the z direction. When filled with a liquid of surface tension \(S\) and density \( \rho \), the liquid surface makes angle \( \theta_0 \) (\( \theta_0 < < 1 \)) with the x-axis at \(x = L\). If \(y(x)\) is the height of the surface then the equation for \(y(x)\) is: (take \(g\) as the acceleration due to gravity) 
AB is a part of an electrical circuit (see figure). The potential difference \(V_A - V_B\), at the instant when current \(i = 2\) A and is increasing at a rate of 1 amp/second is:
Among the following, choose the ones with an equal number of atoms.
Choose the correct answer from the options given below:
In an oscillating spring mass system, a spring is connected to a box filled with sand. As the box oscillates, sand leaks slowly out of the box vertically so that the average frequency ω(t) and average amplitude A(t) of the system change with time t. Which one of the following options schematically depicts these changes correctly?
