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)

Classification of Animals
Classification of Animal Kingdom:
One of the most fundamental forms of classification of animals is the presence or absence of the notochord. Hence, two major groups exist, namely: Chordates and Non-chordates
Non-chordates and the Chordates-
- The notochord is a flexible rod made out of a material similar to cartilage. If an animal has a notochord during any stage of its life, it is classified as a chordate. Contrary to popular belief, chordates do not exclusively include vertebrates.
- There are invertebrates that possess a notochord during some point in their lives and hence, are classified as chordates. Thus all vertebrates are chordates but not all chordates are vertebrates.
Non-chordates-
- Non-chordates are animals without a notochord – the rod-like elastic structure that supports the body. This phylum consists of a small group of worm-like, marine species with an organ-system level of organization.
- Members of phylum Porifera, Coelenterata, Ctenophora, Platyhelminthes, Aschelminthes, Annelida, Arthropoda, Mollusca, Echinodermata and Hemichordata fall under Non-chordates
Vertebrates Classification:
The subphylum Vertebrata is divided into five classes of vertebrates. These five classes of vertebrates comprise of all the species of animals and have developed vertebral column as well as an internal skeleton.
Other characteristic features of vertebrates are-
- Presence of a true vertebral column and internal skeleton with muscle attachment points for body movement.
- A front-side muscular heart with two, three or four chambers.
- Kidneys for excretion and osmoregulation
- A paired appendages which may be fins or limbs.
- Possess notochord during the embryonic stage.
- Vertebrates are the only chordates to possess a brain as a part of the central nervous system.
Classification of Vertebrates-
- Pisces
- Amphibia
- Reptilia
- Aves
- Mammalia
