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)

- Two cities X and Y are connected by a regular bus service with a bus leaving in either direction every T min. A girl is driving scooty with a speed of 60 km/h in the direction X to Y. She notices that a bus goes past her every 30 minutes in the direction of her motion, and every 10 minutes in the opposite direction. Choose the correct option for the period T of the bus service and the speed (assumed constant) of the buses.

Eurkaryotic Cells - Golgi Apparatus
The Golgi apparatus is also known as the Golgi complex or the Golgi body. The term is derived from Camillo Golgi, the scientist who discovered the organelle. It can be found in all eukaryotic cells, including plants and animals. They are membrane-bound organelles found in the cell's cytoplasm.
Formation of acrosome: The acrosome is a component of the tip of animal sperms that aids in the digestion of the egg or ovum covering sheath during fertilisation. The Golgi complex produces it with the help of its vesicles.
