A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :

- 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.

Prokaryotic Cells
Prokaryotic cells are single-celled microorganisms known to be the earliest on earth. Prokaryotes include Bacteria and Archaea. The photosynthetic prokaryotes include cyanobacteria that perform photosynthesis.
A prokaryotic cell contains a single membrane and therefore, all the reactions occur within the cytoplasm. They can be free-living or parasites.
Characteristics of Prokaryotic Cell:
Prokaryotic cells have different characteristic features such as:
- Lack of a nuclear membrane.
- Absence of Mitochondria, Golgi bodies, chloroplast, and lysosomes.
- Presence of genetic material on a single chromosome.
- Lack of histone proteins in the constituents of eukaryotic chromosomes.
- The cell wall is made up of carbohydrates and amino acids.
- The plasma membrane acts as the mitochondrial membrane carrying respiratory enzymes.
