Questions Asked in NEET exam
- 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.

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 :

Concepts Used:
Antimicrobials
Infections and diseases may be caused by different types of organisms like bacteria, fungi, and viruses, etc., in humans and animals. Antimicrobial agent is the drugs that are used to prevent the pathogenicity of microorganisms.
Examples: Antibiotics, antiseptics, and disinfectants.
It is used to prevent infections and diseases caused by pathogens. Different types of antimicrobial drugs are commonly available. These are as follows:
- Antibacterial drug: is a drug that are used to inhibit the pathogenic activity of bacteria. Example: Zithromax.
- Antifungal drug: A drug that is used to prevent the fungal activity in the host is called an antifungal drug. Example: Miconazole
- Antiviral agent: A drug which is used to stop the pathogenic action of a virus is called as antiviral agents. Example: Tamiflu.
- Antiparasitic drug: is a drug that are used to prevent the growth of pathogenic parasites. Example: Anthelmintics
