Gravitational waves: Waves are created on the surface of water when we drop a stone into it. Similarly you must have seen the waves generated on a strintg when both its ends are held in hand and it is shaken. Light is also a type of wave called the electromagnetic wave. Gamma rays, X-rays, ultraviolet rays, infrared rays, microwave and radio waves are all different types of electromagnetic waves. Astronomical objects emit these waves and we receive them using our instruments. All our knowledge about the universe has been obtained through these waves. Gravitational waves are a very different type of waves. They have been called the waves on the fabric of space-time. Insteine predicted their existence in 1916. These waves are very weak and it is very difficult to detect them. Scientists have constructed extremely sensitive instruments to detect the gravitational waves emitted by astronomical sources. Among these, LIGO (Laser Interferometrc Gravitational Wave Observatory) is the prominent one. Exactly after hundred years of their prediction, scientists detected these waves coming from an astronomical source. Indian scientist have contributed significantly in this discovery. This discovery has opened a new path to obtain information about the Universe. Is it easy to detect Gravitational waves?

Assume that the chances of a patient having a heart attack is 40%. It is also assumed that a meditation and yoga course reduce the risk of heart attack by 30% and prescription of certain drug reduces its chance by 25%. At a time a patient can choose any one of the two options with equal probabilities. It is given that after going through one of the two options the patient selected at random suffers a heart attack. Find the probability that the patient followed a course of meditation and yoga?

Read the following statements regarding the various techniques used in cancer detection. (i) Cancer detection is based on biopsy and histopathological studies of the tissue, and blood and bone marrow tests for increased cell counts in case of leukaemia. (ii) In biopsy, a piece of the suspected tissue cut into thin sections is stained and examined under microscope by a pathologist. (iii) Techniques like radiography (use of X-rays), CT (computed tomography) and MRI(magnetic resonance imaging) are very useful to detect cancers of the internal organs. (iv) Computed tomography uses strong magnetic fileds and non-ionising radiations to detect physiological changes in living tissues. (v) MRI uses X-rays and ionising radiation to generate a 3-D image of the internal structure of an object. Which of the above statements are incorrect ?

A person suffering from a disease caused by Plasmodium, experiences recurring chill and fever at the time when (a) the sporozoites released from RBCs are being rapidly killed and broken down inside spleen (b) the trophozoites reach maximum growth and give out certain toxins (c) the parasite after its rapid multiplication inside RBCs ruptures them, releasing the stage to enter fresh RBCs (d) the microgametocytes and megagametocyte are being destroyed by the WBCs

A magnetic field that varies in magnitude from point to point but has a constant direction (east to west) is set up in a chamber. A charged particle enters the chamber and travels undeflected along a straight path with constant speed. What can you say about the initial velocity of the particle? A charged particle enters an environment of a strong and non-uniform magnetic field varying from point to point both in magnitude and direction, and comes out of It following a complicated trajectory. Would its final speed equal the initial speed if it suffered no collisions with the environment? An electron travelling west to east enters a chamber baving a uniform electrostatic field in north to south direction. Specify the direction in which a uniform magnetic field should be set up to prevent the electron from deflecting from its straight line path.

Read the paragraph given below. Based on the paragraph and your acquired knowledge and understanding, answer the question. ''A traditional strategy for the protection of biodiversity has been in practice in India and some other Asian countries dimensions protected by tribal communities due to religious sanctity accorded to them. The sacred forests represent islands of pristine forests and have been free from all disturbances, though these are frequently surrounded by highly degraded landscape. In India, sacred forests are located in several parts e.g. Karnataka, Maharashtra, Kerala, Meghalaya etc and are serving as refugia for number of rare, endangered and endemic taxa.'' a. In India which are the major locations of sacred forests? b. By considering a sacred forest in your local area, list any two ecological significances of sacred forests. c. Due to the religious sanctity, sacred forests are protected to a certain extent. Do you agree? Justify your opinion.
