A. 1 and 2 Point 1 is correct and simple to understand. Point 2 is correct because some water would have evaporated after it reached boiling point. Point 3 is incorrect because the heating started at 3 and it reached boiling point at 6. So it took 3 minutes to reach boiling point. Point 4 is incorrect because as per the graph water was heated from point 3 till point 11 i.e. for 8 minutes.

The distance of the image in the mirror s the same as it is in reality.So Sachin is sitting 3 meters away from the mirror and the image is forming 7 meters away from the mirror . Then 3 meters 4 meters= 7 meters and the image will be formed 14 meters away from the object.

A. Compass The red pointer in a compass (or the magnetized needle on a home-made compass) is a magnet that is being attracted by Earth's own magnetism. So the north end of a compass magnet is drawn to align with the Earth's magnetic field. Because the Earth's magnetic North Pole attracts the "north" ends of other magnets, it is technically the "South Pole" of our planet's magnetic field.

AWhile being photosynthetic, X consumes oxygen at a faster rate than it releases the same, because of its high rate of growth.
BBecause X is highly invasive, it incorporates a large quantity of oxygen in its biomass.
