Fill in the blanks : Ozone layer prevents the harmful……………… radiation of the sun to reach the earth.

The upper stratosphere consists of considerable amount of X. X protects us from the harmful ultraviolet radiations coming from the sun. These radiations cause skin cancer (melanoma) in humans. X is :

Escape velocity from the surface of moon is less than that from the surface of earth because the moon has no atmosphere while earth has a very dense one.

Why do ultraviolet rays and infrared rays reach the earth's surface in very small amounts?

A satellite orbiting close to the surface of earth does not fall down because the gravitational pull of earth

(A):A balloon ascends from the surface of earth with constant speed.When it was at a height 50m above the ground,a packet is dropped from it .To an abserver on the balloon,the displacement of the packet,from the moment it is dropped to the moment it reaches the surface of earth is 50m. (R ):Displacement vector does not depend upon the reference frame used to measure it.

Stratosphere contains a stable layer of ozone molecules which absorbs UV radiation from the sun. The presence of ozone in atmosphere serves, as a shield to protect living organism on earth from the harmful effects of the solar ultraviolet radiation. The ultraviolet radiation are known to cause skin cancer. Ozone is formed in stratosphere by the following photochemical reactions. O_(2)(g)overset(UV)rarrO(g)+O(g) O(g)+O_(2)(g)overset(UV)hArrO_(3)(g) Ozone is thormodhynamically unstable and ecomposes to molecular oxygen. Thus a dynamic equilibrium exits between the production and decomposition of ozone molecules. Earth is protected from UV radiation by

STATEMENT -1 : An orbiting satellite orbiting round the earth, misses the path and starts moving towards the earth, but before reaching the Earth's surface it is burnt in the dense atmosphere of earth. and STATEMENT -2 : As the satellite move towards earth, its speed goes on increasing. It is burnt due to high heat production because of enormous large speed in dense atmosphere.
