Uniform Circular Motion
Uniform circular motion could be elaborates as the motion of an object within a circle at a constant speed. As an object moves within a circle, it is continually changing its direction. At all examples, the object is moving tangent to the circle. Because the direction of the velocity vector is the similar as the direction of the object's motion and the velocity vector is directed tangent to the circle as well. An animation at the right depicts this through means of a vector arrow.
Q. What are uses of ultra-violet radiations? Uses of ultra-violet radiations: (i) They are utilized to destroy the bacteria and for sterilizing surgical instruments.
EXAMPLES: (i) When the book is lying on a table, it exerts a downward force on the table (because of its weight). This force is known as action. The table exerts an upward forc

The average distance of an electron in an atom from its nucleus is of the order of: (1) 10 6 m (2) 10 -6 m (3) 10 -10 m (4)10 -15 m Ans: (3) 10 -10 m
Displacement related with a wave is given by y (x, t) = 0.1 cos(0.2x-2t). Where x y are in cm and ‘t' in second. Determine the wavelength, amplitude, frequency and velocity.
