Express the number appearing in the following statements in standard form Speed of light in vacuum is 300,000,000 m//s .

In these question, a statement of assertion followed by a statement of reason is given .Choose the correct answer out of the following choices: Assertion and reason both are correct statements and reason is correct explanation for assertion. Assertion and reason both are correct statements but reason is not correct explanation for assertion. Assertion is correct statement but reason is wrong statement. Assertion is wrong statement but reason is correct statement. Assertion: The flash of lightning is seen before the sound of thunder is heard. Reason: Speed of sound is greater than speed of light.

Explain clearly, with examples, the distinction between :- magnitude of average velocity over an interval of time, and the average speed over the same interval. [Average speed of a particle over an interval of time is defined as the total path length divided by the time interval]. Show in both (a) and (b) that the second quantity is either greater than or equal to the first. When is the equality sign true ? [For simplicity, consider one-dimensional motion only].

A sphere of charge + Q is fixed in position. A smaller sphere of charge + q is placed near the larger sphere and released from rest. The small sphere will move away from the large sphere with decreasing velocity an inreasing acceleration, decreasing velocity and increasing acceleration, decreasing velocity and constant acceleration, increasing velocity and increasing acceleration explain, which of the following statements is correct?
