The magnitude of average velocity is equal to the average speed if the motion of an object is along a straight line and in the same direction.
True
can’t predict
sometimes true and sometimes false
False
The answer is True.
Explain clearly, with examples, the distinction between: a) magnitude of displacement (sometimes called distance) over an interval of time, and the total length of path covered by a particle over the same interval; b) 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].
Sometimes, Ionic product and solubility product are the same - true or false?
