Is it possible that your cycle has a southward velocity but northward acceleration?If yes,give an example.

Is it possible that the velocity of an object be in a direction other than the direction of acceleration?If yes,give an example.

Is it possible to have the rate of change of velocity constant while the velocity itself changes both in magnitude and direction.If yes,give an example.

A quantity has both magnitude and direction. Is it necessarily a vector? Give an example.

Acceleration is defined as the rate of change of velocity. Is it possible for a body to have acceleration without velocity?Explain.

List various types of isomerism possible. for coordination compounds, giving an example of each.

"The graphical method of adding vectors helps us in visualizing the vectors and the resultant vector.But, sometimes, it is tedious and has limited accuracy." a)Name the alternative method of vector addition. b)Write a mathematical expression to find resultant of two vectors. c)A particle is moving eastward with a velocity of 5m/s .If in 10s ,the velocity changes by 5m/s northwards,what is the average acceleration in this time.
