Question

Answer the following questions fast please tomorrow there is my exam 1) 2 difference between distance and displacement. 2) 1 difference between uniform motion and non uniform motion. 3) examples of mono-atomic and diatomic molecular state.4) how will the compounds,MgCl2 and CaO be formed their elements? 5) If there mass of a moving body is doubled,how many times will the kinetic energy increase?

Answer 1

Here is the answer of your 1st question...
Actual path covered by an object is known as its distance.Distance is a scaler quantity.
The shortest distance between initial and final position of a moving object is called its displacement.Displacement is a vector quantity.


Now,the answer of your 2nd question....
Wheb an object covers equal distance in equal interval of time then the motion is called uniform motion.
When an object covers unequal distance in equal interval of time then the motion is called non- uniform motion.
