INELASTIC COLLISION:
"The collision in which total momentum is preserved but total K.E of system is not conserved is known as inelastic collision".
It is to be noted that momentum and total Energy are conserved in all types of collision. However K.E is conserved only in elastic collisions.
Suppose you sound a 1056-Hz tuning fork at the same time you strike a note on the piano and hear 2 beats/second. You tighten the piano string very slightly and now hear 3 beats/s
The real length of path traversed by a body in a sub interval of time is called as distance. It is the real path travelled by an object among its final and initial positions. It is
When a metal becomes a superconductor, there is a tremendous decrease in it's: a) Total volume b) Electrical resistance c) Length d) Density Ans: While a
Q. An aircraft having awing span of 10 m flies at a speed of 720 kmph. If the vertical component of the earth's magnetic field is 3 X 10 -5 T, calculate the emf induced between th
a closed organ pipe resonates with frequency 6hz and an open organ pipe resonates with frequency 12Hz. if the two organ pipes are joined to form a single organ pipe then it will re
There are imaginary lines or path of the field in the given direction. The lines of force are assumed to make a closed path beginning from N pole and ending at S pole with no loss.
This is due to the surface tension of water. Because of the surface tension , the drop tends to have minimum possible surface area, and the shape which is possible with minimum su

Two bodies are moving in circular paths of equivalent radii. If the speed of the first body is twice that of the second, the centripetal acceleration of the first body is how
The greatest and least magnitude of the resultant of two forces of constant magnitude are P & Q. Proof that when the forces act at an angle of 2 alpha, their resultant is of magnit
