**One more question:**

**What is meant by the term frame of reference? Prove that all the laws of mechanics are the same for all the inertial frame of references. (Chapter 17) (Model Question Paper, 2017)**

Answer Key (Assignment: Chapter 14 Numerical Problems)

If you find any answer is provided wrong then let me know… And haan exponents ki mistake ho to usko khud dekh liye ga… Wo solve karty hue by mistake hojati hai

- cannot be replaced by a single equivalent force
- less force is needed by the user
- remain in the spacecraft
- the height and the time of fall
- the total K.E after impact is
- The total energy of the ball is constant throughtout the motion
- Polarization
- The limiting friction is less than the required centripetal force
- Longitudinal and Stationary
- Wavelength of sound is greater than that of light waves
- The amplitude of oscillations gradually decreases
- produce the state of stable equilibrium
- a monochromatic source of red light be used
- very short focal length and converging properties
- has a definite quality
- it is constant but not zero

Make a checklist for these questions, so you may have an idea that how much you have prepared till now.
