2.the speed of sound in dry air is ___________
3. unit of momentum in
SI and CGS is______ & ______
4. work =___*___​

Answer 1

Answer:

The speed of light is 3 x 10to power 8 m/sec

Speed of sound in dry air is 343 m/sec

Unit of momentum in s.i system is kg.m/sec and in c.g.s system it is g.cm/sec

work = force x displacement

Answer 2

Answer:

1)the speed of light is 299792458 m/s

2)the speed of sound in dry air is 343m/s

3)unit of momentum in mass and velocity.

4)work:-in kilogram meters per second (kg. m/s)
