Question

summative assesement_2.

subject: physical science

1.if a body is moving with constant speed the average speed of a body will be..........
.2.Two persons weigh 50kg and 64 kg started running in a running field .who has more inertia?
3.relation between momentum and inertia
4.what is spectrum?
5.difference between angular velocity and angular momentum..

I want all answers.......spam answers will be reported​

Answer 1

Answer:

1. average speed will be zero

2.mass is more inertia is more so,

64 kg

3. Inertia describes an object resistance in change of motion whereas momentum is the product of mass and velocity of object.

4. Spectrum is the arrangement of uv visible and infrared wavelengths of light.

5. Angular velocity is the rate of change of angular displacement in unit time whereas

Angular momentum is the product of moment of inertia and angular velocity.

May be it helps if it plzzz mark it brainliest......
