Question

2) Cannot be an inertial frame because the earth is revolving around the sun​

Answer 1

Answer:

The answer to your question is:-

Earth can not be a inertial frame of reference because it is revolving around the sun and also on its own axis. and a accelerated object can't be taken as inertial frame of reference. and a reference frame attached to an non-inertial frame also can't be taken as inertial frame of reference.
