How fast does the earth fly around the sun?

about 30 kilometers per second

At what speed does the Earth move around the Sun? (Beginner) Short version: Earth's average orbital speed is about 30 kilometers per second. In other units, that's about 19 miles per second, or 67,000 miles per hour, or 110,000 kilometers per hour (110 million meters per hour).

Hope This Helps!     Have A Nice Day!!

The earth moves around the sun at about 30 kilometers per second

The motion of Earth is very fast. It spins or we can say rotates at a speed of about 1,000 miles 1600 kilometers per hour and orbits around the Sun at a speed of about 67,000 miles, 107,000 kilometers per hour or simply 30 kilometers per second. We do not feel any of this motion because these speeds are constant and we're all moving with it at the same constant speed.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
