Answer: linear velocity = 169,745.2mi/hr

Explanation:

Given: radius of orbit= 2,600,000mi

Time taken for orbit = 4.01 days = 4.01 × 24 hrs= 96.24hrs

Linear velocity = distance travelled/time

distance travelled = circumference of orbit = 2πr

= 2π × 2,600,000mi

= 16336281.8mi

Linear velocity = 16336281.8/ 96.24hrs

= 169745.2mi/hr

What happens to electric charges within a conductor when a charged object is brought close to it
Agata [3.3K]
Well, if a charger conductor is touched to another object or close enough to touching the object then the conductor can transfer its charge to that object. Conductors allow for electrons to be transported from particle to particle, so a charged object will always distribute its charge until the repulsive forces are minimized.

Why do stars twinkle​
vlada-n [284]

As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving, the bending of the light changes too, which causes the star's appearance to wobble or twinkle.
