How many miles are in 0.062500 light seconds (s)?
MrRa [10]

Answer:

11625 miles

Explanation:

A second of light is the distance that light travels in a second. It has a value of 299792458 kilometers or if we do the unit conversion, 186,000 miles. A mile is 1.609 kilometers

Let's make a rule of three:

1 light s travels a distance of 186000 miles

0.062500 light s would travel a distance of (0.062500 . 186000) = 11625 miles

Why has the atomic theory changed over time?
dalvyx [7]
Well thats because things changed in science. Newtons law of gravity (which was all things that come up must come down) evolved once scientist figured out that in space things float around. Science always evolves weather it's in a year or a day, but if your asking about HOW it evolved, thats something different. Hope I'm helping you!
