According to science, the fastest speed possible for anything is the speed of light. The speed of light is about 186,000 miles p

er second. That means that in one minute, light travels 11,160,000 miles. The star nearest Earth is the Sun. It's about 93,000,000 miles from Earth. Therefore, it takes sunlight about eight minutes to travel to Earth. So, when you see the Sun, you aren't seeing it as it is. You're seeing it as it was eight minutes ago. Since the stars are much farther away than our ...

Yes, yes, go on !  The nearest star to us that's outside of our solar system
is 4.2 light years away.  So when we see that star, we're not seeing it as
it is, we're seeing it as it was 4.2 years ago.  And all of the other stars
are much farther away from us than that one is.  We have detected
galaxies that we're not seeing as they are now, we're seeing them as
they were 13 billion years ago !

The moon is about 240,000 miles away from us.  When we look at the
moon, we're not seeing it as it is, we're seeing it as it was 1.3 seconds ago.

The refrigerator in your kitchen is about 12 feet from you.  So when you
look at the refrigerator, you're not seeing it as it is.  You're seeing it as it
was 0.0000000122 second ago.

It takes TIME for light to travel from one place to another.

What does physics have to do with science and chemistery
Rainbow [258]

Physics is known as the fundamentals of science, as all the branches of science, whether it is biology, chemistry, ecology, botany, environmental science, geology, geography, and more all follow the laws of physics, such as laws of thermodynamics, etc. Chemistry is existent because of physics due to the Conservation of mass. Once you get to a much deeper level of science, you will notice that all the fields of science start to blend together and all add up to one huge painting!

state whether the table represents a relation function both or neither x y 4 -20 1 -17 4 -14 16 5 10 0 -19 -16

state, whether the table represents a relation function both or neither x y 4 -20 1 -17 4 -14 16 5 10 0 -19 -16 Reconstruction was successful in that it allowed the United States to once again function as a single country by 1877. The states' rights vs. federalism controversy, which had been a point of contention since the 1790s, was also eventually resolved during reconstruction.

By most other standards, reconstruction was a failure: radical Republican legislation eventually failed to shield former slaves from white persecution and to bring about significant alterations to the South's socioeconomic structure. The federalism question, which had been a topic since the 1790s practically immediately, was at hand when President Rutherford B. Former Confederate officials and slaves returned to the South after Hayes withdrew federal soldiers from the region in 1877. These newly powerful white southern legislators established anti-progressive laws like voter ID requirements and black codes with the help of a conservative Supreme Court in an effort to roll back the rights that blacks had won during Radical Reconstruction. With its rulings in the Slaughterhouse Cases, the Civil Rights Cases, and United States v., the U.S. Supreme Court strengthened this anti-progressive movement federalism.

Why is a steam burn more damaging than a burn from boiling water at the same temperature?
maksim [4K]
The phase change (from gas to liquid) that the steam undergoes right when it touches your skin releases a lot of energy right onto your skin so it burns a ton. The boiling water would just burn you until it reaches the same temperature as your skin.
