That was Johannes Kepler.
He couldn't say why that should happen. But he was able to show that
if we <em><u>assume</u></em> the the sun is in the center of the solar system, and <em><u>assume</u></em>
that the planets revolve around the sun in elliptical orbits, and <em><u>assume</u></em> that
the farther a planet is from the sun the longer it takes to orbit the sun, then
<em>that matches everything that we see the planets actually doing in the sky</em>.
Then Isaac Newton came along, and wrote down a short, simple formula
for the force of gravity. And then he showed that <u>IF</u> his formula for gravity
is correct, then the planets MUST do everything that we see them actually
doing in the sky, and they MUST behave according to Kepler's laws.
Wotta guy !
Answer:
The Earth is in hydrostatic equilibrium pretty much. Which is to say that if it were entirely liquid it would still be the same shape ignoring minor differences like mountain ranges that are in any case indistinguishable on the large scale.
A spinning liquid sphere will flatten out somewhat at the axis poles and expand somewhat in its equatorial region and that’s the way the Earth is.
Hope it wirks
A synthetic element is one of 24 chemical elements that do not occur naturally on Earth: they have been created by human manipulation of fundamental particles in a nuclear reactor, a particle accelerator, or the explosion of an atomic bomb; thus, they are called "synthetic", "artificial", or "man-made". The synthetic elements are those with atomic numbers 95–118, as shown in purple on the accompanying periodic table:[1] these 24 elements were first created between 1944 and 2010. The mechanism for the creation of a synthetic element is to force additional protons onto the nucleus of an element with an atomic number lower than 95. All synthetic elements are unstable, but they decay at a widely varying rate: their half-lives range from 15.6 million years to a few hundred microseconds.
Answer:
The thickness of the oil slick is 
Explanation:
Given that,
Index of refraction = 1.28
Wave length = 500 nm
Order m = 1
We need to calculate the thickness of oil slick
Using formula of thickness
Where, n = Index of refraction
t = thickness
= wavelength
Put the value into the formula
Hence, The thickness of the oil slick is
Answer:
Galileo
Explanation:
Galileo Galilei pioneered the experimental scientific method, and was the first to use a refracting telescope to make important astronomical discoveries. He is often referred to as the "father of modern astronomy" and the "father of modern physics". Albert Einstein called Galileo the "father of modern science."
