The fastest man can run 100 meters in 10 seconds. What is his speed in miles per hour?

Answers

Answer:22.37 mph

Explanation:

100 meters = 0.062137 miles

Assume constant speed over the distance.

0.062137 miles in 10 sec

0.372822 miles in 60 sec = 1 minute

22.36932 miles in 60 minutes

22.37 mph rounded to 2 decimals

22.37 , or 36 kilometers an hour

Explain how CMB is observed on the Earth?

Answers

Answer:

the speed of light (all photons, naturally including those from the CMB, travel at the speed of light relative to you, regardless of frame or your velocity).

But I suspect you’ve asked this question because of a totally understandable but not quite correct set of assumptions about the universe. If my hunch is correct, you understand the CMB a bit like the skin of a balloon, gradually expanding over time. The Earth is a point somewhere in this balloon, and you’re asking about the Earth’s velocity relative to perhaps the center of this balloon. But that’s not quite how the universe works. It’s far more strange.

Our best hypothesis thus far is that the Big Bang happened from a single point. The “space” around us IS that single point. There is no origin point, since everywhere is by definition the origin point. You can see this for yourself by noticing that basically every star and galaxy we can see is - in the long run - moving away from us. And this is true regardless of whether you are on Earth or another star, or any point in the universe. So from this, it doesn’t really make sense to ask what the velocity of the earth is relative to the CMB rest frame, because space itself is expanding. Hopefully haven’t caused too many headaches!

what phenomenon is the basis behind the ability to separate miscible liquids by distillation?

Answers

The basis of the separation by steam distillation is that while the water and organic condensed phases are immiscible, the vapors of both are miscible. Once condensed, the two separate again allowing for an easy separation. As noted above, both liquids and solids can be distilled by steam.

Which color of light has the highest energy?

answer for c plsssssss

Answers

Answer:

D has 18 electrons (since atomic number = protons = electrons)  

[Ne]3s² 3p⁶   (spdf electron configuration)2, 8, 8             (basic electron configuration) Argon            

E has 20 electrons    

[Ar]4s²         (spdf electron configuration)2, 8, 8, 2      (basic electron configuration)Calcium

Explanation:

In spdf form, we are basically spreading out the total number of electrons over the different spdf orbitals. While doing this we have to remember that an s-orbital holds 2 electrons max, a p-orbital holds 6 electrons max, a d-orbital holds 10 electrons max, and an f-orbital holds 14 electrons max.

Based on energy levels, the orbitals are filled in the following order:

1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, and 7p

So for example Argon with 18 electrons would be filled in the following way:  

1s², 2s², 2p⁶, 3s², 3p⁶.

This can be abbreviated using the configuration of the previous Noble gas for example [Ne] = 1s², 2s², 2p⁶

∴ we can express Argon as [Ne] 3s², 3p⁶.

in order for a substance to be an effective mobile phase in a chromatography experiment, it must be able to move

Answers

In order for a substance to be an effective mobile phase in a chromatography experiment, it must be able to move different components of a mixture at different rates.

Chromatography involves the separation of substances using the application of the solubility differences in them. It has two phases known as the stationary and mobile phases.

The mobile phase involves motion which is why the ability of substances to move at different rates is a great factor in this type of phase. The Stationary phase on the other hand doesn't involve movement of substances.
