Answer:

... because Edwin Hubble was the man that proved it from his observations. He proved that there is a direct relationship between the speeds of distant galaxies and their distances from Earth. This is now known as Hubble's Law.

Answer:

Using the redshift of electromagnetic spectra you can determine the current distance and speed of remote galaxies. Observing the same galaxies over time you can determine that the galaxies are moving away from us and accelerating. You will also note that their speed is proportional to their distance (the further away they are the faster they are moving), which is a feature of metric expansion.

AURORKA [14]

If you draw line segments DF and FG, you can show ΔDEF ≅ ΔGEF by SSS (side-side-side congruence). So, ∠DEF ≅ ∠GEF because corresponding parts of congruent triangles are congruent. Have fun with.. life lol

Incisors (front teeth) act as wedges in the human body. Which change would increase the mechanical advantage of incisors? a decr

Kaylis [27]

Based on the information given about the wedge, the option that will increase the mechanical advantage of incisors is D. an increase in the length of the teeth and no change in the thickness at the widest part of the teeth.

A wedge simply means a triangular shaped tool that's used as a simple machine. It is used for the separation of objects.

It should be noted that Incisors (front teeth) act as wedges in the human body and there can be an increase the mechanical advantage of incisors when there's an increase in the length of the teeth and no change in the thickness at the widest part of the teeth.

AfilCa [17]

These solids, diamond and graphite are first naturally occurring inorganic substances and have an orderly internal structure and characteristic chemical composition, crystal form, and physical properties.

<h3>Standard temperature and pressure of diamond and graphite</h3>

At standard temperature and pressure, the two minerals; diamond and graphite which are both composed of carbon atoms are Allotropes of Carbon. Additionally, peculiar difference between them exists in the delocalization of electrons in one as opposed to the other.
