It will be
E = mgh.
where h and g are constant thus
m can be written as 4/3πr^3*density
E = 4/3πr^3* density
E? = 4/3π(2R)^3* density
= 4/3π8r^3
thus the e will be 4/3π8r^3* density/4/3πr^3*density nd thus you get 8E ..
Assuming that you mean to ask <em>. . . "What is 7.4 </em><u><em>as a fraction</em></u><em> in simplest form</em>?"
7.4 = 7 and 4/10
4/10 can be reduced to 2/5
7 represents = (7*5)/5 = 35/5
so . . 7 + 4/10 = 35/5 + 2/5 = 37/5 (improper fraction in simplest form)
or
. . . . 7 + 4/10 = 7 2/5 (mixed fraction in simplest form)
Well, the length of every day is 24 hours all over the world.
You must be talking about the length of daylight.
On the equator, the longest daylight (sun up in the sky) is just about
12 hours, twice a year, around March 21 and September 21.
At the north and south poles, the sun is up in the sky for SIX MONTHS.
Astronomers have come to the conclusion that quasars are exceptionally strong and compact sources of energy in the centers of distant galaxies after decades of observation.
<h3>Describe quasar.</h3>
A supermassive black hole consuming gas at the heart of a far-off galaxy is known as a quasar. Quasar, which stands for quasi-stellar radio source, was initially identified by astronomers in 1963 as objects that resembled stars but sent forth radio waves instead.
<h3>A quasar is it visible from Earth?</h3>
Although quasars are the most luminous objects in the known cosmos, they seem feeble when viewed from Earth yet are detectable at great distances. The brightest quasar in the sky is 3C 273, which is located in the Virgo constellation.
<h3>does exist quasars today?</h3>
Since quasars are a particular category of Active Galactic Nucleus (AGN), we won't locate any in our neighborhood's few million light years.
