while the gas is detected with X-ray telescopes, that's how we get to know that galaxy clusters contain a lot of mass in the form of hot gas that fills spaces between individual galaxies
The galaxy may be a gravitationally bound substance, ordinarily comprising dark matter, gas, dust, and stars. Galaxies populate the Universe, primarily residing in groups and clusters. Most galaxies have an add up to mass between ~ 107 M⊙ and 1012 M⊙. The galaxies within the Universe are always changing – through secular advancement, mergers, and interactions. An X-ray telescope may be a telescope that's outlined to observe farther objects within the X-ray spectrum. The fundamental components of the telescope are the optics ( collimating), which collects the radiation entering the telescope, and the detector, on which the radiation is collected and measured. An assortment of different plans and advances have been utilized for these elements.

A meteor is the flash of light that we see in the night sky when a small chunk of interplanetary debris burns up as it passes through our atmosphere. "Meteor" refers to the flash of light caused by the debris, not the debris itself.
If any part of a meteoroid survives the fall through the atmosphere and lands on Earth, it is called a meteorite.
Answer:
10 m/s
Explanation:
Kinetic energy= 
mv² where m is mass and v is velocity.
We have to make v the subject so we should rearrange the equation
K=mv²
v²= 
(use algebra)
v²= 7/0.5×0.140
v²=100
v=√100
v=10 m/s
We can confirm this by using the kinetic energy formula.
K=×0.140×10²
K= 7 J
Hence it is proved that velocity is 10 m/s
