Answer:
In a vacuum all light travels the same speed no matter what the wavelength or frequency. Gamma radiation has a smaller wavelength and larger frequency, radio waves a smaller frequency and larger wavelength.
Explanation:
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.

Answer:
The center of mass move with the velocity of -3.487 m/s.
Explanation:
Given values of block A.
Mass of block A, (M1) = 4 kg
Speed of block A, (V1) = 2 m/s
Given values of block B.
Mass of block B, (M2) = 8.4 kg
Speed of block B, (V2) = -6.1 m/s
Below is the formula to find the velocity of center of mass.
T=distance over speed
T=40m over 9.8ms
