How do we know that galaxy clusters contain a lot of mass in the form of hot gas that fills spaces between individual galaxies?.
Olin [163]

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.

Which of the following statements concerning the nuclear force is false? O The nuclear force is attractive and not repulsive. O
Ulleksa [173]

Answer:

  • The nuclear force is attractive and not repulsive.
  • The nuclear force is very weak and much smaller in relative magnitude than the electrostatic and gravitational forces.

Explanation:

  • Nuclear force is the strongest existing force in the nature.
  • It has the shortest range.
  • Its main function is to hold the subatomic particles together in nature.
  • The nuclear force is created  by the exchange of pi mesons between the nucleons of an atom, but for this exchange to happen the particles must be close to one another of the order of few femtometer.
  • At about 1 femtometer the nuclear force is very strongly attractive in nature but at distance greater than 2.5 femtometer it fades away.
  • The force becomes repulsive in nature at distance less than 0.7 femtometer.
  • This force holds the likely charged protons together in the nucleus.

A mass attached to the end of a spring is oscillating with a period of 2.25 s on a horizontal frictionless surface. The mass was
Rudiy27

Answer:

X=0.0389m

Explanation:

From the question we are told that:

Period of spring T_s=2.25s

Initial Position of Mass x=0.0480m

Final Mass period T_f=5.85s

Generally the equation for the Mass location is mathematically given by

X=xcos*\frac{2\pi T_s}{T_f}

X=0.048*cos*\frac{2\pi 5.85}{2.25}

X=0.0389m

Is the distance a baseball travels in the air after being hit distance a baseball travels in the air after being hit a discrete
Nookie1986 [14]

Answer:

Continuous random variable

Explanation:

The distance that baseball travels after being hit is a random variable and it assume any real value defined on the sample space.

The distance is measurable and thus is continuous random variable because continuous variable cannot be counted but could be measured.
