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.

A solenoid inductor has an emf of 0.80 V when the current through it changes at the rate 10.0 A/s. A steady current of 0.20 A pr

barxatty [35]

Answer:

The number of turns of the inductor is 2000 turns.

Explanation:

Given;

emf of the inductor, E = 0.8 V

the rate of change of current with time, dI/dt = 10 A/s

steady current in the solenoid, I = 0.2 A

flux per turn, Ф = 8.0 μWb per

Determine the inductance of the solenoid, L

E = L(dI/dt)

L = E / (dI/dt)

L = 0.8 / (10)

L = 0.08 H

The inductance of the solenoid is given by;

$L = \frac{\mu_o N^2 A}{l}$

Also, the magnetic field of the solenoid is given by;

$B = \frac{\mu_o NI}{l}$

I is 0.2 A

$B = \frac{\mu_oN(0.2)}{l} = \frac{0.2\mu_o N}{l}$

$\frac{B}{0.2 } = \frac{\mu_o N}{l}$

$L = \frac{\mu_o N^2 A}{l} \\\\L = \frac{\mu_o N }{l} (NA)\\\\L = \frac{B}{0.2} (NA)\\\\L = \frac{BA}{0.2} (N)$

But Ф = BA

$L = \frac{\phi N}{0.2} \\\\\phi N = 0.2 L\\\\N = \frac{0.2 L}{\phi} \\\\N = \frac{0.2 *0.08}{8*10^{-6}}\\\\N = 2000 \ turns$

Therefore, the number of turns of the inductor is 2000 turns.

With an increase in temperature, the viscosity of liquids will: . (a) decrease (b) increase . (c) no change

ICE Princess25 [194]

Answer:

(a) decrease

Explanation:

Viscosity is the resistance which occur to flow of the fluid.

More the inter molecular forces between particles of the liquid, more the viscosity of liquid.

<u>Effect of temperature on viscosity:-</u>

Viscosity decreases with the increase in the temperature as forces among the particles decrease on increasing temperature. The kinetic energy of the particles of the liquid increases causing to move in more random motions and thus weaker inter molecular forces and this offer less resistance to the flow.

<u>Hence, viscosity of the liquids decrease with the increasing temperature.</u>
