Do quasars reside within or without side of galaxies?

Physics
1 answer:
sveticcg [70]3 years ago
6 0

They almost entirely reside within galaxies because quasars are a subset of blackholes with a large and fast enough accretion disk to generate a beam of interstellar material perpendicular to itself. This typically only occurs in the largest black holes at the center of galaxies (supermassive blackholes) or at least stellar black holes---which still occur within galaxies because the material is necessary to form them.

2 kids are running down the hall at 2 m/s, one is 40kg and the other is 50kg (p=ma)
Georgia [21]

The net force acting on the two (2) kids is equal to 180 Newton.

<u>Given the following data:</u>

  • Mass of kid 1 = 40 kilogram.
  • Mass of kid 2 = 50 kilogram.
  • Acceleration = 2 m/s^2

To determine the net force acting on the two (2) kids:

First of all, we would calculate the total mass of the two (2) kids:

Total\;mass = 50+40

Total mass = 90 kg.

<h3>How to calculate net force.</h3>

In this exercise, you're required to calculate the magnitude of the net force that is acting on these two (2) kids running down the hall. Thus, we would apply Newton's Second Law of Motion.

Mathematically, Newton's Second Law of Motion is given by this formula;

Net\;force = mass \times acceleration

Substituting the given parameters into the formula, we have;

Net\;force = 90 \times 2

Net force = 180 Newton.

diamong [38]

Answer

speed of the molecules

s₁ = v t

when velocity is doubled

s₂ = (2 v)t

   = 2 s₁

they will hit the wall of container two times as often.

the momentum of molecule

p₁ = mvr

p₂ = m(2v)r = 2(mvr)

    = 2 p₁

the momentum change is two times as great.

force is change in momentum

Δp = F(Δt)

mv-(-mv) = 2 mv

F = \dfrac{2 mv}{\Delta t}

F α v

therefore average force impart to the wall on each collision is two times

p = \dfrac{F_{total}}{A}

p = \dfrac{Nmv^2}{3LA}

p α v²

here the velocity is doubled it means pressure becomes four times.
