Disk of dust and gas contains the new born stars and as well as young stars and the Halo region contains the old stars.

The different regions of a spiral galaxy like our Milky way tend to have characteristic populations of stars.

Halo: The halo tends to have older, red stars. In general, blue stars are larger but since they are also hotter, tend to run through their fuel faster and have shorter lives. Halo stars tend to be older stars, The halo is generally lacking in dust and low in metals.

Bulge: The outer Area of the bulge has mostly older red stars. The inner bulge has active star formation and has a mix of red and blue stars.

Disk: The disk has active star formation regions, so there are young blue stars in that region. Here are the stars that are both old stars and young stars. The blue stars are largely found on the edges of the spiral arms.

Thus disk with the dust clouds contains new and young stars. And halo region contains old stars.

_____ provides heat to flowing magma that forms convection cells.
Zina [86]

Answer:

C

Explanation:

Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle.

Explain how Newton's third law is applied when a rocket ship is being launched?
garri49 [273]

Newton's Third Law states that "every action has an equal and opposite reaction". In a rocket, burning fuel creates a push on the front of the rocket pushing it forward. This creates an equal and opposite push on the exhaust gas backwards.

A runner taking part in the 200 m dash must run around the end of a track that has a circular arc with a radius of curvature of
Dominik [7]

Answer:

The centripetal acceleration of the runner as he runs the curved portion of the track is 0.91 m/s²

Explanation:

Given;

distance traveled in the given time = 200 m

time to cover the distance, t = 29.6 s

speed of the runner, v = d / t

v = 200 / 29.6

v = 6.757 m/s

The centripetal acceleration of the runner is given by;

a_c = \frac{V^2}{r}

where;

r is the radius of the circular arc, given as 50 m

Substitute the givens;

a_c = \frac{V^2}{r}\\\\a_c = \frac{(6.757)^2}{50}\\\\a_c = 0.91 \ m/s^2

Therefore, the centripetal acceleration of the runner as he runs the curved portion of the track is 0.91 m/s².

How much energy (in kJ) do 3.0 moles of photons, all with a wavelength of 670 nm, contain??
aliina [53]
<span>Photon energy is the energy carried by a single photon with a certain wavelength and frequency. These terms are related by an equation. 
E = hv
where h is the Planck's constant (6.626 x 10-34 J s), v is the frequency which is related to the wavelength by:

λv = c where λ is the wavelength and c is the speed of light (3.00 x 108 m/s)

Therefore, the energy equation 
E = hc / λ
E = </span>6.626 x 10^-34 J s (3.00x10^8 m/s) / 670 x10^-9 m
E = 2.966865672x10^-19 J per photon

Total energy = 2.966865672x10^-19 J / photon ( 3.0 mol) ( 6.022x10^23 photon / 1 mol ) = 535993.95 J
