Answer:

Analyze the Characteristics of a Star

Explanation:

Surface Temperature

First, you want to determine the color of the star - this can determine the heat and age of the star.

Second, you want to measure the spectrum and get the spectral type.

Chemical Composition

Determine which lines are present in the spectrum.

Luminosity

Measure the apparent brightness and compensate for distance

Radical Velocity

Measure the Doppler shift in the spectrum.

Rotation

Measure the width of spectral lines.

Mass

Measure the period and radial velocity curves of spectroscopic binary stars.

Diameter

1. Measure the way a star’s light is blocked by the Moon.

2. Measure the light curves and Doppler shifts for eclipsing binary stars.

Answer:

Measuring distances to stars through stellar parallax. Measuring distances to stars through the moving cluster method. Astronomers measure the temperature of a star by looking at the star's color and its spectrum. The apparent brightness of a star tells how bright it seems to us

Aliun [14]

Answer:

Option 3 is correct.

The atomic nucleus of each element has a unique number of protons. Therefore, the energy of the electron layers of the atoms of each element is unique.

If we have the energy released from each electron transfer between the layers of the atom, we can identify the element.

The surface tension of which of the following liquid is maximum?
Elden [556K]
The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension<span>. I think the correct answer is option A. H2O will have the highest surface tension due to the hydrogen bonds that are present. Hope this answers the question. Have a nice day.</span>

Carbonic acid reacts with water to yield bicarbonate ions and hydronium ions: h2co3+h2o?hco3?+h3o+ identify the conjugate acid-b
Levart [38]
Conjugate base pairs are acid and bases having common features. These features are the equal gain or loss of protons of the pairs. Conjugate pairs should always be one base and one acid. One would not exist without the other. Conjugate acids are the substances that gains protons while conjugates bases are those that loses protons. <span>The substances in the equilibrium reaction that is given is identified as follows: 
HCO3^-      +     H2O <----->   CO3^2-          +             H3O^+ 
 acid                   base         conjugate base           conjugate acid 

HCO3^- ion is an intermediate molecule of CO2 and CO3^2-. When we add OH- to HCO3^-, we produce CO3^2-. And when we add H+ to HCO3, we produce CO2. </span>
