<h3><u>Answer;</u></h3>

D. Dark spot

<h3><u>Explanation;</u></h3>
  • <em><u>The parts of a star includes the core, radiative and convective zones, photosphere, chromosphere and corona.</u></em>
  • <em><u>Corona is the outermost part of the star that extends for million miles into the space.</u></em>
  • <em><u>Photosphere is a part of the star outside the stellar zones, where visible light is emitted.</u></em>
  • <em><u>Radiative zone is a layer of the star outside the core where energy is transported by radiation. </u></em>
  • <em><u>Chromosphere is a layer outside photosphere. In the sun this layer is red colored from an abundance of hydrogen gas.</u></em>
  • <em><u>Therefore, in our question, Dark matter is not a layer or a part of a star. </u></em>

What is the mechanical advantage of a nail puller where you exert a force 45 cm from the pivot and the nail is 1.8 cm on the oth
Mandarinka [93]

Answer:

Explanation:

Mechanical Advantage is the ratio of the distance of the input load (Li)from the pivot to the output load applied to the pivot(Lo)

MA = Li/Le

Given;

Li = 45cm

Lo = 1.8cm

MA = 45/1.8

MA = 25

Hence the mechanical advantage is 25

Also MA is expressed in terms of the force ratio which is the ratio of the Load to the effort applied.

MA = Load/Effort

Given

Load = 1250N

MA = 25

Effort = ?

Substitute

25 = 1250/Effort

Effort = 1250/25

Effort = 50N

Hence the minimum force exerted on the load is 50N

What do astronomers mean by light pollution?
Margarita [4]

Answer:

a. Light pollution refers to light used for human activities that brightens the sky and hinders astronomical observations.

Explanation:

Light pollution is due to the excessive and misdirected use of artificial light. Light bulbs are often design in an incorrect way, since a great part of its light is not completely directed to the ground and an important percentage is emitted to the sky in where will be scattered and reflected back to ground by the particles in the atmosphere. That brings as an effect a sky glow, therefore the visibility of astronomical objects will be extremely reduce.  

Hence, professional astronomical research and amateur observations will be affected. Light pollution has a negative impact on bird migration at night and in the health of difference species, humans also.

Does the inertia of an object change as the object’s velocity changes explain
Sever21 [200]
Inertia is proportional to mass. It is a measure of the resistance to changes in velocity. Inertia is a property of mass and cannot change. Momentum changes as an object changes its velocity. Good luck on your assignment and have a great day! :D

A 90-kilogram physics student would weigh 2970 Newtons on the surface of planet X. What is the magnitude of the acceleration due
KiRa [710]
<u>Weight = (mass) x (acceleration of gravity)</u>

Divide each side by (mass),and we have

                     Acceleration of gravity = (weight) / (mass)

Acceleration of gravity = 2,970/90 = 33 newtons per kilogram = <em>33 m/s²</em>
