<h2>Answer 1)</h2>

<u>In the given options </u><u>Io is not a dwarf planet</u>

<h2>Explanation: </h2>

Jupiter's moon Io is a volcanically active body in the Solar System, with hundreds of volcanoes, in which some erupting lava fountains dozens of miles high. Io is situated between Jupiter's massive gravity and the smaller but precisely timed pulls from two neighboring moons Europa and Ganymede that orbit farther from Jupiter.

<h2>Answer 2) </h2>

<u>The answer is </u><u>C) Spiral, elliptical, irregular</u>

<h2>Explanation: </h2>

There are three main types of galaxies. Elliptical, Spiral, and Irregular. Elliptical galaxies are shaped like a spheriod, or elongated sphere.  These galaxies have no particular axis of rotation.  Then spiral galaxies consist of a flat, rotating disk containing stars, gas and dust, and a central concentration of stars known as the bulge. The last one An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy.  

<h2>Answer 3)  </h2>

<u>The correct answer is </u><u>D) Waves and particles</u>

<h2>Explanation:</h2>

An important fact about light is that light travels and behaves as waves when it passes through empty space or a vacuum. Light also has the character of a particle, but there are not more experiments about light as a particle in space because light has slightly slower speeds when it travels through denser material such as a planet's atmosphere or a piece of glass.

<h2>Answer 4) </h2>

<u>The correct answer is </u><u>White Dwarf</u>

<h2>Explanation: </h2>

A white dwarf is a small very dense star that is typically the size of a planet. A white dwarf is formed when a low-mass star has exhausted all its central nuclear fuel and lost its outer layers as a planetary nebula. A white dwarf is very dense: its mass is comparable to that of the Sun, while its volume is comparable to that of Earth. And they are located in the lower left of the H-R diagram because they are hot but not very bright

<h2> Answer 5</h2>

<u>The answer is </u><u>D) By using the celestial sphere and constellations</u>

<h2>Explanation: </h2>

There are many ways that scientists use to find the exact location of stars but the most common method to find  the position of objects in the sky is by using coordinates. The easiest way to do this is to use coordinate systems which assume that all objects in space are at the same distance, on the inside of an imaginary celestial sphere. The celestial sphere is an imaginary sphere of gigantic radius with the earth located at its center.

1 io is a moon not a planet.
2)C,The Milky Way is a spiral galaxy
3)D,this is called the particle wave duality,stuff can act like particles and waves at the same time.
4)the white dwarfs
5)using distance and compass direction(I’m not sure about this one though)

Vaselesa [24]

During a total solar eclipse, the moon passes between Earth and the sun. This completely blocks out the sun’s light. However, the moon is about 400 times smaller than the sun. How can it block all of that light?

How does the mass affect the speed as it rolls down a slope?
VikaD [51]
As we use the Kinetic energy and the equation is 1/2mv^2, changing its mass will change its speed and its energy. So more mass, more speed more energy. also the gravitational potential energy; mass x gravity x height; more mass and more height more speed as it go down to the slope! Hope it helps!

an object of mass m is traveling at constant speed v in a circular path of radius r. how much work is done by the centripetal fo
vlada-n [284]

The work done is by the centripetal force on mass m during an angular displacement of 2π revolutions mv²2π /r J

Centripetal force - a force acts on an moving object in circular path.

the centripetal force is given by

F= mv²/r       (equation1)

Work done is given by

W = Fd          (equation 2)

d = 2π

work is done by the centripetal force on mass m during an angular displacement of 2π revolutions is given by:

to calculate work done using equation 1 in 2  we get

W = mv² d/r

 W = mv² × 2π /r J

The work done is by the centripetal force on mass m during an angular displacement of 2π revolutions mv²2π /r J
