List all the planets in the solar system and their features

Answer:

The planets of the solar system are 8:

Mercury is the planet closest to the sun, and therefore the hottest planet in stable conditions. It has an average temperature of 160º C, but with nights of up to -170º C. It is a rocky planet, and it does not have satellites. Its period of rotation around the sun is 88 days.

Venus is also a rocky planet, but considerably larger than Mercury. It has an average temperature of 460º C, due to its enormous atmospheric pressure, thus surpassing Mercury, which is even closer to the sun. Its rotation period is 225 days, and it does not have satellites either.

The Earth, our planet, is the only one with ideal conditions for the development of life: it has a rotation of 365 days, an average temperature of 15ºC and water in sufficient abundance to allow the development of oxygen-producing vegetation.

Mars, the last rocky planet in the chain, has a rotation period of 687 days, an average temperature of -46º C and minimal amounts of water. It has 2 satellites.

Then we have the gaseous planets, which are Jupiter, Saturn, Uranus, and Neptune. These do not have a solid surface, but are composed of gases (and portions of ice due to the extremely high temperature they have, from -120ºC to -220ºC) and enormous amounts of satellites. These are the least fit for life, due to their temperature and lack of solidity.

Answer:

Look below.

Explanation:

Mercury is the closest planet to the sun. It rotates slowly — about twice for every three orbits it completes. Slightly larger than Earth's moon, it is the smallest planet in the solar system. It has no moons, no rings, and an atmosphere so thin that scientists classify it as an exosphere.

The second planet from the sun, Venus is slightly smaller than Earth.The heat and pressure make the planet decidedly inhospitable to life.

Earth, the third planet from the sun and the largest terrestrial planet, is the only planet known to host living beings and the only one known to have liquid water on its surface. The atmosphere, made of mostly nitrogen, oxygen and carbon dioxide, is crucial to Earth's ability to support life.

Mars, the fourth planet from the sun.The red color of the surface comes from iron oxide or rust in the soil. The topography is characterized by large volcanoes and deep valleys, and Mars experiences frequent planet-wide wind storms. Some of the surface features of Mars, such as dry river beds, hint to the possibility that water previously existed on the planet and may still flow under the surface.

 Jupiter

Jupiter is the largest planet in our solar system

Jupiter's mass is 318 times greater than Earth's.  Jupiter’s magnetic field is 20,000 times stronger than Earth’s and it has the strongest radio emissions of any planet in the solar system. as of April 2011 has 63 known moons in orbit around it, the largest of which are Io, Europa, Ganymede and Calliso.

Saturn, the sixth planet from the sun, is also a gas giant, and it's most impressive feature as seen from afar is an extensive and complex ring system. The rings orbit the planet in a thin band about a mile thick. The radius of Saturn is about 9.5 times that of Earth, and instead of one paltry moon, it boasts 62. The interior of Saturn, like Jupiter, is made of mostly hydrogen and helium. Nearing the core, the intense pressure turns the gases into liquids and ultimately into a metallic form that conducts electricity.

While most planets spin on their axis with a slight tilt, the ice giant Uranus spins on an axis parallel to its orbit. With a diameter of 31,518 miles (50,723 kilometers), this cold planet is four times the size of Earth and is made of a large atmosphere of methane with a dense core of frozen methane. Uranus has a faint ring system and 27 moons in its orbit.

The blue planet Neptune is the farthest one from the sun and, like Uranus, is a very cold place.  one year on Neptune is 165 Earth years. The atmosphere is mostly methane, which gives the planet its blue color. The cold interior of the planet is mainly methane ice. Like all the outer planets, Neptune, like Uranus, has a diameter roughly four times that of Earth. Thirteen moons and a faint ring system orbit the planet.

Saturn

Saturn has 53 named satellites

Saturn has the lowest density of any planet in our solar system. It has a rocky core composed of liquid metallic hydrogen and elements consistent with the primordial solar nebula (gaseous cloud) that formed the solar system. Saturn’s most prominent feature is its rings, first observed by Galileo in 1610. The rings are composed of millions of small particles of rock and ice, each having its own independent orbit around the planet. Although the other gas planets also have rings, it is not yet known why Saturn’s are so prominent.

Uranus

Uranus is the only gas giant with its equator at a right angle to its orbit. It was also the first planet to be discovered through a telescope. It has 13 known rings that are dark and composed of dust and particles up to 10 meters in diameter. Uranus has 5 large moons as well as 10 smaller ones that were discovered by the Voyager 2 probe. The methane in Uranus’s upper atmosphere is what gives the planet its blue color.

Neptune

Neptune’s existence was the first to be predicted by mathematical calculations before the planet was actually seen. Neptune's mass is approximately 17 times greater than Earth’s. Its winds can reach up to 2,000 km per hour, the fastest in the solar system.

a typical cmall flashlight contains two batteries each having na emf of 2.0 v connected in series with a bulb havin ga resistanc
Helen [10]

Answer:

P = 0.25 W

Explanation:

Given that,

The emf of the battry, E = 2 V

The resistance of a bulb, R = 16 ohms

We need to find the power delivered to the bulb. We know that, the formula for the power delivered is given by :

P=\dfrac{V^2}{R}\\\\P=\dfrac{2^2}{16}\\\\=0.25\ W

So, 0.25 W power is delivered to the bulb.

When figure skating how do you quickly transition from backwards to forwards without falling or just going in a circle? I'm fair
olga2289 [7]
I am a competitive figure skater.  There are certain turns you can use such as a mowhawk, where you set one foot down that is facing the opposite direction from which you are gliding.  There is a two foot turn, where you either go on or toes and turn backwards, or lean somewhat on your heals and turn forwards.  Use your hips to help turn.  And a 3 turn, which is basically a 2 foot turn on 1 foot.  But remember, it takes practice, and you may fall a couple times.

State the term used to describe the turning force exerted by the man
ozzi

]A force called the effort force is applied at one point on the lever in order to move an object, known as the resistance force, located at some other point on the lever.

The way levers work is by multiplying the effort exerted by the user. Specifically, to lift and balance an object, the effort force the user applies multiplied by its distance to the fulcrum must equal the load force multiplied by its distance to the fulcrum. Consequently, the greater the distance between the effort force and the fulcrum, the heavier a load can be lifted with the same effort force.
