The solar system is bounded together by gravity, and is made up of the Sun  eight planets and dwarf planets

The correct options are;

  • The Sun ⇒ generates energy deep in its core through the fusion of hydrogen and into helium
  • Earth ⇒ has a single moon that is surprisingly large compared to its planet
  • Saturn ⇒ is orbited by at least two geologically active moons: Titan and Enceladus
  • Neptune ⇒ has a large moon, Triton, that almost certainly once orbited the Sun independently
  • Venus ⇒ has a surface hot enough to melt led as a result of extremely strong greenhouse effect
  • Uranus ⇒ has an axis tilt that gives it very extreme seasons
  • Pluto ⇒ was studied up close in 2015 by the New Horizons spacecraft.
  • Mars ⇒has no surface liquid water today, but shows clear evidence of such water in the distant past
  • Jupiter ⇒ has a famous storm known as the Great Red Spot
  • Eris ⇒ is similar in size to Pluto and also considered a dwarf planet
  • Mercury ⇒ has a greater difference in temperature between its day and night sides than any other world

Reasons:

The Sun generates energy by nuclear fusion in its cores

The size of the Moon more than a quarter of the Earth's size

Saturn moon Titan shows signs of volcanic activity

The moon Triton rotates in the opposite direction to the rotation of Neptune

Venus is the second closest planet to the Sun with a thick CO₂ atmosphere, resulting in a greenhouse effect that makes the planet 510°C hotter

Uranus has seasons that last for approximately 20 years

The New Horizons spacecraft took 9.5 years to reach Pluto after the mission was launched in 2006

Mars liquid water disappeared billions of years ago

The Great Red Spot storm has lasted for over 300 year

Eris, one of the largest dwarf planets and is further from the Sun than Pluto

The difference in temperature between the day and night sides of Mercury is 427°C - (-180°C) ≈ 607°C

What is the universe made of?​
RoseWind [281]

Answer:

Composition. The universe is composed almost completely of dark energy, dark matter, and ordinary matter. Other contents are electromagnetic radiation (estimated to constitute from 0.005% to close to 0.01% of the total mass-energy of the universe) and antimatter.

A ball is thrown upward. At a height of 10 meters above the ground, the ball has a potential energy of 50 joules (with the poten
lions [1.4K]

Answer:

 h = 20 m

Explanation:

given.

height, h = 10 m

Potential energy at 10 m = 50 J

Kinetic energy at 10 m = 50 J

maximum height the ball will reach, H = ?

Total energy of the system

T E = 50 J + 50 J

T E = 100 J

now,

A h = 10 m

P E = m g h

50 = m g x 10

mg = 5 ..............(1)

at the top most Point the only Potential energy will be acting on the body.

now, TE = Potential energy

 100 = m g h

5 h = 100

 h = 20 m

hence, the maximum height reached by the ball is equal to 20 m.

Could an<br> average star, such as our<br> sun, become a neutron star?<br> Explain your answer.
larisa86 [58]
<span>No. Neutron stars are the remnants of very large stars that have supernova'd. Anything below 1.44 solar masses becomes a dwarf, anything above 5 solar masses becomes a black hole. Everything in between becomes a neutron star (or quark star, but it's not proven).</span>

Core
Home of atoms of hydrogen also the lightest element in the universe.
Radiative Zone
Outside the inner Core it radiates energy through the process of photon emission.
Convection Layer
Outer most Layer of the Core, it extends form a depth of 200,000 kilometres to the visible surface. Energy is created by Convection. This is where light is produced.
Photosphere
Surrounds the stars and is where light and heat radiate.
Chromosphere
Reddish gas layer outside of the photosphere I think it also works with the Corona.
Corona
Aura of Plasma that surrounds the Sun and other stars, it extends millions of kilometres and easily seen during a total eclipse.

A certain type of laser emits light that has a frequency of 4.2 × 1014 Hz. The light, however, occurs as a series of short pulse
bogdanovich [222]

Explanation:

It is given that,

Frequency of the laser light, f=4.2\times 10^{14}\ Hz

Time, t=3.2\times 10^{-11}\ s

(a) Let \lambda is the wavelength of this light. It can be calculated as :

\lambda=\dfrac{c}{f}

\lambda=\dfrac{3\times 10^8}{4.2\times 10^{14}}

\lambda=7.14\times 10^{-7}\ m

or

\lambda=714\ nm

(b) Let n is the number of the wavelengths in one pulse. It can be calculated as :

n=f\times t

n=4.2\times 10^{14}\times 3.2\times 10^{-11}

n = 13440

Hence, this is the required solution.
