How does gravity cause the solar system to move within the galaxy?
Gravity causes the solar system to move within the galaxy without any
issues and it is known as the strong bond that holds together entire galaxies
which includes the sun, moon, planets etc.
This keeps the planet revolving around the sun and ensures there is no
deviation from the line followed from the onset. If there is a deviation and
planets end up crashing into one another then the result will be very
disastrous and would lead to mass loss of lives.
Gravity also ensures that different planets and countries have a very different
type of climate due to the relative exposure of the planets/areas to the sun.

The graph represents the percentages of salt water and fresh water on Earth. What is the percentage of salt water?
1. 3 percent
2. 50 percent
3. 97 percent
4. 100 percent
Answer:
97.
Explanation:
Though the exact number is 96.5, we can round it up since its 5. When rounding by 10, 5 or more rounds up and 4 or less rounds down. So rounding up of 96.5 is 97. 3)
The percentage of salt water is 97 percent on Earth. Hence, option (3) is correct.
What is water distribution on Earth?Saline seawater makes up the majority of the water in the atmosphere and on the surface of the Earth, with fresh water making up less than 1% of the total. The majority of the water on Earth is saline or salt water, with an average salinity of 35 ‰ (or 3.5%, or around 34 grams of salts in 1 kg of saltwater), though this fluctuates slightly depending on the amount of runoff absorbed from nearby land.
Over 97% of the water on Earth comes from the oceans and marginal seas, saline groundwater, and water from saline closed lakes, however no closed lake holds a large amount of water on a global scale. Except when evaluating water quality in arid places, saline groundwater is rarely taken into account.

Consider going around a horizontal turn to the right. If the coaster suddenly slipped off the track, what path would it follow? Draw a top-view sketch below.
Answer:
Explanation: It would go straight because objects in motion stay in motion and it would stay the same direction
Consider going around a horizontal turn to the right. If the coaster suddenly slipped off the track, It would go straight because objects in motion stay in motion and it would stay the same direction.
What is motion ?"Movement of any object from one position to another position with respect to the observer is called as Motion."
Motion is change of location or position of an object with respect to time. Change in motion is the result of an applied force. Motion is typically described in terms of velocity also seen as speed, acceleration, displacement, and time.

15. Astronomers use different types of telescopes to observe different parts of the
electromagnetic spectrum. This allows astronomers to study objects in space. Some
electromagnetic waves are blocked by Earth's atmosphere, making it difficult for
astronomers to focus the energy into a viewable image. Instead of actually viewing
the energy, astronomers have learned to view the interactions of the energy with
the atmosphere. These faint interactions with the atmosphere allow them to study
highly energetic objects such as pulsars and black holes.
If the waves that are being observed have a frequency of 1022, what type of wave is

What is an electromagnetic spectrum?The complete range of electromagnetic radiation, classified by frequency or wavelength. Despite the fact that all electromagnetic waves have a wide range of frequencies, wavelengths, and photon energies, they all move at the speed of light in a vacuum.
The range of all electromagnetic radiation is represented by the electromagnetic spectrum, which also includes numerous subranges, also known as portions, such as visible light and ultraviolet radiation.
The various parts have different names based on variations in the emission, transmission, and absorption of the corresponding waves as well as on the various practical uses for which they are put to use.
At the frequency of 1022, the wave observed will be a radio wave.
