What else can I help you with?
Is it possible to see earth in its past using a telescope If we knew a defined 'spot' where the earth was a few millions of years ago could we locate and view it?
That would only be possible if we could travel faster than the speed of light...a lot faster...and then you would have to get farther out than light from earth has traveled in the last million years and then look toward earth..then, in theory, you could see the past.
If a p wave arrives at a seismograph station at 907 am and the S waves arrives at the same seismograph stations at 909 an about how fare is that station from the epicenter of the earthquake?
To estimate the distance from the seismograph station to the earthquake epicenter, we can use the typical speed of P waves (approximately 6 km/s) and S waves (approximately 3.5 km/s). The time difference between the P wave and S wave arrival is 2 minutes (or 120 seconds). Given that P waves travel faster, we can calculate the distance using the time difference, which would be approximately 360 km from the epicenter to the station.
What wave reaches the recording station after an earthquake?
The first wave to reach a recording station after an earthquake is the Primary wave, or P-wave. P-waves are compressional waves that travel faster than other seismic waves, moving through both solid and liquid layers of the Earth. They are followed by Secondary waves (S-waves) and surface waves, which arrive later and can cause more damage.
A seismograph station recorded the arrival of the first P-wave at 7 32 pm From an earthquake that ocvured 4000 kilometers away What time was it at the station when the earthquake occurred?
P-waves, or primary waves, travel faster than other seismic waves, typically at speeds of about 6 to 8 kilometers per second. If the earthquake occurred 4,000 kilometers away and the P-wave arrived at 7:32 PM, it would have taken approximately 500 to 667 seconds (about 8 to 11 minutes) to reach the station. Subtracting this time from 7:32 PM, the earthquake likely occurred between 7:21 PM and 7:24 PM at the station.
Do snail or earthworms travel faster?
earthworms travel faster
The Hubble Space Telescope is located in LEO. Does the telescope move faster or slower around the Earth compared with a geostationary weather satellite?
That is the exact questin i had!!
What are some of the Hubble telescope discoveries?
Some notable Hubble telescope discoveries include determining the age of the universe, observing distant galaxies and black holes, confirming the existence and nature of dark matter and dark energy, and providing important data on exoplanets and planetary systems.
According to Hubble's law the farther away a galaxy is?
According to Hubble's Law, the farther away a galaxy is the, faster it is moving away
What has the hubble telescope discoverd?
The Hubble telescope has expanded man's understanding of the universe in many ways. Here are a few: * helped astronomers determine the age of the universe much more accurately, * played a key role in discovering that a mysterious form of energy called dark energy is making the universe expand at a faster and faster rate, * detected the elements sodium, hydrogen, carbon, and oxygen in the atmosphere of a a large planet outside our solar system, * confirmed most galaxies have a black hole at their center, * proved that quasars, tremendous generators of light and other radiation which lie at the outer reaches of the universe, are located at the center of galaxies,
What is the general relationships between a galaxy's distance from earth and its speed?
were part of a galaxy?!! _____________________________ Yes, we are. It's part of the Earthling's Handbook; didn't you get a copy? The majority of other galaxies are moving away from us. (One notable exception is the Andromeda Galaxy; our Milky Way will probably collide with Andromeda in about 4 billion years or so.) Curiously, the farther away from us a galaxy is, the faster it seems to be receding! The relationship is called "Hubble's Law" for the man who figured it out, Edwin Hubble. (The Hubble Space Telescope is named in his honor.)
How far can the Hubble Telescope see into space?
Ah, the Hubble Telescope is an incredible wonder! It can see into space up to billions of light years away, uncovering the beauty and mysteries of our vast universe. Just imagine the dreams and wonders it captures out there, adding more colors to our celestial canvas.
How did Hubble tell the universe was expandining?
By the redshift of the galaxies. In general, the farther away a galaxy is from us, the faster it moves away from us.
Which is faster geostational satelite or the international space station?
1st
What causes congestion at a station?
multiple devices sending data to a single station at once a device sending data faster than the receiving station can receive station ca receive it
What is hubble's law?
Hubble's law is a law relating to objects in deep space that is named after Edwin Hubble, who helped verify its existence. Hubble's law states that objects in deep space are observed from Earth to have a radial velocity, measured by the Doppler shift in their spectra, which is proportional to their distance from us. In simpler, less quantitative words: Everything in the universe is moving away from us, and the farther it already is from us, the faster it's moving away from us.
Who was the astronomer that discovered the universe was expanding?
Edwin HubbleAnswer2:Hubble did not believe the universe is expanding. The universe is not expanding like the big bang, it is excited like an atom. The electrons jump to a higher level and lower their speed. The lower speed is a lower energy state, the max energy is when v=c.Hubble;s relationship v=HD indicates the distance D from the max energy state, where v = c.Hubble's Constant is dR/Rdt =c/R =H = 300M/150TT = 2E-18 m/s x31E21 = 62km/s/Megaparsec.
What is Edwin hubble know for?
Edwin Hubble is best known for his groundbreaking work in observational astronomy, particularly for establishing that the universe is expanding. His observations of distant galaxies led to the formulation of Hubble's Law, which states that the farther away a galaxy is, the faster it is moving away from us. This discovery fundamentally changed our understanding of the cosmos and supported the Big Bang theory. Additionally, Hubble played a key role in classifying galaxies and contributed to the development of the field of extragalactic astronomy.
