Is speed relative to mass?
Speed is not directly relative to mass. An object's speed is determined by its velocity, which is a measure of both the speed and direction of its motion. While mass can affect an object's acceleration and how it responds to external forces, it does not directly determine its speed.
How long would it take to travel to another galaxy at the speed of light?
Traveling to another galaxy at the speed of light would take an incredibly long time. The closest galaxy to us, the Andromeda galaxy, is about 2.5 million light-years away. This means it would take 2.5 million years to reach Andromeda at the speed of light.
If you walk towards a mirror at a certain speed the relative speed between you and your image is?
You can be twice as certain about your speed now.
Which of these is true of a person walking up the steps of a downward-moving escalator a a constant speed?
Here are some things that are true:* The combined speed is also constant * To get the combined speed, you need to subtract one speed from the other (the speed of the escalator, and the speed of the person relative to the escalator) * Acceleration is zero
What does relative refractive index tells?
The relative refractive index describes the change in speed of light as it moves from one medium to another, indicating how much the light bends or refracts at the interface of the two media. It is calculated as the ratio of the speed of light in a vacuum to the speed of light in the medium in question. The larger the relative refractive index, the more the light is bent or refracted as it enters the medium.
Does the speed of light allow the Andromeda Galaxy to emit a blue shift?
There is some blueshift in the Andromeda galaxy as it is moving toward us. The speed of the Andromeda Galaxy relative to the sun is about 300 kilometers per second or about 0.1% the speed of light. The blueshift would be detectable by instruments but not to the human eye.
What is the speed of the Andromeda galaxy in 100km per sec?
The Andromeda galaxy is moving towards our Milky Way galaxy at a speed of about 110 km/s. This relative motion is causing the galaxies to slowly approach each other and will eventually result in a collision in billions of years.
What is the orbital speed of the sun?
The sun orbits around the center of the Milky Way galaxy at an average speed of about 450,000 miles per hour (720,000 kilometers per hour). This orbital speed is influenced by the gravitational pull of the galaxy's massive black hole at the center, as well as the gravitational interactions with other celestial bodies in the galaxy.
What is earths pace in the universe?
I assume that with "pace" you mean "speed". The speed depends what you measure it against; for example, Earth moves at a speed of 30 km/second around the Sun, but the numbers vary if you determine the speed around the center of the Milky Way, around the center of mass of the Local Group, or compared to the background radiation.
How far does the sun travel in day point a to point b?
Nobody knows. Motion is relative to some fixed unmoving point (at least for the purposes of that problem). A car has a speed of 50 miles per hour. This is relative to the surface of the earth. We pretend the earth is not moving but we know it is moving around the sun. When discussing the speed of the earth we pretend the sun is not moving, but it is moving around the center of our galaxy. Our galaxy is not even stationary. E. Hubble discovered that the universe is expanding and galaxies are moving away from each other. There is no absolute motion, so there is no absolute speed, nor even absolute time according to the theory of relativity. According to WIKIPEDIA the sun moves at a rate of about 220 km/s relative to the center of the Milky Way galaxy. The sun moves at 20 km/s relative to other stars in our region. But in relation to the Cosmic Background Radiation, the sun moves at about 370 km/s. So pick one. In 1 day there is 60x60x24 = 86400 seconds. Relative to the center of the Milky Way, the sun moves 220 x 86400 = 19,008,000 kilometers in one day.
What is the rotation speed of Andromeda galaxy?
The Andromeda galaxy rotates at a speed of about 100 to 200 kilometers per second at its outer edges, and faster towards its center. It takes approximately 200 million years for Andromeda to complete one full rotation.
How long does it take for the milkyway galaxy to rotate 1 time?
The Milky Way galaxy takes about 200-250 million years to complete one full rotation. This rotation speed varies based on the distance from the center of the galaxy, with stars closer to the center orbiting faster than those further out.
How long would it take to get to center of your galaxy at the speed of light?
Objectively, about 26,000 years - but IF (and you cannot!) you could travel at the speed of light, it would seem like no time at all had passed.
What is orbit of the sun?
The sun is in an enormous orbit around the center of the Milky Way galaxy. It is estimated that it takes between 225 and 250 million years for the sun to make one orbit, called a galactic year. We are traveling around the center of the galaxy at a rate of about 220 km/second, which is .073% of the speed of light.
How many revolutions around the galaxy has earth made in 4.6 billion years of existence?
The Earth Orbits the sun, and the sun revolves around the center of of the galaxy at 250 km/s. At this speed it completes one revolution about every 200 million years. Therfore the earht has made about 23 revolutions around the center of the galaxy.
What speed does have the earth?
Speed must be specified relative to something. Relative to the Sun, the speed of Earth is about 30 km/second. Relative to the Milky Way, or relative to the Local Group, you would get different numbers.
At what speed does everything rotate within the Milky Way galaxy, including the Milky Way galaxy itself?
Well, isn't that just the most lovely question! You see, everything in our Milky Way galaxy spins peacefully like a gentle dance in the meadow. The Milky Way itself also gracefully twirls through space at a speed of about 220 kilometers per second. Just take a moment to appreciate the beauty of it all. Everything is right where it should be.
