A distant galaxy is moving away from Earth at a speed of 70,000 km/s. If a star in that galaxy emits light at a wavelength of 450 nm, what is the wavelength of that light when it reaches Earth? Speed of light c= 300,000 km/s.
Consider a spiral galaxy that is moving directly away from Earth with a speed V=3.24*10^5 at its center. The galaxy is also rotating about its center such that points in the spiral arms are moving with a soeed V=5.750*10^5m/s relative to the center. If light with a frequency of 7.308*10^14Hz is emitted in both arms of the galaxy, what frequency is detected by astronomers observing the arm that is moving (a) toward and (b) away from Earth? Please break down...
Most of the galaxies in the universe are observed to be moving away from Earth. Suppose a particular galaxy emits orange light with a frequency of 5.000×1014Hz. If the galaxy is receding from Earth with a speed of 4875 km/s, what is the frequency of the light when it reaches Earth?
Most of the galaxies in the universe are observed to be moving away from Earth. Suppose a particular galaxy emits orange light with a frequency of 5.000×1014Hz. If the galaxy is receding from Earth with a speed of 5000 km/s, what is the frequency of the light when it reaches Earth?
Earth's neighboring galaxy, the Andromeda Galaxy, is a distance of 2.54×107 light-years from Earth. If the lifetime of a human is taken to be 75.0 years, a spaceship would need to achieve some minimum speed ?min to deliver a living human being to this galaxy. How close to the speed of light would this minimum speed be? Express your answer as the difference between ?min and the speed of light ?. ?−?min= __________ m/s
A galaxy is moving away from us at 2.5 *10^7m/s. What is the frequency of light observed by us if the wavelength of the emitted light is 500 nm?
a spaceship of proper length 50 m is moving away from the earth at a speed of .8c . according to the observes in the ship , their journey takes 6.0 hours . according to observers on earth , what is the length of the ship and how long does the journey take ?
Light and the Electromagnetic Spectrum Examples 1) The distance from the Sun to Earth is 1.50 x 1011 m. How long does it take for light to cover this distance? 2) Suppose a particular galaxy emits orange light with a frequency of 5.000 x 1024 Hz. If the galaxy is moving away from Earth with a speed of 3325 km/s, what is the frequency of the light when it is observed on Earth?
According to Hubble's Law the velocity v of a galaxy moving away from Earth is proportional to its distance from Earth. Consider two galaxies one of which is twice as far away as the other from Earth at some instant of time (i.e. the ratio of their distances from Earth is 2 to 1). At subsequent times the ratio of their distances to Earth will be:
These are the answers, please provide the work for the
calculation
1. Two cells that subdivide on Earth every 10.0s start from the Earth on a journey to the Sun (1.5 x 1011 m away) in a spacecraft moving at 0.850c. How many cells wil exist when the spacecraft crashes into the Sun? Earth time is 588s. Spacecraft time is 310s or 31 cycles of division. 2312.1x 10 cells at the end of the journey. 2. As a spacecraft moving...
