NO SCIENTIFIC NOTATION ANSWERS THANK YOU
The special theory of relativity has what effect on measurements done today? (a) None whatsoever, because any correction would be negligible. (b) We need to consider the effects of relativity when objects move close to the speed of light. (c) We should always make a correction for relativity because Newton’s laws are basically wrong. (d) It doesn’t matter, because we can’t make measurements where relativity would matter.
A light-year is the distance that light can travel in one year. Similarly, we can define a light-second, light-day, etc. as the distance that light can travel in other time intervals. Calculate the distance represented by each of the following: (Assume that the speed of light is 3 × 108 m/s).
1. 4 light-seconds
2. 3 light-minutes
3. 2 light-days
4. 2 light-days, but this time answer in miles (enter just the number with no units)

Previously got so many wrong answers. A muon has an average life time t_0 = 2.2μs from Earth's frame of referance. Needed distance for them to be found on earth surface is 6Km . What is the average life time of muon from it's own frame of referance if they are travelling with an speed of 2.978×108 m/s ?arrow_forwardParticles accelerators such as the Large Hadron Collider (LHC) can accelerate particles up to tremendous energies. Suppose the LHC accelerates alpha particles (a.k.a. helium nuclei with a charge of +2e and a mass of 6.645 x 10-27 kg) with a kinetic energy of 7.5 TeV*, what would the speed of one particle be if relativistic effects** are ignored? Give your answer in units of Gm/s. *T as in Tera, for 1012. "eV" stands for "electron volt," which is a non-Sl unit of energy equal to what one electron would gain after travelling through 1V. 1eV = 1.602 x 10-19 J. **Special relativity is necessary to correctly account for the limiting speed of light, which is about 3 x 10° m/s. Note that in ignoring this effect and applying Newtonian mechanics (what you learned in Phys1210 or equivalent), you'll be getting a speed way above 0.3 Gm/s. That's just how insanely energetic the LHC is.arrow_forward
- In the context of relativity, what is an "event"? Give a specific example of an event and provide the coordinates necessary to specify the event.arrow_forwardThe principle of relativity was recognised as both a mechanical and optical effect. Einstein believed that the principle should hold for both situations. One of his thought experimentds involves him sitting on a train travelling at the speed of light and looking at a mirror. He asked the question as to whether he would be able to see his own reflection. a) Outline one possible answer to Einstein's question and the problems involved in your answer in terms of the principle of relativity. b) What was Einstein's conclusion to this thought experiment?c) The theory of relativity discusses the physical consequences of a universal frame of reference. The special theory of relativity, published in 1905 by Albert Einstein, is concerned with problems involving inertial frame of reference. Its fundamental principles, however, caused discrepancies in measurements. Describe TWO apparent discrepancies caused by these fundamental principles.arrow_forwardQuasars are faint, distant sources of radio waves. (Quasar is short for "quasi-stellar source." They are so named because, like a star, they appear to the astronomer to be pointlike.) From the shift in the frequency of their emitted light toward the red, called the "redshift," we know that quasars are moving very fast. Astronomers observe that the more distant an object is from the earth, the faster it moves. In this way they determine that quasars are billions of light years from earth. To be visible at this great distance, quasars must have enormous luminosity. Typically a quasar radiates energy at a rate on the order of 1040 W, roughly 1014 times greater than the sun or 40 times greater than the most luminous galaxy. At what rate is rest mass being consumed to produce this much radiation? Quasar 3C-273arrow_forward

What is the speed of the particle, expressed in units of c, c being the speed of light. Keep three significant digits. Note: In my class, we don't use E = mc^2. Our professor has us use E = gamma(mc^2)arrow_forwardThe following quotation is taken from the article “Quantum Black Holes”, by Bernard J. Carr and Steven B. Giddings, in the May 2005 issue of Scientific American. "The total time for a black hole to evaporate away is proportional to the cube of its initial mass. For a solar-mass hole, the lifetime is an unobservably long 1064 years." a. Recall that the solar mass is 2 × 10³0 kilograms. Write a formula for the lifetime, L, of a black hole as a function of its mass, m. Start by finding the value of the constant k, then write your function using the letter k (rather than its value in scientific notation). For example, for a direct variation you would write “L(m) = km”. k = a × 10¹ where a = L(m) = b. The present age mass = c × 10ª kg, where c = A and b = = of the universe is about 10¹0 years. What would be the mass of a black hole as old as the universe? ID and d = Jarrow_forward
