- Can you answer problem 3?arrow_forwardWhat do you understand by time dilation? What is proper time and establish a relation for proper time. A beam of particle of half-life 2×10-8 sec travels in laboratory with speed 0.96 times the speed of light. How much distance does the beam travel before the flux falls to ½ time the initial flux.arrow_forwardSuppose a spaceship of length L, is traveling at a high rate of speed v relative to an observer. To the observer, the ship appears to have a smaller length given by the following formula. L=L/1- where c is the speed of light Complete the parts (a) through (d). (a) What is the observed length L of the ship if it is traveling at 50% of the speed of light? Choose the correct answer below. O B. L=0 V5 OA L= OD.

- Please answer following questions: a. How does special relativity affect the following general principles of physics you have learned so far? Explain your response: principle of relativity (laws of physics not dependent on inertial reference frame), conservation of energy and momentum, calculation of relative velocity, and principle of inertia (i.e. Newton's First Law). b. How does special relativity affect the application of general principles of physics? In particular, answer for: conservation of energy and momentum, and calculation of acceleration of a body under a force.arrow_forwardWhere is an image located if it is viewed with a relaxed eye? For a simple magnifier where is the object located to produce an image that is viewed with a relaxed eye? What are the postulates of special relativity? Name two consequences of the postulates of special relativity. Why is the mass of a nucleus less than the mass of the particles that make it up? Comment on whether mass is or is not a conserved quantity. In a nuclear reaction name two quantities that are conserved?arrow_forwardActivity 3: What is your time? "The faster you move in space the slower you move in time" Suppose a space traveller in a space ship passed by you in a whooping speed, almost the speed of light. The space traveller, in his clock, measured a time elapse of one second. fast! Will you measure the same elapsed time? Why? Why not? You might think that the time measured by the spaceman and your measured time should not matter. However, the time for each frame of reference really matters. One of the consequences of Einstein's postulates of Special Theory of relativity is stretching of time. If we agreed that the laws of Physics are the same for all observers for inertial reference frames and that the speed of light is constant, then it would only be possible if time is not absolute. It means that observers at different frames will observe and experience time in different ways. Time then is something personal for every observer. Very odd indeed! We call this as time dilation. How much time…arrow_forward
- You are traveling in a spaceship, headed towards Earth, and you hold a ball at arm's. When you let go of the ball, it falls to the floor as shown in the picture. What does this observation tell you about the acceleration of the spaceship? If you shine a white light out of the window of the spaceship towards Earth, at what speed will the light appear to travel and why? What colour will the light appear to be to observers on Earth, and why?arrow_forwardExplain the implications and applications of each postulate of Einstein from the special theory of relativity.arrow_forwardArmed with highly sensitive detection equipment, you are in the front of a railroad car that is accelerating forward. Your friend at the rear of the car shines green light toward you. Do you find the light to be red-shifted (lowered in frequency), blue-shifted (increased in frequency), or neither? Explain. (Hint: Think in terms of the principle of equivalence. What is your accelerating railroad car equivalent to?)arrow_forward
