- i have no clue where to start with this question.A Cepheid variable star is a star whose brightness alternately increases and decreases. For a certain star, the interval between times of maximum brightness is 4.3 days. The average brightness of this star is 4.0 and its brightness changes by ±0.45. In view of these data, the brightness of the star at time t, where t is measured in days, has been modeled by the function B(t) = 4.0 +0.45 sin (a) Find the rate of change of the brightness after t days. dB dt (b) Find, correct to two decimal places, the rate of increase after five days. dB dtA particle has a mass of 1.6E-27kg and a momentum of 2.2E-18 kg.m/s. What is the speed of the particle? Express your answer in units of c, the speed of light. Keep four significant digits.
- A particle has a mass of 1.88E-28 kg and it travels at a speed of 0.969c, where c is the speed of light. What is the energy of the particle, expressed in MeV. Keep three significant digits.You're caught running a red light on Hwy 316. Attempting to impress the skeptical patrol officer with your physics knowledge, you claim that you were traveling so fast that the red light (693 nm) appeared yellow (582 nm) to you. How fast would you have been traveling (in mi/hr) if that had been the case?The 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 = J
- Bryce, a mouse lover, keeps his four pet mice in a roomy cage, where they spend much of their spare time (when they are not sleeping or eating) joyfully scampering about on the cage's floor. Bryce tracks his mice's health diligently and just now recorded their masses as 10.3 g,18.5 g,11.3 g, and 18.3 g. At this very instant, the x‑ and y‑components of the mice's velocities are, respectively, (0.115 m/s, −0.527 m/s), ,(−0.237 m/s, −0.391 m/s), ,(0.843 m/s, 0.455 m/s), and (−0.897 m/s, 0.135 m/s). Calculate the x‑ and y‑components of Bryce's mice's total momentum, px and Py. px____kg.m/s py ____kg.m/sA particle has γ=18,399. a) Calculate c-v in m/s.

- Earth's neighboring galaxy, the Andromeda Galaxy, is a distance of 2.54 x 10' 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 vmin 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 umin and the speed of light c. C- Umin = m/sFind the kinetic energy of the objects in the scenarios. A. A cosmic pion of mass 140 MeV/?2140 MeV/c2 flies through outer space at a speed of 9.61×103 km/s9.61×103 km/s. See the hint for help converting MeV/?2MeV/c2 to kg.The dimensionless parameter γ is used frequently in relativity. As γ becomes larger and larger than 1, it means relativistic effects are becoming more and more important. A. What is γ if v = 0.28c? B. What is γ if v = 0.53c?
