Eart 30Washington, D.C., is located at about 750 W longitude and 380 N latitude. San Francisco is near 1270 W longitude and 380 N latitude. Estimate how many minutes later the Sun rises in San Francisco than inWashington, D. C. How far apart would you estimate these cities to be? Assume that the earth’s radius is 6400 km. One day has 1440 minutes and of course the earth rotates 360 degrees around its axis in one dayIn Lorentz transformation appears the Lorentz factor denoted by the Greek letter Y. This Lorentz factor Select one: a. depends on the relative speed between two inertial reference frames. b. depends on the location of the event as seen by two inertial reference frames. depends on the velocity of the particle on which we want to perform the transformation. c. d. depends on the speed of the particle on which we want to perform the transformation. e. is an invariant constant of nature. ⚫ f. depends on the relative velocity between two inertial reference frames. ×
- What is proper time? A. The time calculated for the person moving at relativistic speed. B. The longest possible time interval between two events. C. The time measured by the clock that travels with the observer. D. The time measured by a light clock.1) A 5-kg particle's momentum is (211, 329) kg*m/s. Calculate its kinetic energy. 2)Calculate the x-component of vSJ. vS = 6 km/s vJ = 9 km/s θ = 23o 3) In Jupiter's frame, the incoming spacecraft is moving rightward and upward, at 45o. The outgoing spacecraft, having already flown by, is going at the same relative speed, but leftward and upward, also at 45o. (See the figures.) You are going to transform back to the sun's frame and calculate the final outgoing speed. You need to follow several steps: Calculate the vector components of the outgoing vSJ. Add Jupiter's vector velocity to get the outgoing vS. Finally calculate the outgoing speed, vS = |vS| in km/s. Enter that as the final answer. use these parameters: vSJ = 4 km/s vJ = 8 km/show do I convert a Newton*meter/meter^2 to Newton/meter^2 I figured out that I divied by 1000 but I dont understand how the units cancle my actual numerical answer is 266240Nm/m^2 and the correct answer is 266.24 N/m^2
