Please provide step by step solutions so I can understand them better. Thank you.

Calculate the relativity factor for two observers whose relative velocity ts 0.43c. 9. An observer stands next to a lightning rod in an inertial reference frame at rest with respect to a barn's weather vane 9.50 x 108 meters away. The observer secs lightning strike the vane 2.00 seconds before it strikes the lightning rod. Find the proper time heme-en the events. rm an 't'EZQFzWJEe Fame-"43.7: .. -- h\" 9.50 x105 m"'i 10. An observer in another reference frame measures the time interval between two events that occur at the same place. measures the rest mass of an object, and measures the distance between two xed points in his reference frame. We will make the same measurements in our reference frame that is moving with a constant velocit} with respect to the observer's reference frame. An observer in a spaceship moving at 0.65r with respect to the earth made proper measurements of time. mass' and length parallel to the relative velocity. He measured 3 hours. 32 kilograms. and 0.18 m. What measurements would we get for (a) Time (b) Mass (C) Length parallel to the relative velocity
