Observer A on Earth sees spaceship B moving at speed v = 0.600c0 away from Earth and spaceship C moving at the same speed in the opposite direction. Observer A determines that both ships simultaneously sent out a radio signal at 12:00:00 noon and another signal at 12:05:00 p.m., making the time interval A measures between the emission of the signals from each ship ?tA = 5.00 min . Let ?tBB denote the time interval measured on ship B between the emission of signals on ship B , tBC denote the time interval measured on ship B between the emission of signals on ship C , and ?tCB denote the time interval measured on ship C between emission of signals on ship B . A). Is tBB greater than, less than, or equal to tA ? B). Is tBC greater than, less than, or equal to tCB ?
please like the answer. A humble request to you. Thank you.

My Note A spaceship is moving at a speed ot 0.9c away from an observer at rest. A boy in the spaceship shoots a proton gun with protons having a speed of 0.2c. (a) What is the speed of the protons measured by the observer at rest when the gun is shot away from the observer? (b) What is the speed of the protons measured by the observer at rest when the gun is shot toward the observer? O Type...
The spaceship Enterprise 1 is moving directly away from earth at a velocity that an earth-based observer measures to be +0.69c. A sister ship, Enterprise 2, is ahead of Enterprise 1 and is also moving directly away from earth along the same line. The veolcity of Enterprise 2 relative to Enterprise 1 is +0.45c. What is the velocity of Enterprise 2, (in terms of c) as measured by the earth-based observer?
Spaceships A, B, and C have the same proper length I, and according to an observer on Earth, are moving with same relativistic speed v in the +z, -, and -v direction, respectively. Find the length of each spaceship as measured by an observer in the Spaceship A. Spaceships A, B, and C have the same proper length I, and according to an observer on Earth, are moving with same relativistic speed v in the +z, -, and -v direction,...
A spaceship is moving away from Earth at speed 0.20c. A source on the rear of the ship emits light at wavelength 450 nm according to someone on the ship. What is the wavelength of the light observed by someone on the Earth?
An astronaut travels away from the Earth at a speed of 0.74c and sends a light signal back to the Earth every 9.0 s as measured by his clock. An observer on the Earth finds that the arrival time between consecutive signals is Δt. Find Δt. (Answer should be in seconds)
Please show every step Two spaceships approach Earth with equal speeds, as measured by an observer on Earth, but from opposite directions. A meterstick on one space- ship is measured to be 60 cm long by an occupant of the other spaceship. What is the speed of each spaceship, as measured by the observer on Earth? (A) 0.4c (B) 0.5c (C) 0.6c (D) 0.7c (E) 0.8c
A spaceship travels with a speed of 0.3 c as it passes by the Earth on its way to a distant star, as shown in the diagram below. The pilot of the spaceship measures the length of the moving ship as 40 m. 0.3 c Earth Determine its length as measured by a person on Earth. (part 2 of 3) The pilot of the spaceship observes that the spaceship travels for 4 years. Determine how much time has passed according...
a spaceship of proper length 50 m is moving away from the earth at a speed of .8c . according to the observes in the ship , their journey takes 6.0 hours . according to observers on earth , what is the length of the ship and how long does the journey take ?
Spaceship A moves away from Earth at a speed vA = 0.776c (see figure). Spaceship B pursues at a speed vB = 0.891c relative to Earth. Observers on Earth see B overtaking A at a relative speed of 0.115c. With what speed is B overtaking A as seen by the crew of spaceship B?
Spaceship A moves away from Earth at a speed vA = 0.728c (see figure). Spaceship B pursues at a speed vB = 0.981c relative to Earth. Observers on Earth see B overtaking A at a relative speed of 0.253c. With what speed is B overtaking A as seen by the crew of spaceship B?
