tronaut on a rocket ship is headed straight for another server is standing on Earth. If they both shine a flashl taneously as the rocket shin is moving away at a large

According to the formula for y, what would happen if the motion between the two frames was greater than the speed of light? Oy would be negative. Oy would be imaginary. O y would be one. O Nothing. O y would be infinity. Oy would be zero.

A spaceship departs from a space station and achieves a constant speed of 0.80cwith respect to thes tation, moving directly away from it. The spaceship fires a torpedo forward (in the same direction). The torpedo’s speed with respect to the spaceship is 0.40c. How fast is the torpedo moving with respect to the station?

Question 8 The star Betelgeuse is about 520 light-years away, If the speed of light were twice its present value, how far away would Betelgeuse be? O 2080 ly O 560 ly O 260 ly O 1040 ly O 130 ly Question 9 Which of the following is the reason for an ocean of water under Europa's frozen surface? O Europa had many icy comets crash into the surface bring water to the moon and melting the water as it fell into the core. O Furopa formed with an unusual amount of liquid water in the core and the coldness of space wasn't able to freeze it. O upiter's strong gravitational force is causing Europa to flex in its orbit, leading to an increase in internal heating. O Europa's close proximity to Jupiter puts it into a gravitational tug-of-war with Jupiter's targest moon Ganymede. Question 10 How was Neptune discovered? O When a large comet broke up and hit the planet, the explosion was seen from Earth-based telescopes O From a large sky survey that identified the "blue-green" planet. O By watching…

A Klingon spaceship moves to the right with a speed of 0.95c relative toEarth. The Enterprise spaceship moves to the left with a speed of 0.5crelative to the Klingon spaceship. Find the speed of the Enterprise as seenon Earth.

A healthy astronaut’s heart rate is 60 beats /min  Flightdoctors on Earth can monitor an astronaut’s vital signsremotely while in flight. How fast would an astronaut beflying away from Earth if the doctor measured her havinga heart rate of 25 beats/min ?

. A spaceship is traveling at 2,000 m/s when it begins to fire it rockets. This will cause the spaceship toaccelerate at 2 m/s2moving then?. Assuming the firing of the rockets last 15 seconds, how fast will the space ship be

(a) Calculate Ƴ for a proton that has a momentum of 1.00 kg.m/s. (b) What is its speed? Such protons form a rare component of cosmic radiation with uncertain origins.
