- Two astronomical events are observed to occur at a time of 0.30 s apart and a distance separation of 2.0109m from each other. How fast must a spacecraft travel from the site of one event toward the other to make the events occur at the same time when measured in the frame of reference of the spacecraft?arrow_forwardThe nearest neutron star (a collated star made primarily of neutrons) is about 3.00 1018 m away from Earth. Given that the Milky Way galaxy (Fig. P1.81) is roughly a disk of diameter 1021 m and thickness 1019 m, estimate the number of neutron stars in the Milky Way to the nearest order of magnitude. Figure P1.81arrow_forwardA spacecraft is launched from the surface of the Earth with a velocity of 0.600c at an angle of 50.0° above the horizontal, positive x-axis. Another spacecraft is moving past with a velocity of 0.700c in the negative x direction. Determine the magnitude and direction of the velocity of the first spacecraft as measured by the pilot of the second spacecraft.arrow_forward
- Show that the velocity of a star orbiting its galaxy in a circular oibit is inversely proportional to the square root of its orbital radius, assuming the mass of the stars inside its orbit acts like a single mass at the center of the galaxy. You may use an equation from a previous chapter to support your conclusion, but you must justify its use and define all terms used.arrow_forwardWhat is the speed of light (c=3.0∗10^8m/s) in kilometers per hour?arrow_forwardThe speed of light is exactly e = 299792458 m - s1. (Also written 299, 792, 458 m - s-1 or 2.99792458 × 10°m - s1. This is exact because it is the definition of the metre.) It takes light 8.3 minutes to get from the sun to the earth. Assuming that the earth's orbit is exactly circular (an approximation) and that its speed is constant, and using the data in this question, calculate the speed of the earth in its orbit around the sun in km · hr. Practise writing your conversions clearly using the 'multiply by 1' technique. Speed of the earth =_ km per hour. Write your answer in standard (not scientific) notation, i.e. without using exponents, and without using commas. However, remember to use the correct number of significant figures. (Hint: which is the least precise of the given data?) Do not include units.arrow_forward
- A spacecraft is moving relative to the earth.An observer on the earth finds that, according to her clock, 3601 s elapse between 1pm and 2pm on the spacecraft’s clock.What is the spacecraft’s speed relative to the earth?arrow_forwardYou are an engineer assigned to build a spaceship. The length and diameter of your spaceship as measured by an astronaut on board are 80.0 m and 25.0 m, respectively. The spaceship moves at 70% the speed of light relative to you on Earth in a direction parallel to its length. What are its dimensions as measured by you on Earth?arrow_forwardThe speed of a gravitational wave is reported to be the same as the speed of light, which is 3.0 x 108 m/sec. How many times in 1.0 sec would a traveler moving at the speed of light circumnavigate the Earth at the poles where the diameter is roughly 7.8998 x10³ miles?

What is the diameter of the moon observed by Porkins in the direction parallel to the direction he is moving? Answer in km.arrow_forwardWhat do you think would be different in everyday life if the speed of light were 10 m/s instead of 3.00 * 10^8 m/s ?arrow_forwardAn alien spaceship travels at v=0.999c-299482km/s (where 'c' is the speed of light equal to 299782 km/s) past the International Space Station (ISS) which orbits the Earth. According to NASA, the ISS is approximately 109m long when they finished building it. What length would the alien spaceship measure? Just under 5m. Just over 200m. The same length, 109m. Just under 100m.arrow_forward
