The Juno spacecraft arrived at Jupiter on July 4, 2016. Assuming the distance between the Earth and Jupiter is approximately 6.30 × 1011 m, determine the time, in minutes, for a signal traveling at the speed of light to reach Earth from Juno.

00 How long does it take (in seconds) for light to travel from the Sun to Saturn if the Sun is roughly 1.5 10^9 km away and the speed of light is 3*10^8 m/s? (Only write the number; your answer is assumed to be calculated in seconds) hp & #3 2$ backs 4 5 7 9. e r y d f h j k

A microscopic spherical dust particle of radius r and mass m is moving in outer space at a constant speed v. A wave of light strikes it from the opposite direction of its motion and gets absorbed. Assuming the particle decelerates uniformly to zero speed in time t, write an equation for the average electric field amplitude in the light.

How long should it take the voices of astronauts on the Moon to reach the Earth? Assume that the only significant time is the transit time from the Earth to the Moon, at the speed of light. Suppose that the astronaut on the surface of the Moon, the receiver on the surface of the Earth, and the centers of the Earth and the Moon are aligned. The distance between the centers of the Earth and the Moon is 384×103km, the radius of the Earth is 6.38×103km, the radius of the Moon is 1.74×103km.

(a) Approximately how long would it take a telephone signal to travel 2810 mi from coast to coast across the United States? (Telephone signals travel at about the speed of light.) b) Approximately how long would it take a radio signal to reach the International Space Station (ISS) at an orbital altitude of 350 km?

(a) In communicating with an astronaut on the moon, 3.8  108 m from earth, what is the minimum time delay in getting a response to a question? (b) What would the minimum time delay be for communication with an astronaut at a distance of 4 light-years from earth?

Processes at the center of a nearby galaxy cause the emission of electromagnetic radiation at a frequency of 3.97×1013 Hz.Detectors on Earth measure the frequency of this radiation as 3.11×1013 Hz. How fast is the galaxy receding from Earth?
