While passing between Earth and the Moon, a spacecraft is momentarily located on the line connecting the centers of the two bodies and is at a distance of d = 101 km from a radio antenna on the surface of Earth. The distance from the antenna to the moon is denoted by dm.
Part (a) Recall that the speed of light is 3.0 × 108 m/s. How long, in seconds, does it take for a signal from the spacecraft to arrive at the antenna on Earth?
Part (b) Scientists on Earth send a command to the spacecraft, which immediately sends back a receipt confirmation signal. How long, in seconds, after the scientists send the command does it take before they learn it was received?
Part (c) Scientists bounce a laser beam off the Moon and measure the two-way travel time to be 2.42 s. How far away is the Moon in meters?

You have to cross the interstellar medium with anthe approximated density of 1 hydrogen atom/m3Because you are moving at an enormous speed, your mission from the previous part will be influenced by the effects of time dilation described by special relativity: Your spaceshiplaunches in June 2020 and returns back to Earth directly after arriving at Sirius.(a) How many years will have passed from your perspective?(b) At which Earth date (year and month) will you arrive back to Earth?arrow_forwardThe Global Positioning System (GPS) relies on very accurate atomic clocks aboard a network of 24 satellites, each of which orbits the Earth in 12 hours. To provide a resolution better than 1 meter on Earth, the clocks must not gain or lose more than 3 ns in 12 hours. That is, the clocks must be accurate to 3 x 10-⁹ s/(12 hr) = 7 × 10-14 The satellites move at a speed v = 3.9 km/s in circular orbits.

- High-Energy Cancer Treatment. Scientists are working on a new technique to kill cancer cells by zapping them with ultrahighenergy (in the range of 1012 W) pulses of light that last for an extremely short time (a few nanoseconds). These short pulses scramble the interior of a cell without causing it to explode, as long pulses would do. We can model a typical such cell as a disk 5.0 um in diameter, with the pulse lasting for 4.0 ns with an average power of 2.0 * 1012 W. We shall assume that the energy is spread uniformly over the faces of 100 cells for each pulse. (a) How much energy is given to the cell during this pulse?
