- In determining the distance to a cloud, a meteorologist in a TV station uses radar and notes that a time of 0.2 ms elapses between the sending and return of a radar pulse. How far away is the cloud?A person on earth communicating via radio transmission with an astronaut on the moon asks a question. At the time of transmission the moon is 4.00 x 10^5 km from the earth, and the speed of radio waves is 3.00 x 10^8 m/s. How long must the person on earth wait for a response if the astronaut answers 2.50 seconds after the message is received?A person on earth communicating via radio transmission with an astronaut on the moon asks a question. At the time of transmission, the moon is 3.843.84 × 10105 km from the earth, and the speed of radio waves is 3.003.00 × 10108 m/s. How long must the person on earth wait for a response if the astronaut answers 5.005.00 s after the message is received?
- 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 µm in diameter, with the pulse lasting for 4.0 ns with an average power of 2.0 x 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? (b) What is the intensity (in W/m2 ) delivered to the cell? (c) What are the maximum values of the electric and magnetic fields in the pulse?A distant galaxy emits light that has a wavelength of 655.6 nm. On earth, the wavelength of this light is measured to be 661.9 nm. (a) Decide whether this galaxy is approaching or receding from the earth. (b) Find the speed of the galaxy relative to the earth. (Give your answer to 4 significant digits. Use 2.998 × 108 m/s as the speed of light.)Conversations with astronauts on lunar walks had an echo that was used to estimate the distance to the Moon. The sound spoken by the person on Earth was transformed into a radio signal sent to the Moon, and transformed back into sound on a speaker inside the astronaut’s space suit. This sound was picked up by the microphone in the space suit (intended for the astronaut’s voice) and sent back to Earth as a radio echo of sorts. If the round-trip time was 2.60 s, what was the approximate distance to the Moon, neglecting any delays in the electronics?
