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 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 earth, and the speed of radio waves if 3.00 x 10^8 m/s. How long must the person on earth wait for a response if the astronaut answers 2.50 s after the message is received?
A spaceship is approaching a space station at a speed of 2.25 ✕ 105 m/s. The space station has a beacon that emits green light with a frequency of 5.99 ✕ 1014 Hz.

c = 2.9979 ✕ 108 m/s
for the speed of light. Enter your answer to at least five significant figures.) Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. Hz(b) What is the change in frequency? Hz
