Chapter 24 Electromagnetic Waves 6. A neodymium-glass laser emits short pulses of high-intensity of electromagnetic waves. The electric field of such a laser pulse has an rms value of Ems = 8.0 x 10' N/C. (a) Determine the average power of each pulse that passes through the cross-sectional area of of the laser beam A -5.05 x 10-5 m. (b) Determine the average intensity of this laser in W/m². - 4-
QUESTION 17 The International Space Station which presently has mass of about 420,000 kilograms, maintains an orbit with an altitude of between 330 and 435 kilometers (205 and 270 miles respectively) above the Earth surface by means of re-boost maneuvers using the engines of the Zvezda module or visiting spacecraft to compensate for 2 km/month orbital decay due to the atmospheric drag. Calculate the following for the low orbit of the ISS (330 kilometers above the Earth surface), assuming that...
