A communications satellite orbiting the earth has solar panels that completely absorb all sunlight incident upon them. The total area A of the panels is 10m2. 1) The intensity of the sun's radiation incident upon the earth is about I=1.4kW/m2. Suppose this is the value for the intensity of sunlight incident upon the satellite's solar panels. What is the total solar power P absorbed by the panels? Express your answer numerically in kilowatts to two significant figures. 2) What is...
In Example 34.6, we imagined equipping 1950DA, an asteroid on a collision course with the Earth, with a solar sail in hopes of ejecting it from the solar system. We found that the enormous size required for the solar sail makes the plan impossible at this time. Of course, there is no need to eject such an object from the solar system; we only need to change the orbit. A much more pressing problem is Apophis, a 300-m asteroid that may be...
Constants In this example we will investigate the viability of using radiation pressure to propel a spacecraft. Suppose a spacecraft with a mass of 2.50 x 10 kg has a solar sail made of perfectly reflective aluminized film with an area of 2.59 x 106 m2 (about 1 square mile). If the spacecraft is launched into earth orbit and then deploys its sail at right angles to the sunlight, what is the acceleration due to sunlight? (At the earth's distance...
Problem Solving: LightSail 2 LightSail 2 was a satellite that was designed to use solar radiation to change its altitude as it circled Earth. The spacecraft had a mass of 5.0kg. It was originally launched by a rocket with its sail closed, and established an orbit at an altitude of 720 km above Earth’s surface. Then it deployed its sail, which had an area of 32m2. Assume the sail is completely reflective. 1) After a full month of “½...
Please use the formulate sheet and show all steps to make sure the question is worth any points a) The initial ratio of deuterium (D) to hydrogen (H) in a planet's atmosphere was 175000; however, the present ratio is 1/1500 and the initial and final abundances of D are 5 x 10° atoms per m3 and 9 x 106 atoms per m2, respectively. What fraction of deuterium has been lost, and what fraction of hydrogen has been lost in this...
summatize the following info and break them into differeng key points. write them in yojr own words apartus 6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
