Question

Because the orbital speed of the planet changes along an elliptical path, solar noon may arrive a few minutes earlier or later than might otherwise be expected. On October 30, at what time of the day will the sun reach its highest position in the sky? On a small sailboat in the open ocean far from land, does the navigator use a sextant and a chronometer to determine his/her location on the planet? Do not explain how a sextant works: only what it does. Which is the only type of energy transfer that can traverse through empty space? Write your answer on the line provided. All matter which is above absolute zero in temperature emits electromagnetic radiation. Write the letter of the correct answer on the line provided. True False By what process is sunlight produced in the sun? Write your answer on the line provided. this is a two part question: What is solar wind? In what ways is solar wind sometimes harmful?

Explanation / Answer

27.He can calculate his longitude by comparision with local time founded by his sextant observation of sun.

28.Energy transfer is only by radiation.

29.True.

30.Sun is a large ball of hydrogen and helium undergoing through nuclear fusion.The dominent nuclear fusion process occuring in the sun that produces a vast majority of light.

31.A solar wind is a strem of charged particles flowing outward from the sun.It constantly carries magnetic field from the sun.In solar wind ,the particles tend to follow magnetic field lines with additional scattering from irrregularities in the magnetic field.The particles making the solar wind are harmful.

Upon reaching the earths magnetic field,most solar winds are deflected and some creep into the atmosphere at two poles.Areas close to north pole and south pole experience auroras.they are capable of creating geomagnetic stroms.
