Physical Science Chapter 17 Notes The Moon Our calendar is tied to the phases of the moon. 29.5 days to circle the Earth. July 20‚ 1969 Apollo 11 landed on the moon. The astronauts placed a reflector to reflect the ray of an Earth-based laser beam. Determine the rate of continental drift Detect any change in the location of the North Pole Determine the orbit of the moon more accurate Moon is 2nd brightest object (Sun being the first) Standing on the moon‚ you would see a sunrise and sunrise

starts high above the earth’s atmosphere. The sun emits a continuous stream of ionized gas during its solar flares. This gas consists of electrons‚ protons and helium nuclei. The stream of gasses leaving the sun is known as the solar wind. As the solar wind approaches Earth‚ the particles are influenced by the Earth’s magnetic field and are guided toward oval zones around the magnetic poles. The solar wind particles then collide with air molecules in the upper atmosphere. The collisions impart energy

both part of the four terrestrial planets that orbit within the inner solar system and are from the same origin. They are both made of rock and metal. Mars has an extremely weak magnetosphere however‚ so probably doesn’t have a liquid metal core. Earth on the other hand does have a liquid metal core‚ which provides its strong magnetosphere. Solar radiation can therefore directly penetrate Mars‚ while Earth can reflect solar radiation. Mars is much further from the sun than Earth making it much

3.3. Moons of Uranus 3.3.1 Introduction Uranus‚ the seventh planet of the Solar System‚ has 27 known moons. Uranus’s moons are divided into three groups: thirteen inner moons‚ five major moons‚ and nine irregular moons. The inner moons are small dark bodies that share common properties and origins with the Uranus’s rings‚ the five major moons (Miranda‚ Ariel‚ Umbriel‚ Titania‚ and Oberon) are massive enough to have achieved hydrostatic equilibrium. They range in diameter from 472 km for Miranda

Using sources 1.1‚ 1.2 and 1.3 and your own knowledge‚ explain the changes in the solar cult before the reign of Amenhotep IV/Akhenaten (10 marks – 800 words) In a land like Egypt where the sun was one of the two dominating forces of nature (the other being the Nile)‚ it was natural for the people to worship the sun as a god. Solar (sun) worship had been practiced throughout Egypt in one form or another since Predynastic times. Popular beliefs about the sun god varied from place to place as did

Identification Ed Welsh and Bo Haeberle discovered an idea of the solar feeder. After years of developing‚ the product became very successful. It even won several prizes like the best new product in the Bird Watch America trade show‚ the national birding convention. After this‚ Ed and Bo decided to sell their final product under new established company Squirrel Defense‚ Inc. They opened a small shop in Greensboro and begin the production of the solar feeder so they could take orders for the demanded product

Introduction The energy consumed in Spain every day‚ both for the industrial sector‚ as for domestic consumers comes from multiple forms of primary energy sources‚ from which we get electricity. It is important to consider where these primary energy sources come from‚ and the value year after year the degree of self-sufficiency that primary energy resources have in Spain. The energy sector accounts for about 2.5% of the country’s Gross Domestic Product. However‚ this sector has a greater importance

The Effect of Dirtiness on Solar Panel Output__ Purpose: The purpose was to find out how much four years’ worth of grime will affect solar panel output Procedure: 1. Begin recording output from inverter for dirty solar panels 6 minutes and 35 seconds before apex of sun; record output every 5 seconds until 20 measurements have been recorded. Determine 5-second intervals by looking at stopwatch. 2. Use cleaning cloth and bucket of warm water to clean solar panels completely‚ taking 10
