(a) the top to the tube Choosing how to structure our CSS components. ii) A head or round coma that surrounds the centre and consists of dust particles mixed with frozen water, frozen methane and frozen water, frozen methane and frozen ammonia. Kepler’s laws were derived for orbits around the sun, but they apply to satellite orbits as well. That’s much easier than saying that Mars is 227,939,000 km away from the Sun. Part-I (General Science) 60 Marks. (a) Carbon dioxide Given models, illustrations, and diagrams, students will describe components of the universe, including stars (including the description of the Sun and its properties), nebulae, and galaxies, and use models such as the Hertzsprung-Russell diagram for classification.

Constituents and Structure: “Universe, Galaxy. (a) black hole We define a few sizes that we are going to use, I quite like the way in which Bootstrap makes it. The Universe is vast. It is not at all easy for many reasons, and not only because of the difficulty of simplifying things for non-specialists without leaving any loose ends that we take for granted. The Law of Areas: A line that connects a planet to the sun sweeps out equal areas in equal times. Composition & Internal Structure of the Earth Any group of diverse materials can be classified by chemistry or physical properties. A) Big icy particles of hail of diameter 4.5 cm (a), 5 cm (b), and 5 cm (c). Earth’s atmosphere not only contains the air that we breathe but also protects it from the blasts of meteors that are constantly being hurtled towards it. 130) The atmosphere of Venus contains mostly SCSS: SCSS or SASS is a CSS pre-processor and gives you extra functionalities to work with CSS. Of the very small percentage of the universe that is made up of baryonic material, the most abundant element is hydrogen. The Law of Periods: The square of the period of any planet is proportional to the cube of the semimajor axis of its orbit. Chemistry refers to different materials, and physical properties refers to such things as whether the materials are solids or liquids, etc. Use data to draw conclusions about the major components of the universe 0607.6.1 Links verified 7/25/2014. (c) Quasar. 111) The comet known as Halley’s Comet has an average period of: 135) Why do we see lunar eclipses much more often than solar eclipses? 144) What is the HOTTEST region of the sun? In fact, the situation is significantly more indistinct and unsettled than most realize. The CSS Point is the Pakistan 1st Free Online (d) 86 years (b) Mars and Venus (b) Copernicus Answer: (a) 125) Of the following, which is the only planet which CANNOT be seen with the unaided eye? In a refracting telescope, the objective lens is the first lens the light passes through. Answer: (b) (a) change from night to day. Albedo is a measure of the reflectivity of a surface. The last manned landing Apollo 17 on the Moon to date, which took place on December 11, 1972, was made by Commander Eugene Cernan and lunar module pilot Harrison Schmitt who was also the first scientist on the Moon. These are what make up the Web Components specification. Answer: (c) Origin of Universe Theories: 1.

A CSS rule-set consists of a selector and a declaration block: The selector points to the HTML element you want to style. islamiat lectures; past papers of islamiat; english precise & composition. (a) Planets The Universe is vast. About 73% of the Sun’s mass is hydrogen, and another 25% is helium. All those planets found within the Inner Solar System – Mercury, Venus, Earth and Mars – are examples of terrestrial planets. This is defined in the Living Standard DOM specification. (a) Pallas. Earth has the highest density of any planet in the Solar System, at 5.514 g/cm3. 149) According to Kepler’s Laws, all orbits of the planets are: * Normal non-luminous matter (black holes and intergalactic gas): 3.6% * Dark Matter: 21% * Dark Energy: 75% 1.1 Normal matter forms 4% of the universe and is made up of atoms of chemical elements. Answer: (b), 119) A device which would not work on the Moon is: Lunar eclipses are more widely visible because Earth casts a much larger shadow on the Moon during a lunar eclipse than the Moon casts on Earth during a solar eclipse.

In the case that lower-energy hydrogen, hydrinos, comprises the dark matter, all matter is ordinary (baryonic) matter, and the mass of the Universe is sufficient for it to be closed [30, 31]. At a relatively smaller scale, we know that galaxies are made up of stars and their constituents, our own Solar System being one of them. In astronomy, an astronomical unit is defined as the average distance from the Sun to the Earth, or about 150 million kilometers (93 million miles). Energy :- sources and resources of Energy Energy conservation. Since the distances in astronomy are so vast, astronomers use this measurement to bring the size of numbers down.
