Question 3 Which of the following best explains why we can rule out the idea that planets are usually formed by near-collisions between stars? Stellar near-collisions are far too rare to explain all the planets now known to orbit nearby stars. Question 4 According to our present theory of solar system formation‚ which of the following objects now reside quite far from the place where they

    pressure is due not to static repulsion between molecules‚ as was Isaac Newton’s conjecture‚ but due to collisions between molecules moving at different velocities through Brownian motion. While the particles making up a gas are too small to be visible‚ the jittering motion of pollen grains or dust particles which can be seen under a microscope‚ known as Brownian motion‚ results directly from collisions between the particle and gas molecules. As pointed out by Albert Einstein in 1905‚ this experimental

    OHM’S LAW INTRODUCTION Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference or voltage across the two points‚ and inversely proportional to the resistance between them provided the temperature remains constant. The mathematical equation that describes this relationship is: where V is the potential difference measured across the resistance in units of volts; I is the current through the resistance in units of amperes and

    formation is gravitational collapse – the contraction of a region of gas under the influence of gravity. This is a simple process that would be expected to occur in any region of material dense enough for collisions between atoms to radiate away energy. However‚ the gas must be dense enough for collisions to occur and the temperature must be low enough for the atomic velocities not to be able to escape the system’s gravity‚ so star formation only occurs in a few areas. The sites of star formation in

    situation is‚ he agrees to gather a team and carry out the plan. In February 2010‚ 2005YU55 was rated 1 on the Torino Scale. This scale is defined as scale from 0 to 10. A 0 indicates an object has a negligibly small chance of collision with the Earth and A 10 indicates that a collision is certain‚ and the impacting object is large enough to precipitate a global disaster. On the 19th of April 2011 highly accurate radar lowered the possibilities by a 50% of 2005YU55 impacting our planet earth. 2005 YU55
