#1) (A) Issac Newton's Law of Universal Gravitation is: Two bodies attracted to each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This means that the further apart these two attracting bodies are from each other, the less the gravitational force between them is. The force of gravity depends on the product of the mass of the two attracting bodies. If the distance between the two bodies doubles, the force between them becomes one quarter of the force it was before. The Law of Universal Gravitation is vital because it mathematically proves Kepler's Three Laws of Planetary Motion. The Planets follow the same laws of motion as objects on the surface of the earth. (B) Newton discovered other types of orbits that have circular of elliptical paths. However, if the velocity of an orbiting body were increased, its orbital path would change to a parabola or hyperbola and it would escape the gravitational pull of the sun. It would then leave the solar system. Parabolas are the orbital paths of objects in the form of an open curve. If one cuts out an angle in a circular cone, it would follow this path p
(C) Venus - The surface of Venus appears to be smooth with rolling plains and some high and low land features. 4) He also was the first to see sunspots on the sun. This series of spectral lines are called the Lyman Series. The star, 47 Ursae Majoris, is about 44 light years from Earth and the planet that orbits this star takes approximately three years to complete a full rotation around the star. When one of the electrons drops down to a lower level, a photon is emitted. The atmosphere of Venus has a massive strength of about 90 times that of Earths and its level is found at an attitude of 50 km. (B) Four scientifically important parameters that can be sensed by spectroscopes attached to observational telescopes are: 1) Physical conditions of an object. For example: Moon's that orbit planets, such as the four Galilean Moons that orbit Jupiter. This thickness slows the light waves as they pass through the glass, bringing the waves into focus at the same time. Mercury has many craters, but it has very little lava flow regions, which we call scarp. He believed that the wavelength of the light of a star that is moving away from us (Earth) would be lengthened which would make the light more red. However, spherical aberration can still occur because when light enters a telescope with a spherical mirror at different distances from the mirror's center, the light comes into focus at different focal lengths. (B) Mercury- This planet is difficult to observe from Earth with current technology because of its closeness to the sun.
