seven naked-eye objects that appear to move among the constellations.most popular Norse gods.4/14
-seven largest constellations of the ancient world.Question 121 / 1 pointKepler’s third law of planetary motion states thatthe semi­major axis of a planet’s orbit is directly proportional to the cube of its periodofmotion around the Sun.the square of the semi­major axis of a planet’s orbit is directly proportional to the cube ofitsperiod of motion around the Sun.the cube of the semi­major axis of a planet’s orbit is directly proportional to the square ofitsperiod of motion around the Sun.the square of the semi­major axis of a planet’s orbit is directly proportional to its periodofmotion around the Sun.the semi­major axis of a planet’s orbit is directly proportional to its period of motionaroundthe Sun.Question 131 / 1 pointPtolemy was important in the history of astronomy because hewas the first to believe in an Earth-centred universe.was the first to believe that all orbits are perfect circles.was the first to create a model of the solar system that placed the Sun rather than the Earthat the centre.developed a model of the solar system that made sufficiently accurate predictions ofplanetary positions to remain in use for many centuries.developed the first scientific model of the universe.Question 141 / 1 pointGalileo observed that Jupiter has moons. From this information you may conclude thatJupiter orbits the Earth.Ptolemy’s vision of the solar system iscorrect.Jupiter orbits the Sun.5/14
-Group BJupiter is the centre of the solar system.some things do not orbit Earth.Question 151 / 1 pointUpon what quantities does angular momentum depend?Force and radiusThree quantitiesan object’s mass, its rotational speed, and its radius or distance fromtherotational centreMomentum and angular velocityJust the mass of the objectThree quantitiesan object’s weight, theacceleration of gravity, and its radiusQuestion 161 / 1 pointA green apple (nor your Mac computer) looks green becauseit transmits green light and emits all other colors.it reflects all colours but green light.it emits green light and absorbs all other colors.it absorbs green light and emits all other colors.it reflects green light and absorbs all other colors.Question 171 / 1 pointRadiative (or radiant) energy islight energy.any energy connected with motion.heat energy.energy used in home radiators.
-6/14
-energy from nuclear power plants.Question 181 / 1 pointSuppose that the Sun were to suddenly disappear from our solar system. What would happen toEarth’s motion?It would begin spiralling in toward the centre of the solar system.It would begin travelling in a straight line heading out of the solar system.
