Task 1: Universal gravitation andgravitational fieldsAnswer both parts with a complete solution.A complete solution means that you haveprovided the Given, Required, Analysis,Solution and Statement. Be sure that youcommunicate your final answer withappropriate units and the correct number ofsignificant figures.1. The earth has a mass of5.98 × 1024 kg and the moon has amass of 7.35 × 1022 kg. Thedistance from the centre of the moon tothe centre of the earth is3.84 × 109 m. A rocket with a totalmass of 1,200 kg is 3.0 × 108 m fromthe centre of the earth and directly inbetween the earth and the moon. Findthe net gravitational force on the rocketfrom the earth and moon.2. A 500 kg satellite experiences agravitational force of 3,000 N, whilemoving in a circular orbit around theearth.a. Determine the radius of the circularorbit.b. Determine the speed of the satellite.c. Determine the period of the orbit.

(a) What is the approximate force of gravity on a 70kg person due to the Andromeda galaxy, assuming its total mass is 1013 than of our Sun and acts like a single mass 2 Mly away? (b) What is the ratio of this force to the person's weight? Note that Andromeda is the closest large galaxy.
In what frame(s) of reference are Kepler's laws valid? Are Kepler's laws purely descriptive, or do they contain causal information?
A neutron star is a cold, collapsed star with nuclear density. A particular neutron star has a mass twice that of our Sun with a radius of 12.0 km. (a) What would be the weight of a 100-kg astronaut on standing on its surface? (b) What does this tell us about landing on a neutron star?
The CERN particle accelerator is circular with a circumference of 7.0 km. (a) What is the acceleration of the protons (m=1.671027kg)that move around the accelerator at 5of the speed of light? (The speed of light is v=3.00108m/s .) (b) What is the force on the protons?
Check Your Understanding Why not use the simpler expression U=mg(y2y1) ? How significant would the error be? (Recall the previous result, in Example 13.4, that the value g at 400 km above the Earth is 8.67m/s2 .)
What is the relationship between weight and mass? Which is an intrinsic, unchanging Property of a body?
Check Your Understanding Consider the density required to make Earth a black hole compared to that required for the Sun. What conclusion can you draw from this comparison abut what would be required to create a black hole? Would you expect the Universe to have many black holes with small mass?
(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) . After landing on the planet Mars, two astronauts awaken from a long induced hibernation inside their windowless spacecraft. Before emerging, is there any way they can determine whether their individual body weights are the result of gravitation or accelerated motion?
Describe the basic features of the “lighthouse” model of a pulsar, and indicate how they combine to give rise to the observed sharply pulsed radio emission from these sources.
Since 1995, hundreds of extrasolar planets have been discovered. There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star. The semimajor axis of an extrasolar planet is inferred from its period. What range in periods corresponds to the habitable zone for an Earth-like Planet orbiting a Sun-like star?
Check Your Understanding Galaxies are not single objects. How does the gravitiational force of one galaxy exerted on the “closer” stars of the other galaxy compare to those farther away? What effect would this have on the shape of the galaxies themselves?
What is the orbital radius of an Earth satellite having a period of 1.00 h? (b) What is unreasonable about this result?
