Scientists have just discovered a new moon for planet X at the far edge of the Milky Way. Which statement is the best summary of what scientists know about gravitational attraction and the new moon? (Select one of the following):
A. The moon is only gravitationally attracted to the planet X.
B. There are countless relationships of gravitational attraction between the moon and the other bodies in the solar system.
C. The moon is only gravitationally attracted to our sun.
D. None of these can be assumed. The scientists must conduct experiments to test these ideas.

In our derivation of Kepler's laws, we assumed the only force on
a planet is due to the Sun. In a real solar system, however, the
gravitational forces from the other planets can sometimes be
important. Calculate the gravitational force of Jupiter on the
Earth. Do the calculations for the cases when Jupiter is both
closest (Fc) to and farthest
(Ff) from the Earth (see the figure below).

Physics Lab Assignment This particular discovery is also an example of how those who deserve an award sadly are not always the ones who receive it. Read the following passage focusing your attention on the scientific procedures and scientific abilities you have been developing throughout the course. The discovery of pulsars –rotating neutron stars that generate regular pulses of radiation at their spin rate- was fortuitous. A group of astrophysicists from Cambridge University lead by Anthony Hewish was looking for...

The discovery of pulsars –rotating neutron stars that generate regular pulses of radiation at their spin rate- was fortuitous. A group of astrophysicists from Cambridge University lead by Anthony Hewish was looking for quasars (these are extremely bright, compact and remote objects that emit up to a thousand times as much light as our entire galaxy). For that purpose the research group designed a radio-telescope that was built on the flat fields surrounding Cambridge in central England. This telescope did...
