The most important questions to study for the exam
... 21. Two stars are sufficiently far away from the Earth that they cannot be resolved as separate stars but orbit each other with a large separation between them compared to the stars' radii. Furthermore, their orbital plane is inclined at 45∞ to the direction to the Earth from the star system. What o ...

TRUE It is estimated that it took about 1 million years after the initial Big Bang before the first and simplest conventional atoms (hydrogen and helium) had formed. Because the emission of light only occurs when electrons which have jum ...

Gravitation and Orbital Motion
... gravitational pull of the Moon is partially responsible for the tides of the sea. The Moon pulls on you, too, so if you are on a diet it is better to weigh yourself when this heavenly body is directly overhead! If you have a mass of 85.0 kg, how much less do you weigh if you factor in the force exer ...

Star Formation
... A Star is Born • The protostar continues to collapse while the central core heats up to millions of degrees. • Fusion reactions start => A star is born What stops the collapse? • Collapse is halted by the pressure of the heated gas which balances gravity. ...
