The mass of Jupiter is 300 times the mass of the earth. Jupiter orbits the sun with TJupiter = 11.9 yr in an orbit with rJupiter = 5.2rearth. Suppose the earth could be moved to the distance
of Jupiter and placed in a circular orbit around the sun. Which of the following describes the earth鈥檚 new period?
Explain.
a. 1 yr
b. Between 1 yr and 11.9 yr
c. 11.9 yr
d. More than 11.9 yr
e. It would depend on the earth鈥檚 speed.
f. It鈥檚 impossible for a planet of earth鈥檚 mass to orbit at the
distance of Jupiter.
In Problems 64 through 66 you are given the equation(s) used to solve a problem. For each of these, you are to
a. Write a realistic problem for which this is the correct equation(s).
b. Draw a pictorial representation.
c. Finish the solution of the problem.
Nothing can escape the event horizon of a black hole, not even light. You can think of the event horizon as being the distance from a black hole at which the escape speed is the speed of light, making all escape impossible. What is the radius of the event horizon for a black hole with a mass times the mass of the sun? This distance is called the Schwarzschild radius.
A starship is circling a distant planet of radius R. The astronauts find that the free-fall acceleration at their altitude is half the value at the planet鈥檚 surface. How far above the surface are they orbiting? Your answer will be a multiple of .
In , NASA placed a satellite in orbit around an asteroid. Consider a spherical asteroid with a mass of and a radius of

b. What is the escape speed from the asteroid?
