1. Compute the period of a satellite placed into orbit around the Earth at a distance of tenth that to the Moon.
2. The local solar time at 75°W is 12:00 noon. What is the longitude of an observer who sees the full moon on her meridian at this time?
3. At what longitude is an observer who sees the last-quarter moon on his meridian when I is 12:00 noon local solar time at 75°W?
4. It is 12:00 noon local solar time at 75°W. The date is March 21.At what longitude would an observer be able to see the last-quarter moon rising?
5. A high tide is occurring at Charleston, S.C. (80°W, 33°N). At approximately what other longitude is a high tide occurring?
6. A high tide is occurring at Charleston, S.C. (80°W, 33°N). What two longitudes are experiencing low tide?
7. The Ulysses space probe of the Sun encountered the planet Jupiter in 1998 and returned to make a second sweep over the Sun's poles in 2000-2001. Determine the time (in seconds and minutes) it takes a radio signal to reach the Earth when the space probe was at Jupiter. (Use 778 × 106 km for the distance from the space probe to Earth. The distance varies because the Earth and Jupiter are orbiting the Sun.)
Wire is often delivered wrapped on a large cylindrical spool. Suppose such a spool is supported by resting on a horizontal metal rod that is pushed through a hole that runs through the center of the spool. A worker is pulling some wire off the spo..
In a lightning bolt, a large amount of charge flows during a time of 2.1 x 10-3 s. How much charged has flowed during the lightning bolt?
The cable supporting a 1950 kg elevator has a maximum strength of21920 N. What maximum upwardacceleration can it give the elevator without breaking
A mountain climber, in the process of crossing among two cliffs by a rope, pauses to rest. She weighs 555 N. She is closer to the left cliff than to 2 the right cliff, with the result that the tensions in the left and the right sides of the rope are..

A package is dropped from a passing plane (moving in the horizantal direction) and produces a projectile motion as it is falling to the ground. If it takes the package only 32.12 seconds until it hits the ground, how far above the ground was the plan..
In recent years, a number of nearby stars have been found to possess planets. Suppose, the orbital radius of such a planet is found to be 3.1 1011 m, with a period of 1140 days
An electron is located on the x axis at x0 = -9.31 × 10-6 m. Discover the magnitude and direction of the electric field at x = 9.39 × 10-6 m on the x axis due to this electron. What is the magnitude in N/C? Is the direction positive x direction, nega..
