The Roche limit is the closest distance an object can approach a planet before being torn apart by the tidal attraction of the planet. For a rigid spherical moon the Roche limit is given by Eq. (6) in Box 2.1. (a) Using the planetary dimensions in Table 1.1, cal- culate the Roche limit for the Moon with respect to the Earth. Express the answer as a multiple of the Earth's radius.

In January 2006 astronomers reported the discovery of a planet, comparable in size to the earth, orbiting another star and having a mass about 5.5 times the earth’s mass. It is believed to consist of a mixture of rock and ice, similar to Neptune. If this planet has the same density as Neptune 11.76 g>cm32, what is its radius expressed (a) in kilometers and (b) as a multiple of earth’s radius?
(a) How many seconds are there in a year?

(Hint: Consider a cubic box, 1 m on aside, on the Moon, and find how long it would take to fill the box.)

A student from Isabela State University launched a rocket that has a payload of atmospheric sensors. The payload contains an altimeter and a digital barometer. From one of the University’s class room where they built a data receiving area, the altimeter sends 10 values of altitude, 5600 ft, 5000 ft, 4600ft, 4100 ft, 3800 ft, 3500 ft, 3150 ft, 2900 ft, 2300 ft, and 1300 ft. But the data of the barometer wasn’t sent because of a circuit anomaly. But the programmer assured that it will be recorded in the memory inside the payload’s microcontroller. Assuming the air density to be 1.18 ??/?3, what pressure we should expect depending on the data sent by the altimeter?
