At a given instant, the geocentric equatorial position vector of an earth satellite is r1 ¼ 3600^i þ 4600^j þ 3600^k ðkmþ thirty minutes later, the position is r2 ¼ 5500^i þ 6240^j 5200^k ðkmþ find the specific energy of the orbit.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)

hi,

what occurs during a solar eclipse?

there are small tides across earth.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
