The Sun is in the center of Solar System and is composed mainly of the elements (1) and (2). The distance from the Earth to the Sun is also called (3). Many people dream about building a colony on Mars, but the atmosphere is primarily made of (4). We have discovered the (5) between Mars and
Jupiter, which contains millions of small objects. Jupiter has a total of (6) moons: The four largest moons are easily visible with a telescope and(7) is the closest and most active one. Uranus and Neptune are the outermost planets and it takes Neptune (8) years to complete one orbit around the Sun.

Find the magnetic field a distance r from the center of a long wire that has radius a and carries a uniform current per unit area j in the positive z direction.

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?
