Both please help 81. The Navstar Global Positioning System (GPS) utilizes agroup of 24 satellites orbiting the Earth. Using "triang-ulation" and signals transmitted by these satellites, theposition of a receiver on the Earth can be determined towithin an accuracy of a few centimeters. The satellite orbitsare distributed around the Earth, allowing continuousnavigational "fixes." The satellites orbit at an altitudeof approximately 11,000 nautical miles [1 nautical mile =1.852 km = 6076 ft]. (a) Determine the speed of eachsatellite. (b) Determine the period of each satellite.82. The Near Earth Asteroid Rendezvous (NEAR) spacecraft,after traveling 2.1 billion km, is meant to orbit the asteroidEros with an orbital radius of about 20 km. Eros isroughly 40 km×6 km × 6 km. Assume Eros has a density(mass/volume) of about 2.3 x 10 kg/m³. (a) If Eroswere a sphere with the same mass and density, what wouldits radius be? (b) What would g be at the surface of aspherical Eros? (c) Estimate the orbital period of NEARas it orbits Eros, as if Eros were a sphere.
