The Hubble Space Telescope orbits the Earth at an altitude of approximately 612 km. Its mass is 11,100 kg and the mass of the Earth is 5.97×1024 kg. The Earth's radius is 6.38×106 m. Assume the Hubble's orbit is circular. (a) What is the gravitational potential energy of the Earth-Hubble system? (Assume that it is zero when their separation is infinite.) (b) What is the Hubble's KE? (c) What is the Hubble's total energy?
3. The Hubble Space Telescope has an aperture of 2.4 m and focusesvisible light (400-700nm). The Arecibo radio telescope in PuertoRico is 305m in diameter and focuses radio waves of wavelength 75cm.a. Under optimal viewing conditions, what is the smallest craterthat each of these telescopes could resolve on the moon?b. Of the Hubble Space telescope were to be converted tosurveillance use, what is the highest orbit above the surface ofthe Earth it could have and still be able to resolve the licenseplates (just the plates, not the letters) of a car on theground?
The space station orbits at an average height of 350km above thesea level.
A) determine the acceleration due to gravity at that height andfind the orbital velocity and the period of the space station.
B) the hubble teloscope orbits at 600km. what is the telescopesorbital velocity and period?
