Can I install Microsoft Office 2010 on both my desktop PC and my laptop if they both belong to me? plan to buy a PC next January. Can I buy the 2010 Office business version (which permits 2 activations-on my primary PC and my laptop) and install it first on my new laptop and later install it on my primary PC after I buy it next Jan? In other words, does it matter what sequence I install the software?
Confidence votes 12. If an Earth-like planet was orbiting at the same distance from its double solar mass star as the Earth is from the Sun (1 astronomical unit, written 1 AU), then the force would be double that experienced by the Earth.he force at constant distance is just proportional to the product of stellar and planetary masses. We don't know of any reason why an Earth mass planet should not form at 1 AU from a star of 2X Solar mass, though we as yet have few observational measurements of such low mass extra-solar planets.
Robert Burnham noticed that, quite by coincidence, the number of astronomical units in one light-year and the number of inches in one mile are virtually the same. For general reference, there are 63,000 astronomical units in one light-year, and 63,000 inches (160,000 cm) in one mile (1.6 km). This wonderful coincidence enables us to bring the light-year down to Earth.
