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.
Imagine taking a trip at the speed of light. The ultimate speed limit according to Einstein's Theory of Special Relativity; c = 186,000 miles/sec = 300,000 km/s = 3 x 10 10 cm/s (= 1 light-year/year). The effects of Special Relativity will have a profound effect upon space travel.
