Suppose a 1.55 × 10-kg airplane has engines that produce 85 mw of power. 33%
part (a) how many seconds would it take the airplane to reach a speed of 275 ms and an altitude of 10.5 km, if air resistance were negligible? 33%
part (b) how much power did the plane use, in megawatts, if this process actually took 825 s? -* 33%
part (c) using the power consumption from part (b), what would be the magnitude of the average force, in newtons, of the air resistance if the airplane took 1175 s and traveled in a straight line at a constant acceleration to the specified altitude?

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
