1. The figure shows a mass hanging from the ceiling. Find the tension in each of the three strings that hold the dough.

2. Two blocks of mass 3.5 kg and 8.00 kg are connected by a rope without mass passing over a
frictionless pulley. Inclined planes are frictionless. a) Determine the magnitude of the acceleration
of each block, and b) the tension in the rope.

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.
