In 1983 there were 100,000 transistors on a typical computer chip. (a) by moore's law, in which year we should have had 6.4 million transistors on a chip of same size? (b) if the size of the chip was 1cm x 1cm, what was linear size of the transistor in 1983 and later when there were 6.4 million transistors on the chip?

Asailboat is traveling to the right when a gust of wind causes the boat to accelerate leftward at 2.5m/s2 for 4s. after the wind stops, the sailboat is traveling to the left with a velocity of 3.0m/s. assuming the acceleration from the wind is constant, what was the initial velocity of the sailboat before the gust of wind? answer using a coordinate system where rightward is positive.
