15 Points What is the acceleration of gravity on the surface of the Sun? What is the Force of Gravity between Neptune and the Sun? How fast is the orbital velocity of Neptune? What is the time period of Neptune’s Orbit? (Express your answer in Earth Days) Neptune mass = 1.03 x 1026 kg radius = 2.5 x 107 m orbital distance = 4.5 x 1012 m Sun mass = 2.0 x 1030 kg radius = 6.970 x 108 m

A “cell” with a selectively permeable membrane contains 0.02 M sucrose, 0.01 M glucose, 0.04 fructose, and 0 M lactose. It is immersed in a solution consisting of 0.05 M sucrose, 0.03 M glucose, 0.01 M fructose, and 0.03 M lactose. The membrane is permeable to water and to the simple sugars glucose and fructose, but is impermeable to the disaccharides sucrose and lactose. 45 minutes after being placed into the beaker, which of the following changes would occur?
