An astronaut holding on outside the space station lets go. What happens? Group of answer choices The astronaut and space station travel together, because the gravity of the space station attracting the astronaut cancels their difference in mass. The astronaut orbits along with the space station, because the astronaut and space station have the same velocity. The astronaut’s orbit moves further from the earth, because the force of gravity is smaller for less massive objects. The space station falls behind the astronaut, because lighter objects orbit faster. The astronaught’s orbit moves farther from the Earth, because the space station has lower angular momentum.

If the equation F(x,y,z) = 0 determines z as a differentiable function of x and y, then, at the points where Fz ? 0, the following equations are true. \frac{dz}{dx} = -\frac{F_x}{F_z} and \frac{dz}{dy} = -\frac{F_y}{F_z} Use these equations to find the values of dz/dx and dz/dy at the given point z^3 - 5xy + 5yz + 2y^3 - 155 = 0, (3, 4, 3) \frac{dz}{dx}|_{(3,4,3)} = \boxed{} (Type an integer or a simplified fraction) \frac{dz}{dy}|_{(3,4,3)} = \boxed{} (Type an integer or a simplified fraction)

15. Suppose you have two colorless molecular liquids A and B whose boiling points are 78 °C and 112 °C respectively and both are at atmospheric pressure. Please decide whether each sentence is correct or incorrect. If incorrect, explain briefly. (each 2 pt) (a) Both A and B are liquids with identical vapor pressure at room temperature of 25 °C. (b) Liquid A must consist of nonpolar molecules with lower molecular weight than B. (c) Both liquids A and B have higher total intermolecular forc than water. (d) Liquid A is more volatile than liquid B because it ha lower boiling point. (e) At 112 °C both liquids have a vapor pressure of 1 atm.
