The quantities v, k, u, and l all represent physical quantities characterizing the orbit that depend on radius r. indicate the exponent (power) of the radial dependence of the absolute value of each. express your answer as a comma-separated list of exponents corresponding to v, k, u, and l, in that order. for example, -1,-1/2,-0.5,-3/2 would mean v∝r−1, k∝r−1/2, and so forth.

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !

The average density of the planet uranus is 1.27 103 kg/m3. the ratio of the mass of neptune to that of uranus is 1.19. the ratio of the radius of neptune to that of uranus is 0.969. find the average density of neptune.

As the distance from a magnet increases, what happens to the magnet force?
