The weight of spaceman speff at the surface of planet x, solely due to its gravitational pull, is 389 n. if he moves to a distance of 1.86 × 104 km above the planet's surface, his weight changes to 24.31 n. what is the mass of planet x, if speff's mass is 75.0 kg? (g = 6.67 × 10 -11 n ∙ m2/kg2)

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
