Find the orbital speed of an ice cube in the rings of Saturn. The mass of Saturn is 5.68 x 1026 kg, and use an orbital radius of 1.00 x 105 km. (G = 6.67 × 10-11 N ? m2/kg2 )
A) 19.5 km/s B) 27.5 km/s C) 13.8 km/s D) 9.40 km/s
A heavy dart and a light dart are launched horizontally on a frictionless table by identical ideal springs. Both springs were initially compressed by the same amount
Which of the following statements about these darts are correct? (There could be more than one correct choice.) A) The darts both have the same kinetic energy just as they move free of the spring. B) The lighter dart leaves the spring moving faster than the heavy dart. C) The heavy dart had more initial elastic potential energy than the light dart. D) Both darts move free of the spring with the same speed. E) Both darts had the same initial elastic potential energy.
A current-carrying ohmic metal wire has a cross-sectional area that gradually becomes smaller from one end of the wire to the other. The current has the same value for each section of the wire, so charge does not accumulate at any one point. How does the resistance per unit length vary along the wire as the area becomes smaller?
1.It increases. 2.It decreases. 3.It remains constant.
Suppose that Hubble's constant were 11 km/s/million light-years instead of 22 km/s/million light-years. How would this graph look different?
A) The data would follow a much steeper, almost vertical line. B) The data would follow a more shallow line, closer to horizontal than the current line. C) The data would follow a flat, horizontal line. D) The graph would have to show luminosity on the vertical axis, rather than velocity.
