The radius of Saturn is 58,232 km. The radius of Mercury is 2,440 km. If you flew from the surface of Saturn to the surface of Mercury, you would travel a distance of 1,366,690,000 km.
Use this information to calculate the value used in determining the Force of gravity between the two planets.

Asimply means that over time there was some sort of change.

Ammonia enters the expansion valve of a refrigeration system at a pressure of 10 bar and a temperature of 18oc and exits at 6.0 bar. the refrigerant undergoes a throttling process. determine the temperature, in oc, and the quality of the refrigerant at the exit of the expansion valve.

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?
