Scientists determine the masses of planets by observing the effect of the gravitational
field of those planets on nearby objects - mainly upon their moons. By measuring the
orbital period and orbital radius of a moon about a planet, Newton's laws of motion can
be used to determine the mass of the planet. Phobos, a moon of the planet Mars, was
discovered in 1877. Its orbital radius is 9380 km and its orbital period is 0.319 days (2.77
x 104 seconds). Determine the mass of Mars based o this data.

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
