An astronomer records over several nights the change in position of Venus and then calculates that Venus orbits the Sun once every 110 Earth days. This figure is considerably lower than the 225 Earth-day orbit that is widely
accepted for Venus. What should the astronomer do next?
O publish the findings to reveal the flaw in current orbital theories
o gather a new set of data and see if the results remain the same
add 115 days to the calculations to match the current published data
o form a hypothesis to explain how the orbit of Venus can vary so greatly

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?
