Why does sound travel more quickly through cold water than warm water?

The molecules move more quickly in cold water, making sound transmit more quickly.

Sound does not travel more quickly through cold water.

The molecules in cold water being closer together means sound has less distance to travel.

The more rapid motion of warm water disrupts the transmission of sound.

After the near spacecraft passed mathilde, on several occasions rocket propellant was expelled to adjust the spacecraft's momentum in order to follow a path that would approach the asteroid eros, the final destination for the mission. after getting close to eros, further small adjustments made the momentum just right to give a circular orbit of radius 45 km (45 × 10^3 m) around the asteroid. so much propellant had been used that the final mass of the spacecraft while in circular orbit around eros was only 545 kg. the spacecraft took 1.04 days to make one complete circular orbit around eros. calculate what the mass of eros must be.
