The Faraday Ice Pail used during the experiment has two wire mesh cylinders. Briefly explain what their functions were for the experiment. Think about the leads from the charge sensor and which color (black or red) was connected to which cylinder.

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.

What is the fate of the electrons that interact with a specimen in an electron microscope?

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.
