pickaxe while trying to dig a hole. If
the pickaxe strikes with a force of
2000 N and the end of the pickaxe
measures 0.02 m by 0.01 m, how much
pressure is exerted on the pipe by the
pickaxe?

Which statement best explains why an object weight less on mercury than it does on earth

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.
