ASAP I will give 34 points please give a good answer Below is an image of a well. Explain what type of well this is and how it works.

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2

What is the average speed of a car that travels 40 mph for 1 hour and 60 mph in another hour?

The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?
