Imagine an eel swimming by a hydrothermal vent 7,700 m below the ocean's surface. Which deformation modulus would be used to describe the forces acting on the eel? What would you expect to happen if you brought the eel up to the surface?

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.

Independent variable is something that is changed in a experiment. 

The correct answer is  "c".  it is "c" because melting is an endothermic change, and endothermic get's energy from surroundings.
