Ductile deformation results in a change of the shape of solids without breaking them. this can also be said of elastic deformation. watch both the elastic deformation and ductile deformation topics in the reock deformation animation, and compare the two types of deformation. how is ductile deformation different from elastic deformation? choose one or more: a. once the stress is removed, rocks that have undergone ductile deformation return to their original shape. b. ductile deformation can result in tight folds, whereas elastic deformation usually terminates in brittle deformation rather than tight folding. c. once the stress is removed, rocks that have undergone ductile deformation retain their new shape. d. ductile deformation results in folds, whereas elastic deformation results in faults. e. ductile deformation requires internal fracturing of the rock, whereas elastic deformation does not.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
