Amy made the table shown to describe two processes. Amy's Table Process A: A rock crumbles easily when oxygen reacts with some substances present in the rock

Process B: Plants grow through the cracks in rocks and break the rocks apart

Which statement is true about the processes described in the table?

A. Both Process A and Process B represent physical weathering.
B. Both Process A and Process B represent chemical weathering.
C. Process A is physical weathering and Process B is chemical weathering.
D. Process A is chemical weathering and Process B is physical weathering.

The answer should be a.

Perhaps seek some professional ? it isn't very asking some children who are just trying to find out answers to homework.also, it seems professional would actually be good to you. obviously it isn't going to magically fix your depression, but it'll do something. drugs, smoking weed, it won't do much, especially if your husband is against it. if you do it he'll dislike it. but talk to him, try and get him to listen to you, and figure everything out together, okay? there's a website- maybe it can offer some ?

The figure is missing but we can answer anyway.the correct answer is "releasing the string". in fact, when the person is holding the bow and the arrow, the kinetic energy of the arrow is still zero (because the arrow is not moving). the moment the arrow is released, it acquires a velocity v, so its kinetic energy will become different from zero: where m is the mass of the arrow and v its velocity.  all the other options, instead, do not increase the kinetic energy of the system: -  pulling farther back on the string : this will just increase the elastic potential energy of the system-  holding the arrow higher: this will increase the gravitational potential energy of the system (which is given by u=mgh, where h is the height above the ground)-  decreasing the mass of the arrow: this will decrease the gravitational potential energy of the system (which is given by u=mgh, where m is the mass)
