Andre is finding working in an online group challenging because there are people in the group from many different cultural backgrounds. Which are the three major areas that present challenges to students in such situations? ANSWER THAT'S NOT THE SAMPLE!! : They have different styles of communication, approach on completing things in different manners, they have different views in knowledge, and could handle time sensitive projects in different ways whether it be stressful, easy, or just ignore it completely.

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)

D) the event horizon, a large planet and the chute located between the two.
