Q: what happens to the skydiver's velocity and acceleration when the skydiver reaches terminal velocity?
answer choices:
a) the sky diver does not reach terminal velocity
b) after reaching terminal velocity, the sky diver's velocity remains constant, so her acceleration is zero
c) after reaching terminal velocity, the sky driver's velocity decreases
d) after reaching terminal velocity, the sky driver's velocity increases

Once the parachute is opened, the air resistance overwhelms the downward force of gravity. The net force and the acceleration on the falling skydiver is upward. ... The skydiver thus slows down. As the speed decreases, the amount of air resistance also decreases until once more the skydiver reaches a terminal velocity, Thus concludes me to say The correct answer is: Answer B

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
