Since scarcity is when the supply of a product goes low
the price goes up when the supply of a product is down
The speed of a wave measures how far one particular crest (or trough) moves in a given amount of time. The speed of the wave changes according to the following equation:
v = λ
* f
According this equation, it follows that as the speed and length of a wave decreases, the wave grows higher (the higher the frequency).
Mesosphere is the layer after stratosphere, which is after troposphere, as seen from Earth in the direction of Space.
It starts at 60 km and ends at 120 km, after which comes the termosphere.
So we're looking for a line that's closest to 100 km, and this is the shortest line, A.
It would be d. all of the above because precipitation means rain, and when it rains the water replenishes also streams and rivers replenish water by allowing water to flow.
