Answer:

Explanation:
This is a projectile motion problem. We will first separate the motion into x- and y-components, apply the equations of kinematics separately, then we will combine them to find the initial velocity.
The initial velocity is in the x-direction, and there is no acceleration in the x-direction.
On the other hand, there no initial velocity in the y-component, so the arrow is basically in free-fall.
Applying the equations of kinematics in the x-direction gives

For the y-direction gives

Combining both equation yields the y_component of the final velocity

Since we know the angle between the x- and y-components of the final velocity, which is 180° - 2.8° = 177.2°, we can calculate the initial velocity.

If <em>the isotherms</em> are spaced closely together over some portion of the map, there is a drastic temperature change over that portion.
I would think A. Reduce Environmental Impacts.
If you build and populate more zoos, some of the endangered species might not be able to survive in captivity
If you introduce new predators they are going to kill all the endangered species and if you pass new laws about land use some people may kill the species
CORRECT ANSWER:
D. short-run; long run
STEP-BY-STEP EXPLANATION:
The whole question from book is
Evidence suggests that there may be _______ momentum and ________ reversal patterns in stock price behavior.
A. short-run; short-run
B. long-run; long-run
C. long-run; short-run
D. short-run; long run
Evidence suggests that there may be <em><u>short-run</u></em> momentum and <em><u>long run </u></em>reversal patterns in stock price behavior.
If the two waves have the SAME FREQUENCY and are exactly
out of phase (180° apart), then the resultant wave will have the
same frequency and an amplitude of 1 unit.
If the two waves do not have the SAME FREQUENCY, then their
relative phase is meaningless.
