To find the displacement between t=0 and t=1, we want to plug 0 & 1 into the equations, then find the different in the answers.
<u>When t = 0:</u>
x = 4 cos(π(0)+π/4) → π · 0 = 0, so therefore:
x = 4 cos (π/4) → cos (π/4) = √2/2
x = 4 (√2/2)
x = 4√2/2 → 4 divided by 2 = 2, so we can simplify this to
x = 2√2
<u>When t = 1:</u>
x = 4 cos(π(1)+π/4) → π · 1 = π, so therefore:
x = 4 cos (π + π/4) → π + π/4 = 5π/4, so therefore
x = 4 cos (5π/4) → cosine of 5π/4 = -√2/2
x = 4 · -√2/2
x = -4√2/2 → -4 divided by 2 = -2, so we can simplify this to
x = -2√2
<u>Answer</u>: Then, we find the difference between x(0) and x(1), which is x(1)-x(0) =
-√2/2 - √2/2 = <u>-√2</u>
Here are some points that could be used :
1. seceding would reduce the amount of resource that the nation as a whole had, so the federal government shall not allowed it to happen.
2. Many people in the population might not agree to the secession so the government had to protect their interest,
3. Secession make our nation become much more vulnerable to attacks, since foreign nations can leverage the separation to gain allied that close to us.
Answer:
Endorphins.
Explanation:
Endorphins are a substance produced by the pituitary gland, whose function is to stabilize the feelings of well-being of the body when performing certain activities, such as those that include physical effort, or even when experiencing pain sensation, where endorphins work as analgesics that slow down the sensation of pain.
