All of the following statements about the relationship between stress and performance are false, except: a. as stress levels increase from low to moderate, performance decreases b. as stress levels increase from low to moderate, performance increases c. as stress levels decrease from moderate to low, performance stays the same d.

b. as stress levels increase from low to moderate, performance increases

Explanation:

From research, the relationship between stress and performance takes the the form of a bell curve. As stress increases performance also increases.

Maximum performance is observed at the optimal level of stress. However, any more stress beyond this point causes loss in productivity. There are psychological tests that can be taken to determine a person's stress level.

vestigial organs (like your appendix) are organs that no longer serve a purpose.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
