For this problem, the applied force P must be calculated such that the allowable stress of 180 MPa is not exceeded in either wire. The correct choice for P will be: For this problem, the applied force must be calculated such that the allowable stress of is not exceeded in either wire. The correct choice for will be: The larger value The smaller value The values of P will be the same in either wire None of the above

we do not exceed that value, the force of having a value less than that calculated

Explanation:

Pressure is defined by

           P = F / A

           F = P A

           F = 180 10⁶ A

for an exact calculation the area of the wire is needed

So that we do not exceed that value, the force of having a value less than that calculated

therefore the correct answer is "a smaller value"

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

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
