For what values of θ are the magnitudes of the scalar product and the vector product equal? express your answers in degrees using three significant figures. enter positive values from 0∘ to 180∘ in ascending order separated by a comma.

45°

Explanation:

Let there are two vectors, A and B. The angle between the two vectors is θ.

The dot product of two vectors is equal to the vector product of two vectors.

A B cosθ = A B Sinθ

tan θ = 1

θ = 45°

Thus, the angle between the two vectors is 45°

answer: he got 23

explanation:

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
