Answer! will mark brainliest! which of the following is most likely to form when hot magma rises up as tectonic plates move apart below the ocean? mid-ocean ridge fault trenches subduction zone

a) α = 1.875

b) t = 8 s

Explanation:

Given:

ω1 = 0

ω2 = 15

theta (angular displacement) = 60 rad

*side note: you can replace regular, linear variables in kinematic equations with angular variables (must entirely replace equations with angular variables)*

a) α = ?

(ω2)^2 = (ω1)^2 + 2α(theta)

= + 2(α)(60)

225 = 120α

α = 1.875

b)

α = (ω2-ω1)/t

t = (ω2-ω1)/α = (15-0)/1.875 = 8

t = 8 s
