Answer:
There are two methods generally used to magnetize permanent magnets: static magnetization and pulse magnetization.
Answer:
Explanation:
Initial angular velocity ω₁ = 0 , final angular velocity ω₂ = 75.9 rad /s
angle rotated = θ
= 37 x 2π
= 74 π
The formula for angular velocity
ω₂² = ω₁² + 2αθ , α is angular acceleration
75.9² = 0 + 2 α x 74 π
α = 75.9² / 2 x 74 π
= 12.396 rad / s²
You don't need to do any calculations, you are already given that n=1.5
n is index of refraction. it's 1.5
