The drawing shows three objects rotating about a vertical axis. the mass of each object is given in terms of m0, and its perpendicular distance from the axis is specified in terms of r0. rank the three objects according to their moments of inertia, largest to smallest.

I₁ > I₃ > I₂

Explanation:

Taking the pic shown, we have

m₁ = 10m₀

m₂ = 2m₀

m₃ = m₀

r₁ = r₀

r₂ = 2r₀

r₃ = 3r₀

We apply the formula

I = mr²

then

I₁ = m₁r₁² = (10m₀)(r₀)² = 10m₀r₀²

I₂ = m₂r₂² = (2m₀)(2r₀)² = 8m₀r₀²

I₃ = m₃r₃² = (m₀)(3r₀)² = 9m₀r₀²

finally we have

I₁ > I₃ > I₂

d they tend to lose electrons and become cations.

explanation:

coil wire, increase current, put iron inside the coil
