A spherical, underwater instrument pod used to make soundings and to measure conditions in the water has a diameter of \(100 \mathrm{~mm}\) and dissipates \(400 \mathrm{~W}\).

(a) Estimate the surface temperature of the pod when suspended in a bay where the current is \(1 \mathrm{~m} / \mathrm{s}\) and the water temperature is \(15^{\circ} \mathrm{C}\).

(b) Inadvertently, the pod is hauled out of the water and suspended in ambient air without deactivating the power. Estimate the surface temperature of the pod if the air temperature is \(15^{\circ} \mathrm{C}\) and the wind speed is \(3 \mathrm{~m} / \mathrm{s}\).
