A 0.5 -m-diameter hollow plastic sphere containing pollution test equipment is being dragged through the Hudson River in New York by a diver riding an underwater jet device. The sphere with an effective specific gravity of \(\mathrm{SG}=0.30\) is fully submerged, and it is tethered to the diver by a thin \(1.5-\mathrm{m}-\) long wire. What is the angle the wire makes with the horizontal if the velocity of the diver and sphere relative to the water is \(5 \mathrm{~m} / \mathrm{s}\) ? The water is at \(10^{\circ} \mathrm{C}\).
