If a SIGWX chart shows a wind speed of 10kts, which symbol would you expect to see?

Explanation:
Wind barbs on SIGWX charts encode wind speed and direction. The markings on the barb indicate speed: a short bar equals 5 knots, a longer feather equals 10 knots, and a pennant equals 50 knots. So for a wind speed of 10 knots, you’d see one feather on the barb. The pennant would indicate a much higher speed (50 knots), circles aren’t used to convey this wind-speed value on these charts, and a simple bar without the feather wouldn’t properly convey 10 knots.
