2 or dioxygen. Ozone is formed from dioxygen by the action of ultraviolet light and also atmospheric electrical discharges, and is present in low concentrations throughout the Earth's atmosphere (stratosphere). In total, ozone makes up only 6993600000000000000â 0.6 ppm of the atmosphere.
Of the many car driving tips that might be offered, this one isn't intuitive-accelerate through curves to gain better traction. It seems that acceleration on a curve would cause a vehicle to loose traction and fishtail. It does if you apply too much, but limited acceleration improves traction when taking a curve.
Altair's flattened ellipsoid shape has been directly imaged (more). Altair has one of the fastest known rotational speeds -- 210 kilometers per second (131 miles per second)-- and so completes at least one rotation in about 10.4 hours.
