 Question: does hit the floor have a new cast Context: The flags of Romania and Chad are identical aside from the blue strip on the left, which is slightly darker in the Chadian flag. Romania used the flag from 1866, while in that form appeared for the first time in Wallachia, being officially in use in 1848. Chad began to use its present flag in 1960, after it achieved independence from France. At that time, the Chad and Romanian flags were distinguishable by the latter's inclusion of the Coat of Arms of the Socialist Republic of Romania at the Romanian flag's centre. However, in 1989, the coat of arms was removed entirely after the revolution which overthrew Nicolae Ceaușescu.

Several states allow ICE motorbikes to be operated on roadways without registration, tax, or licensing in the same manner as bicycles, providing certain restrictions are observed. Many state jurisdictions use limits on top speed and/or engine displacement to determine if ICE motorized bicycles require registration and licensing--sometimes as mopeds, sometimes as motorcycles. Some states prohibit the use of motorbikes on multi-use recreational paths or high-speed, limited access roadways, while others require additional safety equipment for operation on public roads, such as wearing a helmet. Many United States cities and other local jurisdictions may impose additional restrictions upon ICE motorized bicycles when operated on public streets and roadways.
 Question: is it illegal to put an engine on a bicycle Context: Rotation in mathematics is a concept originating in geometry. Any rotation is a motion of a certain space that preserves at least one point. It can describe, for example, the motion of a rigid body around a fixed point. A rotation is different from other types of motions: translations, which have no fixed points, and (hyperplane) reflections, each of them having an entire (n − 1)-dimensional flat of fixed points in a n-dimensional space. A clockwise rotation is a negative magnitude so a counterclockwise turn has a positive magnitude.
