Avelodrome is built for use in the olympics. the radius of curvature of the surface is 20.0 m. at what angle should the surface be banked for cyclists moving at 17.5 m/s? (choose an angle so that no frictional force is needed to keep the cyclists in their circular path. large banking angles are used in velodromes.)

Put these events in the correct order #1-4. cause: world war 1 caused heavy casualties and property damage throughout europe. many people barely had enough food to eat or coal to stay warm. what happened next? question 1 options: russia, now led by lenin, became the first communist nation in history. communism soon spread to many small countries near russia, and eventually spread to cuba, china, and vietnam. led by vladimir lenin, a group called the bolshevik party gained the support of the people and overthrew russia’s monarchy, killing czar nicholas ii and his family. russian citizens, who were starving and poor, became angry at the ruling class who held all of the nation’s wealth. (write them in order of which they happened)
