Answer:
World languages__
Explanation:
A selective college usually requires more years of ___World languages__ than a high school requires. College graduates would look for jobs after college, they might have to travel to different countries. So, educating them about different language would give them a competitive edge to them. Moreover, in the age of globally integrated business community, knowing an extra language could work as cherry top on the cake.
Complete question is;
When you ride a bicycle, in what direction is the angular velocity of the wheels? A) to your left B) to your right C) forwards D) backwards
Answer:
Option A - to your left
Explanation:
While an object rotates, each particle will have a different velocity:
the 'Speed' component will vary with radius while the 'Direction' component will vary with angle.
All of the velocity vectors are aligned in the same plane.
We can be solve this by choosing a single vector normal to ALL of the possible velocity vectors of the rotating object in that plane.
This convention used is known as "Right-hand rule". The angular velocity vector points along the wheel's axle. For instance, if you Imagine wrapping your right hand around the axle so that your fingers point in the direction of rotation, with your thumb sticking out. You will notice that your thumb points to the left.
Thus;
By right-hand rule, a wheel rotating on a forward - moving bicycle has an angular velocity vector pointing to the rider's left.
So, option A is the correct answer
