a) sera la mitad
b) se duplica
c) se mantendra igual

b) se duplica

Explanation:

The disk is moving with constant angular velocity, let's call it .

The linear velocity of a point on the disk is given by

where r is the distance of the point from the axis of rotation.

In this problem, the object is moved at a distance twice as far as the initial point, so

Therefore, the new linear velocity is

So, the velocity has doubled, and the correct answer is

b) se duplica

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.
