Ahorizontal disk rotates about a vertical axis through its center. point p is midway between the center and the rim of the disk, and point q is on the rim. if the disk turns with constant angular velocity, which of the following statements about it are true? (there may be more than one correct choice.)

p and q have the same linear acceleration.
the angular velocity of q is twice as great as the angular velocity of p.
the linear acceleration of p is twice as great as the linear acceleration of q.
the linear acceleration of q is twice as great as the linear acceleration of p.
is moving twice q as fast as p.

The linear acceleration of Q is twice as great as the linear acceleration of P.

Explanation:

As we know that disc is rotating about the vertical axis with constant angular speed

So here we can say that the acceleration of any point on the disc is given as

where we know that

r = radial distance of the point

also for the linear speed of the point on the disc is given as

so we know that

distance of point Q is double the distance of point P

so we will have

the arctic is a region of the planet, north of the arctic circle, and includes the arctic ocean, greenland, baffin island, other smaller northern islands, and the far northern parts of europe, russia (siberia), alaska and canada.
