If any problems involving circular motion, which way does the tangential speed vector point?

It is always drawn along the tangent of the circle at the point where we need the velocity.

Explanation:

When object is revolving in circular path in either clockwise of counterclockwise direction then in that case the direction of velocity is always determined by making a tangent at the position on the circle where we wish to find the velocity

Direction of tangent is always by sense of rotation either clockwise or counter clockwise.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
