No, ringworm does not always have to appear in a circular shape. It can present in various shapes and sizes on the skin.
The direction of the object's velocity is always changing as it moves in a circular path.
No, ringworm is not always circular in shape. It can appear as a red, scaly patch on the skin that may be round or irregular in shape.
The centripetal force is always perpendicular to the motion in circular motion. It acts towards the center of the circle, keeping the object moving in a circular path.
The direction of its velocity is always changing.
A gasket may or may not be circular, and it is usually flat on both sides. An O ring is always circular, and circular in girth as well.
The Centripetal Force
Yes, centripetal acceleration is the acceleration that keeps an object moving in a circular path. It is always directed towards the center of the circle and is necessary to maintain circular motion.
Due to Uniform Circular Motion.
Electricity can kill by disrupting the electrical signals in the body, especially the heart, leading to cardiac arrest. High-voltage electricity can cause severe burns and internal injuries. It is important to always handle electrical equipment and wires with caution to prevent accidental electrocution.

No, the distance between the sun and the earth varies continuously because the earth's orbit is elliptical not circular. Also the position of the sun changes in response to the gravitational pull of the planets orbiting it (especially massive Jupiter).
