SP6 – A thin uniform rod is bent in the shape of a semicircle of radius R. Where is the center of mass?

Centroid of a semi circle is the center of the mass.

Explanation:

Centroid is the point exactly at the center of the circle. If the rod is bent to form semi circle shape then its center of mass will be exactly at the centroid. The mass of the rod should be uniformly distributed. The rod shape should be symmetrical forming the semi circle.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
