Which one of the following lenses is a converging lens? a) convexo-concave lens b) plano-concave lens c) double-convex lens. d) spherical-convex lens

A converging lens (or convex lens) is curved on both sides. This means the light rays coming out of it come together at a point – they converge. Diagram of how a lens works. The point at which the light rays meet is called the focal point.soooD

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.

That would be kinetic energy
