A gas is enclosed in a container fitted with a piston of cross section average 0.1 meter per square. The pressure of gas is maintained at 800 newton into meter per square. When heat is slowly transferred .The piston is pushed up through a distance of 4cm if 42 j is heat is transferred to the system during the expansion what is the expansion what is the change internal energy of the system

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?
