Imperfections in the electrodes and poor mechanical contact with the conducting paper can affect the electric fields that are measured in this experiment. What type of error does this introduce into your calculations

Which one of the following research methods can show cause and effect

What is the equation for electrical work?

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?
