A small metal bead, labeled A, has a charge of 26 nC . It is touched to metal bead B, initially neutral, so that the two beads share the 26 nCcharge, but not necessarily equally. When the two beads are then placed 5.0 cm apart, the force between them is 5.3×10−4 N . Assume that A has a greater charge.
What is the charge qA and qB on the beads?

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?

9.98 kg of r-134a at 300 kpa fills a rigid container whose volume is 14 l. determine the temperature and total enthalpy in the container. the container is now heated until the pressure is 600 kpa. determine the temperature and total enthalpy when the heating is completed. use data from the steam tables.

Which compound is held together by the electrostatic force between two ions? a. co2 b. cci4 c. h2s d. mgf2
