If wire XY of resistance = 2 ohms is replaced by another wire AB of the same material. Wire AB has double the cross-section area and half the length of that of XY. Calculate the resistance of wire AB

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).

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