Charges of: 2microcoloumb, - 3microcoloumb and 4 microcoloumb are placed in at the vertices of an equilateral triangle of sides 10 cm. what is the magnitude of resultant force acting on 4 microcoloumb charge? the answer is 15.7n. give a logical explanation of the answer

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).
