Three electromagnetic waves arrive at a point from the same direction. they are polarized parallel to an x axis, and their electric fields at the point are e1 = a sin(ωt) for wave 1, e2 = b sin(ωt + φ2) for wave 2, and e3 = c sin(ωt + φ3) for wave 3. here t is time. the constants are a = 3.0 µv/m, b = 4.0 µv/m, c = 5.0 µv/m, ω = 7.0 × 106 rad/s, φ2 = π/4, and φ3 = π/2. what is the amplitude (in µv/m) of the electric field that results from the interference of the three waves?

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).
