A localized source (such as an antenna, for example) is radiating electromagnetic waves outward in all directions. Far away from the source, at 8.5 km away, the intensity of the EM wave is measured to be 43 μW/m2. What is the peak value of the magnetic field of that EM wave at that location? (in T)

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).

What are atoms of the same element with different numbers of neutrons called?

What is nasa currently considering as possible ways to decrease the impact of radiation during longer space missions?
