White objects absorb all wavelengths of light? true or false

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).

Four objects each with charge +2.0×10−7c are located at the corners of a square whose sides are 2.0 m long. part a what quantities can be determined using this information? check all that apply. the electric force on a charged object placed at the center of the square. the mass of each object. the total electric potential energy of the system consisting of the four charged objects. part b find the electric force on a charged object placed at the center of the square.

Aloaded 355 kg toboggan is traveling on smooth horizontal snow at 4.00 m/s when it suddenly comes to a rough region. the region is 6.60 m long and reduces the toboggan's speed by 1.00 m/s . what average friction force did the rough region exert on the toboggan?
