Aperson with a near point of 120 cmbut excellent distant vision, normally wears corrective glasses. but he loses them while traveling. fortunately, he has his old pair as a spare. a) if the lenses of the old pair have a power of +2.60 diopters , what is his near point (measured from his eye) when he is wearing the old glasses if they rest 2.00 cm in front of his eyes? front of his eye? b) what would his near point be if his old glasses were contact lenses instead?

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).
