The equation for the change in the position of a train (measured in units of length) is given by the following expression: x = ½ at² + bt³ where a and b are constants and t is time (measured in units of time). if (mass), (length), and (time) represent units of mass, length and time respectively then b must have units of:
(a) (length)/(time)
(b) (length)/(time³)
(c) (mass)(length)
(d) (length)/(mass)
(e) (mass2)(time2)
(f) 1/(mass)(time)
(g) 1/(length)(time)
(h) (time)(mass)
(i) (mass)(time2)
(j) 1/(time³)
(k) (time)/(mass)
(l) (length)/(time²)
(mass)(length2)

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).
