The head of a giraffe is 2.0 m above its heart and the density of the blood is 1.05 103 kg/m3. what is the difference in pressure between the giraffe's heart and head? (fortunately, a giraffe's neck has a special circulatory system to adapt to this neck length, producing an even flow of blood to the head.)

The difference in pressure between the giraffe's heart and head is :

Given that the head of the giraffe head is placed at a higher position the blood pressure in the head will be higher than the blood pressure in the heart. and

Pressure in the Giraffe is directly related to ; density , gravity and height of the giraffe

Therefore pressure = ρ*g*h

                                 = 1.05 * 10³ * 9.8 * 2

                                 = 20580 pa  = 20.58 kPa

Hence we can conclude that the difference in pressure between the giraffe's heart and head is 20.58 kPa.

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
