Blood pressure in argentinosaurus. if this long-necked, gigantic sauropod had a head height of 23.7 m and a heart height of 7.00 m, (a) what (hydrostatic) gauge pressure in its blood was required at the heart such that the blood pressure at the brain was 93.1 torr (just enough to perfuse the brain with blood)? assume the blood had a density of 1.06 × 103 kg/m3. (b) what was the blood pressure at the feet?

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
