Mamenchisaurus, a sauropod dinosaur from Sichuan province in the Late Jurassic period, has one of the longest recorded necks of any species on Earth, ranging from 9 – 14 metres in length. Early reconstructions of sauropods placed them underwater like hippopotamus, with their heads protruding from the water like long breathing tubes or snorkels. Assuming that the dinosaur is underwater in a lake or other body of fresh water, as shown in the image; and the distance from the dinosaur's nose to its lungs is 13.7 metres, determine the (outside) pressure on the lungs. (Units: Pa). For the dinosaur to be able to breathe in (draw air into its lungs), its body must have had the capacity to reduce this pressure on the lungs, to the point where the pressure inside was less than the pressure at the dinosaur's nose

An ocean dwelling dinosaur has an estimated body volume of 1.38 x 10^6 cm^3 and a mass of 1.24 x 10^6 g. What is its density?
Suppose that the weight of a type of organism is governed by a power law relationship with its length from snout to tail and the thickness of its central vertebrae W=cL^pV^q. One specimen weighed 37 kg with a length of 1.6 meters and vertebral thickness 1 cm. A second specimen weighed 45 kg with a length of 1.6 meters and vertebral thickness 1.3 cm. A third specimen weighed 56 kg, with a length of 3.1 meters and vertebral thickness 1.2 cm. Write the equation with the correct coefficient and parameter values. (Express values to the nearest hundredth).
