1. 1 - Pick Answer Consider Hooke’s law on a certain material X, that is deforming under a longitudinal stretch. Which of the following principles and effects can be expected if the deformations stay within the elastic limit of material X.

   1. A) The deformation will return to its original shape, the force is proportional to the distance of the deformation.

   2. C) The deformation will return to its original shape, the force is inversely proportional to the distance of the deformation.

   3. B) The deformation will not return to its original shape, the force is proportional to the distance of the deformation.

   4. D) The deformation will not return to its original shape, Hooke’s law does not apply in this situation.

2. 2 - Pick Answer When considering the process of human hearing, from what location of the ear and with what type of signal are the vibrations transmitted from the ear to the brain.

   1. From the basilar membrane located in the cochlea, electric signal

   2. From the eustachian tube, electric signal

   3. From the basilar membrane located in the cochlea, chemical signal

   4. From the helicotrema located in the cochlea, electric signal.

3. 3 - Pick Answer Which statement best describes the First Law of Thermodynamics as it applies to human physiology?

   1. The total amount of energy in the human body remains constant as it is neither created nor destroyed, only transformed from one form to another.

   2. The human body constantly produces energy from food, which is then released as work and heat.

   3. In the human body, energy can only be created or destroyed; it cannot be transformed.

   4. The human body uses special physiological processes to regulate energy, working outside of the limitations of the First Law of Thermodynamics.
