A ruler of length 0.30m is pivoted at its centre. Equal and opposite forces of magnitude 2.0N are applied to the ends of the rul
kow [346]

Answer:

0.3858 Nm

Explanation:

The torque of the couple is the dot product of the force vector and the couple vector from 1 end of the ruler to the center. This equals to the product of their magnitude times the cosine() of the angle made by their direction:

T = \vec{F} \cdot \vec{s} = Fscos(50^0) = 2 * 0.3 * 0.643 = 0.3858 Nm

Describe two homeostasis mechanisms
frosja888 [35]

Answer:

The interpretation including its given subject is listed in the subsection below on explanatory.

Explanation:

Homeostasis should be any mechanism of self-regulation from which an individual seeks to preserve equilibrium when adapting to requirements better suited towards its existence.

<u>Two mechanisms are given below:</u>

  • Blood Pressure: Pressure is regulated by either a homeostatic system through which the blood becomes circulated throughout the individual's body.
  • Body Temperature: The body requires multiple forms of heat regulatory oversight such as:
  1. Endothermic is something a living creature can hold one's own internal body temperature.  
  2. Ectothermic is really where the external atmosphere absorbs temperature.
