Answer:
T=502.5N
Ax=171.8N
Explanation:
The computation of the tension T in the rope and the forces exerted by the pin at A is shown below:
vertical forces sum = Ay + Tsin20 + T - 245 - 883 = 0
Now
horizontal forces sum = Ax - Tcos70
Now Moment about B
-Ay × 4.8 + 245 × 2.4 + 883 × 1.8=0
Ay=453.6N
Now substitute in sum of vertical forces T=502.5N
Ax=171.8N
Chemical stimuli are molecules that cause a response at a cellular level primarily through cellular receptors. This happens all the time in nature - cells communicate with one another through chemical messaging. An example is an aroma molecule, such as the scent from a flower. This particular molecule is detected by the olfactory cells (those associated with the sense of smell) in your nose, producing a chemical reaction that ultimately leads to you consciously experiencing the smell.
Answer:
<em>#1:</em><em> Most likely it does so, and calls other paramedics to help the person it was on its way to go help. But usually people will stay out of its way when they hear one coming...</em>
<em>#2:</em><em> Probably, because they usually just don't want meat, and don't have problems with things such as crackers. I doubt that they can live solely from vegetables!! It seems impossible!!</em>

I have to say they are some quite interesting questions. Interesting to think over... :) Anyway, I hope my answers help answer yours!!
Answer:
Thin, aluminium and buried underground.
Explanation:
When it comes to electrification of a state or province, some characteristics of the wire to use must be considered. This would help to minimize and avoid power loss and wire burns.
i. The wire to use should be thin, and a quite number can be twisted one against the other so as to increase the surface area for heat dissipation.
ii. Aluminium wire is more preferable for this project. It has a high melting point, and reduces energy loss.
iii. Burying the wire underground through an insulator is the best choice, though expensive but would preserve the wire from external influence.
