The tensile strength of spider silk is about 1150 MPa, which is 1.15 x 10^9 N/m².
<span>So given that the diameter of the spider silk is 0.15 mm or 1.5 x 10^-4 m. The cross sectional area is approximately: </span>
<span>A = πr² = (3.14)(1.5 x 10^-4 / 2)² = 1.767 x 10^-8 m² </span>
<span>So this means that the amount of force we can apply before the the silk thread is broken is: </span>
<span>F = PA = (1.15 x 10^9)(1.767 x 10^-8) = 20.32 N </span>
<span>F = mg, so m = F/g = (20.32)/(9.81) = 2.07 kg!!! </span>
I think it is R but then again this is still a guess
Question 1
<h3>Answer: 180 degrees</h3>
Reason: The minute and hour hand form a straight line, or straight angle, which is always 180 degrees in measure.
============================================================
Question 2
<h3>Answer: 36</h3>
Reason: Split a pizza into 12 equal slices. Imagine having 3 such pizzas to get 3*12 = 36 slices in total. This leads to the idea that 36*(1/12) = 3.
============================================================
Question 3
<h3>Answer: 360 degrees</h3>
Reason: This is by definition of what it means to do a full rotation.
