The purpose of this lab is to determine whether the surface of an area would affect the coefficient of Friction. My classmates and I have learned a lot in this lab and that there could have been some errors in our lab because the strength of how a person pulls it might be a slight different than the normal force. I learned from this lab that the <span>surface area would have no effect on the coefficient of friction. </span>

If a stress of 1.05 × 107 n/m2 is applied to his ligament, how much will it stretch? the young\'s modulus for the acl is 1.10 ×
Ainat [17]

As we know that

Young's\: Modulus = \frac{stress}{strain}

here we know that

Young's Modulus = 1.10 \times 10^8

stress = 1.05 \times 10^7

now by the above formula we will have

1.10 \times 10^8 = \frac{1.05 \times 10^7}{strain}

strain = \frac{1.05 \times 10^7}{1.10 \times 10^8}

strain = 0.095

Unpolarized light shines pon a photocell for one hour. then, two polarizers, whose transmission axies are offset by 60, are plac
LenaWriter [7]

Answer:

  t = 1.10 h

Explanation:

For this exercise we must calculate the intensity that reaches the cell with the polarizers, for this we use Malus's law

          I = I₀ cos² θ

Let's calculate

         I = I₀ cos² 60

         I = I₀ 0.907

This is the intensity that reaches the cell

To find time, use an inverse proportion rule or rule of three, the intensity Io in

        t = I₀ / (0.907 I₀) 1 h

        t = 1.10 h
