<em>A) We know that the gravitational Weight of a Body is given by,</em>

$F=8mg$

The expression of young's modulus is given by,

$Y=\frac{Fl}{A\Delta l}$

Replacing the value of the force in the equation of young's modulis we have,

$Y = \frac{8mg*l}{A\Delta l}$

Re-arrange the equation for the rate of l, we have,

$\Delta l = \frac{8mgl}{AY}$

Our values here are giving by,

$m=70kg$

$g=9.8m/s^2$

$l=15*10^{-2}m$

$A=110*10^6m^2$

$Y = 1.5*10^{10}N/m^2$

Replacing in the previous equation we have that,

$\Delta l = \frac{8(70)(9.8)(15*10^{-2})}{110*10^6*1.5*{10}}$

$\Delta l = 4.98*10^{-3}m$

We note that Achilles tendon stretch around 5mm

<em>B) The strain is given by the equation,</em>

$\epsilon = \frac{\Delta l}{l}$

The fraction of the tendon's lenght is the ratio of the change in lenght to the streched lenght, that is

$\alpha = \frac{\Delta l}{l}$

$\alpha = \frac{5*10^{-3}}{15*10^{-2}}$

$\alpha = 0.033$

The fraction of the tendon's lenght is 0.0333

What happens to the ray of light when it travels from glass to water?

vodomira [7]

Glass and water are thicker and heavier than air. They are said to be 'denser' than air. What happens is that light slows down when it passes from the less dense air into the denser glass or water. This slowing down of the ray of light also causes the ray of light to change direction.
