Answer:
![n_l=1.58](https://tex.z-dn.net/?f=n_l%3D1.58)
Explanation:
Newton's ring equation relates the initial and final diameter of the ring, to the index of refraction of the air and the index of refraction of the liquid between the lens and the plates, as follows:
![n_ld_f^2=n_ad_i^2](https://tex.z-dn.net/?f=n_ld_f%5E2%3Dn_ad_i%5E2)
Solving for :
![n_l=n_a\frac{d_i^2}{d_f^2}\\](https://tex.z-dn.net/?f=n_l%3Dn_a%5Cfrac%7Bd_i%5E2%7D%7Bd_f%5E2%7D%5C%5C)
Recall that the refractive index of the air is 1. So, replacing the given diameters:
![n_l=\frac{(1.52cm)^2}{(1.21cm)^2}\\\\n_l=1.58](https://tex.z-dn.net/?f=n_l%3D%5Cfrac%7B%281.52cm%29%5E2%7D%7B%281.21cm%29%5E2%7D%5C%5C%5C%5Cn_l%3D1.58)
William Harvey wanted to conduct public autopsies si that the general public might learn from them. However, at that time, anatomical studies were considered as taboos and were disproved by the doctrines. Leonardo da Vinci's anatomical drawings were also charged with heresy.
Answer:
741 J/kg°C
Explanation:
Given that
Initial temperature of glass, T(g) = 72° C
Specific heat capacity of glass, c(g) = 840 J/kg°C
Temperature of liquid, T(l)= 40° C
Final temperature, T(2) = 57° C
Specific heat capacity of the liquid, c(l) = ?
Using the relation
Heat gained by the liquid = Heat lost by the glass
m(l).C(l).ΔT(l) = m(g).C(g).ΔT(g)
Since their mass are the same, then
C(l)ΔT(l) = C(g)ΔT(g)
C(l) = C(g)ΔT(g) / ΔT(l)
C(l) = 840 * (72 - 57) / (57 - 40)
C(l) = 12600 / 17
C(l) = 741 J/kg°C
