The phenomenon that is observed when an incident ray travelling in a slower medium strikes the boundary of a faster medium with an angle greater than the critical angle is known as total internal reflection.
Total internal reflection results in the the ray being reflected within the medium, instead of leaving it after undergoing diffraction. This phenomenon is the working principle of optical fibers.

Energy available for sustaining Eric's muscular and nervous activity can be calculated by,
Energy available= Standard molar entropy×Number of moles×Temperature
We have, standard molar entropy of glucose = 182 J/K mol
Number of moles of glucose = 1.80 mol
Body temperature = 36.9° C = 36.9 + 273.15 = 310.05 K
Substituting the value we get,
Energy available = 182×1.80×310.05 = 100,456.2 J
25m and also 25m because if you divide 100 by 4 you get 25 and divide 50 by 2 you also get 25
Explanation:
M₂ = Fr²/GM₁
M₂ = [(132N)(.243m)²]/[(6.67*10^-11N*m²/kg)(1.175*10^4kg)]
M₂ = (7.79N*m²)/(7.84*10^-7N*m²)
M₂ = 9.94*10^6 kg
