Answer:
θ1 = 33.38°
Explanation:
From Snell's law of refraction,
n1•sinθ1 = n2•sinθ2
We are given ;
Angle of refraction; θ2 = (90 - 26.4°) = 63.6°
Index of refraction; n1 = 1.628
Index of refraction in air; n2 will have a constant value of 1
Now, we are looking for angle of incidence θ1, so let's make θ1 the subject;
n1•sinθ1 = n2•sinθ2
So, sinθ1 = (n2•sinθ2)/n1
Plugging in the relevant values;
sinθ1 = (1 x sin 63.6)/1.628
sinθ1 = 0.5502
θ1 = sin^(-1)0.5502
θ1 = 33.38°
There relationship can be the same in a way because both of those slopes can increase
Answer:
Fission is the release of atomic energy related to the splitting of nuclei.
M = M1 + M2 + E where E = m c^2 energy from conversion of mass
if the daughter nuclei are less in total mass than the parent nucleus then the difference is released as atomic energy where E = m c^2 and m is the mass that has been lost in the conversion.
A 1Msun star in a closed binary system with a 2Msun star.
Systems in which the two stars are close to each other are called close binary star system.
The most massive stars have the shortest lifespans. The reason is that they have most fuel, they burn it so enormously that their lifetimes are very short. As a 1Msun star in a closed binary system with a 2Msun star becomes the massive star so it has the shortest life expectancy.
a. No, an isolated 1Msun star has not the shortest life expectancy.
b. No, a 1Msun star in a closed binary system with a 0.8Msun star has not the shortest life expectancy.
c. Yes, A 1Msun star in a closed binary system with a 2Msun star has the shortest life expectancy.
