I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications.
Answer:
The angle of refraction is 37°.
Explanation:
let n1 be the refractive index of glass and n2 = 1.0 be the refraction index of air, θ be the angle of incidence , ∅ be the angle of refraction.
then, according to Snell's law:
n1×sin(∅) = n2×sin(θ)
sin(∅) = n2×sin(θ)/n1
= (1.0)(sin(71°))/(1.56)
= 0.606101651
∅ = 37°
Therefore, the angle of refraction is 37°.
Answer:
The temperature of well water be 288.07 K
Explanation:
We have given Heat in house 
Work done W = 900 J
Efficiency is given by 
Efficiency is also given by 
, here 
is lower temperature and 
is higher temperature
So 
So the temperature of well water be 288.07 K
I believe it's 'A'. Hopefully this helps!~ :)
