Answer:
Soil engineering helps in analyzing the structure and composition of the soil of the proposed construction site, thus helping in deciding whether the soil of the proposed construction site or building is worth exploiting.
Answer:
output=
Explanation:
output =transfer function ×input
here transfer function G=
input = unit impulse
in S domain unit impulse =1
so output =
=

Answer: the reflection loss is 4%
Explanation:
Given that;
n for window glass is 1.5
we know that
Reflection Loss rλ = (nλ - 1)² / (nλ + 1)²
the reflection of loss rλ at normal incidence between two media with different refractive indexes rλ = n'/n, the ratio indices
where n is index of refraction of air ( 1 )
and n' is the refraction of window glass ( 1.5 )
our nλ is 1.5
so we substitute into the equation
rλ =[ (1.5 - 1)² / (1.5 + 1)²] × 100
= [0.25 / 6.25] × 100
= 0.04 × 100
= 4%
Therefore the reflection loss is 4%
