Answer: Liquefaction occurs when the structure of a loose, saturated sand breaks down due to some rapidly applied loading.
As the structure breaks down, the loosely-packed individual soil particles attempt to move into a denser configuration. Liquefaction most often occurs when three conditions are met:
loose, granular sediment or fill
saturation by groundwater
strong shaking
Answer:
When the pressure surrounding a substance increases, the freezing point and other special points also go up. It is easier to keep things solid when they are under greater pressure. Generally, solids are more dense than liquids because their molecules are closer together.

Answer:
a) ΔV = 20 V
, b) Q = 35.4 10⁻⁹ C, c) C = 1.77 10⁻⁹ F
Explanation:
a) The electric potential is
ΔV = E x
ΔV = 4.0 10⁵ 50 10⁻⁶
ΔV = 20 V
c) The capacity of a capacitor is
C = ε₀ A / d
The area of a square plate is
A = L²
A = 0.10²
A = 0.01 m²
L = 50mm = 50 10⁻⁶ m
Let's calculate
C = 8.85 10⁻¹² 0.01 /50 10⁻⁶
C = 1.77 10⁻⁹ F
b) the charge is
Q = C ΔV
Q = 1.77 10⁻⁹ 20
Q = 35.4 10⁻⁹ C

Answer:the hare slept for 1 hr 55minutes.
Explanation: distance is changed to meters = 520m
Speed=distance/time
Speed of tortoise is 0.075m/s=520m/t
Crops multiplying t= 520/0.075 = 6933.3 seconds.
Speed for hare 16.7m/s =260m/t
ie 260m is half of the distance.
t =15.56seconds
Therefore the time slept by the hare = 6933.3- 15.56= 6917.74 seconds.
Converting to hours = 1hr. 55minutes is the time the hare slept.
