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
Sliding: when an object slides across a surface
rolling: when an object rolls across a surface
static is when something ain't moving
Answer:
The decay constant is 1.21×10^-4/year
Explanation:
Decay constant = 0.693/half-life
Half-life = 5730 years
Decay constant = 0.693/5730 years = 1.21×10^-4/year
Three of these are strong electrolytes:
- HCl (Hydrochloric acid)
- HNO3 (Nitric acid)
- NaOH (Sodium hydroxide)
Two of these are Weak electrolytes:
- HF (Hydrogen fluoride)
- HC2H3O2 (Acetic acid)
And the other two are Non-electrolytes:
- C6H12O6 (Glucose)
- C2H5OH (Ethanol)
The electric force between two charged particles can be increased by decreasing the distance between the two particles.
<h3>How to increase electric force between two charged particles.</h3>
The technique of decreasing the separation distance between objects increases the force of attraction or repulsion between the objects. while
increasing the separation distance between objects decreases the force of attraction or repulsion between the objects.
