Answer:
Resistivity Method
Explanation:
A disadvantage of some geophysical techniques based on magnetism is that their use in urban areas may be subject to distortion resulting from power lines and metals in the immediate vicinity. One method that can be used in such areas relies on soil moisture and the ground's resistance to electricity and is known as Resistivity.
It is usually carried out by injecting a small electrical current through the earth and measured a subtle sub-surface change in resistance over a given area.
The appropriate response is Emotion-centered coping. It is a particular system that was produced in the 1980s by the clinicians Susan Folkman and Richard Lazarus, and these methods concentrate on changing one's passionate response to an unpleasant or disquieting circumstance, for example, getting a finding of a terminal disease.

Answer:
F = 2.6 x 10⁻²² N
Explanation:
According to the Coulomb's Law, the force of attraction or repulsion between two charges is directly proportional to the product of the magnitudes of both the charges and inversely proportional to the square of the distance between them. The formula for the force is given as follows:
F = k q₁ q₂/r²
where,
F = Force of Attraction or Repulsion = ?
q₁ = magnitude of first charge = charge on electron = 1.6 x 10⁻¹⁹ C
q₂ = magnitude of second charge = charge on proton = 1.6 x 10⁻¹⁹ C
k = Coulomb's Constant = 9 x 10⁰ N m²/C²
r = distance between the charges = 885 nm = 8.85 x 10⁻⁷ m
Therefore,
F = (9 x 10⁹ N.m²/C²)(1.6 x 10⁻¹⁹ C)(1.6 x 10⁻¹⁹ C)/(8.85 x 10⁻⁷ m)²
<u>F = 2.6 x 10⁻²² N</u>
