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.
Answer:
Explanation:
Let the total force be F
The force that produces motion in the x direction is given as, 
Let the frictional force be given as:
Thus, the net force is given as:
Answer:
Polished surfaces reduce heat loss
