Question

The resistance to the motion of electrons through different types of materals is n decreasing order, dry so·most so uderground water, and ron ore. How can this knowledge and the measurement of the charge reaching the detector per unit time help identity what type of material is under Check all that apply.

a. More electrons will reach the detector from iron than from dry soil.
b. The electrons reaching the detector are affected very little by what's under the surface.
c. The detector will get more electric charge if the resistance to flow is less, and resistance is related to the type of material
d. The electrons reaching the detector will carry water with them if water is under the surface

Answer 1

a and d

Step-by-step explanation:

The ground's resistance is influenced by the form of substances under the earth. Other materials like metals have far less resistance and more electrical conductivity. Therefore more electrons will enter the detectors in the earth that has iron. Therefore, choice a and d is are correct.
