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.

I need help with question 8 .
Vesnalui [34]

The bike is maintaining "constant velocity".  He's moving at 15 m/s when we see him for the first time, 15 m/s later that day, and 15 m/s next week.

The car starts from zero, and goes 4.0 m/s FASTER each second. After one second, it's going 4.0 m/s. After 2 seconds, it's going 8 m/s. And after 3 seconds, it's going 12 m/s.  

This is the point at which the question wants us to compare them ... 3 seconds.  The bike is moving at 15 m/s and the car has sped up to 12 m/s. <em>The bike is moving faster than the car.</em>

If we hung around and kept watching for another second, the car would then be moving at 16 m/s, and would be moving faster than the bike.  But we lost interest after answering the question, and we left at 3 seconds.

Red light has a _____ wavelength and a _____ frequency than does blue light.

In a spectrum of visible light, we will see that red appears to have a longer wavelength than the blue light. Since wavelength and frequency are inversely proportional then, red will have a smaller frequency than does the blue light.
