<u>Answer:</u>
Option: D. Gravity is pulling the crash test dummy in the direction the car is moving.
<u>Explanation:
</u>
When a car accelerates from a standing start, the crash test dummy appears to be pressed backward into the seat cushion because the gravity is pulling the crash test dummy in the direction the car is moving.
Basically when the car is starting, the person inside is in static position and the car is going to move. So it is putting a force on the person to move on the same speed. But as the person is sitting static hence gravity is pulling him behind from moving. Hence, The dummy appears to be pressed backward.
A neutral object contains no net charge, but still has many charged particles within the object, it just means that the charges cancel each other out.
Refraction is simply the bending of light when it moves from one material into another. If light is beamed at 90° to a surface, no bending happens. But if you shine the light at an angle it will bend one way or another.
Diffraction is a process in which a beam of light travels through a gap or around a barrier, and spreads out as a result.
<span> Dispersion is the property that the speed of light in a transparent material is different for different wavelengths. Thus the index of refraction is likewise different.</span>
A confined aquifer is a permeable rock unit found deep underground. It is usually overlain by another relatively impermeable rock or clay. This rock or clay layer limits the movement of the underground water whether into or out of the aquifer.
Since water is a liquid, therefore, is is always seeking a way out to leak.
Based on this, when a confined aquifer intersects with a fracture or a well, the water inside the aquifer will tend to move laterally until it can find a spot to leak from.
Therefore, the answer is "<span>It will move laterally until it finds a way out"</span>
Answer:
Sinkhole fatalities are rare, but they do occur sometimes. Also fatalities are more likely where sinkholes are common. For example, sinkholes are more common in Florida than in California, so you would more likely die from a sinkhole in Florida than you would in California.
Hope this helps!
