Answer:
Nanotechnology helps to improve viscous fingering and the nano-particles can transmit through nanopores of sandstone which helps to increase the recovery by decreasing the surface tension between oil and water. The pore spaces are very fine so water molecules cannot penetrate through all of them in order to push the oil. This is why the nano-particles such as iron (Fe) and Silicon (Si) are used with distilled water. These particles can easily move through the interconnected pores and thereby pushes the oil to move out of it. It is a widely accepted concept in Enhanced Oil Recovery (EOR).
It's being estimated that dinosaurs lived on Earth from about 237 million years ago to about 66 million years ago. So answers B and D are definately too "old", while answer A is too "young". I'd pick answer C as it's most probable.
The statements that hold true regarding the undefinable terms in geometry include,
- A point’s location on the coordinate plane is indicated by an ordered pair, (x, y).
- A plane consists of an infinite set of points.
Therefore, the options A and E hold true.
<h3>What is the significance of geometry?</h3>
In the study of geometry, a point, which contains a coordinated plane, is indicated with the help of variables. Geometry also recommends that a plane consists of infinite set of point, and there is no limit on the number of lines that can pass through a point on the plane.
Therefore, the options A and E hold true and state regarding the significance of geometry.
