Answer:
Explanation:
The capacitance of a parallel-plate capacitor is given by the formula:
where k is the dielectric constant of the material between them, A the area of the plates, d the distance between them and the permittivity, an universal constant.
Since the area of the plates is the product of their sides a=4.3cm=0.043m and b=4.2cm=0.042m, in S.I. we have:
Answer:
3.) scientific field that uses technology to purposefully change living things
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments. One of the most important branch of science is bioengineering. Biotechnology can be defined as a high-tech process which avail scientists the opportunity or ability to modify, remove, replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
For example, selective breeding also referred to as artificial selection is being used to create plants that are more resistant to certain biological diseases. Thus, this is an example of an organism being changed through technological methods commonly known as biotechnology.
Hence, the phrase which best defines biotechnology is that, it is the scientific field that uses technology to purposefully change living things.
B.
The original energy is mgh. The final energy is 1/2 mv^2.
The energy that is not converted to kinetic energy is the work done against resistive forces, which is mgh - 1/2 mv^2.
Answer:
"its varying position means that the Sun lights up different regions, creating the illusion that the Moon is changing shape over time. The best way of getting to understand the lunar phases is to regularly go out on a clear night when the Moon is in the sky and observe it."
I believe the formula you're looking for is force equals mass times acceleration. in this case the answer would be 3.
