The difference between the highest and lowest frequencies in a band or collection of frequencies is known as the bandwidth. The bandwidth in a standard North American telephone circuit is 64 Kbps. The amplitude or height of the wave is altered by amplitude modulation.

What do you mean by Telephone Circuits?</h3>
The standard line found in telephone circuits is this one. The frequency response of such a line resembles that of a low-pass RC filter. The telephone line loss and consequently the low-pass filter action increase in frequency as a result of the wires' increasing resistance, which causes an increase in I2R wire losses. 14 The frequency response of a 1 km-long, twisted line is reduced by 9 dB at 1 MHz and keeps going down for higher frequencies, Let's suppose that a straightforward, 1 km-long transmission system is required. A pair of 1 km long twisted copper wires may transmit data with a loss of less than 9 dB.

The correct answer is "provide for the common defence."
According to the Preamble of the U.S Constitution, the aforementioned part about providing for the common defence actually means that the nation should be well prepared against foreign interventions of any kind.
This kind of preparation does not only refer to military preparation but also refers to protecting the country at any costs from external forces.

Answer:Philanthropic and ethical responsibilities
Explanation:
What is ethical responsibility?
She will need to practice fairness as she start her business in such that whatever she does is fair to the people around her and especially to her competitors .
When people are in the business they may even be manipulative liers in order for their business to succeed , they may even set schemes that will see the other similar business going down and losing their businesses.
She will need to be fair ,use her own unique trademarks and strategies to win customers without jeopardising the other similar businesses ability to win theirs.
She may need to outsmart them by just being unique .
What is philanthropic responsibility?
Our carbon footprint plays a huge role in how we protect or demolish the environment, so she will need to find ways to avoid environmental impact that may be caused by her business .
For example selling food using containers that are non biodegradable can impact the environment .
She may also choose packaging bags that are environmental friendly .
Cover the ground around where she works with grass rather than leaving it bare.
The third answer/C seems to be the most accurate, as a good economy would ideally have a balance between needs and ideals.
