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.
<h3>
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.

Answer:
The correct answer is B)
Explanation:
Self-direction is a learning method used to help students understand as they are instructed and give themselves a direction that they ultimately obey. It is, in other of words, the mechanism of self-regulation, or self-command.
It may be useful for students who are hyperactive, and who may have direct instruction issues as well as people who elicit unique strong emotions, too
Also, students with learning disabilities will find self-instruction very useful.
An example of self-instruction is strategy is the W-S-T-C. This means
- What are you going to do about the situation/problem?
- Select a strategy for the task you'd like to perform
- Try the strategy
- Check and evaluate if the strategy works

Answer: The choice of a submarine to either sink or float depends on the captain of that submarine. For a submarine to sink the captain just have to allow water to fill the water tank (lock), making the submarine more dense than the water it has displaced. For it to float, it just have to empty the water tank and allow air to fill it.
When a boat in a canal lock sank, the water level will rise, because the volume of the boat has displaced more water, and this displaced water will cause the water level to rise. The space occupied by an object in a water, is equal to the volume of water been displaced.
Answer:
