A comet is a celestial body consisting mainly of ice, dust and gas in a eccentric orbit around the sun and having a "tail" of matter blown back from it by the solar wind as it approaches the sun.

On the other hand, an asteroid is a naturally occurring solid object made of rocks, which is smaller than a planet and is not a comet, that orbits a star.

What are the possible benefits and drawbacks of today's system of
taxation?

Answers

Disadvantages of Taxation:

Putting in place an income tax system is quite difficult, especially when trying to control the wealthy and companies.Wealthy people benefit from tax evasion and dishonest avoidance because they can afford to pay for expensive tax "help." Warren Buffet, the famed investor, has been quoted as saying that it is unjust that his secretary pays 30% in taxes but Buffet only has to pay 17% on his income.Some contend that an earnings tax, regardless of its level, may cause financial hardship for people in the lower middle class and lower social classes. Any reduction, no matter how minor, can cause households that are barely making ends meet to significantly lower their standard of living.

Advantages of Taxation:

The income tax enables progressive taxing based on your income. In terms of percentage, a person making $15,000 a year will pay less than a person making $150,000 a year. This method of wealth distribution works well.The existing arrangement also provides the government with a reliable source of income.An income tax creates a discrepancy between the value of a person’s work and what they actually receive (disposable income).

Describe the three patterns of communication​

Answers

The three patterns of communication include:

Verbal CommunicationThe most evident kind of communication would appear to be verbal communication. It makes use of spoken language, either in-person or over the phone. Although most encounters need verbal communication, there are other nonverbal indicators that can add to the meaning of the words themselves. A more sophisticated message is conveyed when spoken language is combined with nonverbal communication.

Non-verbal CommunicationThe use of body language might reveal some information about a speaker's word choice. It can reflect sarcasm, complacency, dishonesty, or sincerity. Body language, including the speaker's posture, hand gesture, facial expressions, and even look, is a common way to communicate these things. A untidy speaker with wrinkled clothes and slouching posture, for example, might convey a lack of assurance or knowledge. Visual Communication Signs, maps, and drawings, as well as color and graphic design, are all examples of visual forms of communication. These frequently support verbal communication and aid in proving a point. Visual aids can aid in the presentation of the message by helping the speaker remember key points, providing the audience with something to look at, and more.
