this type of wave is reflected by particles in the ionoshphere

Answers

Answer 1

The ions in the ionosphere reflect radio waves.

A large percentage of the free electrons in the ionosphere affect radio propagation. The ionosphere's free electrons oscillate in response to high-frequency (HF) radio waves, which causes them to radiate energy back down at the same frequency. This effectively bounces the radio wave back towards the Earth.

Only electromagnetic waves with extremely high frequencies and visible light can travel through the ionosphere. As a result, only radio waves and visible light can pass through the ionosphere without being reflected.

Because it receives energy from the Sun, the ionosphere, a very active component of the atmosphere, expands and contracts. The gases in these layers are energized by solar radiation to generate ions, which have an electrical charge, hence the name ionosphere.

Based on lessons from history, the enslaved Blacks were often loyalists or neutral.

Which side did Blacks choose in the American Revolution?

Enslaved Black people in the Americas would often be loyalists because the British had promised that the enslaved Blacks who supported them would be freed when the British won.

Often however, the enslaved Blacks were neutral because they did not want to be caught in the violence and did not want to support either side because they were both White enslavers.

In conclusion, Enslaved Blacks were loyalists and neutral.

At the beginning of the movie how would you describe the school and joe Clark’s class in the movie lean on me

Answers

In Paterson, New Jersey, Eastside High School's principal was Joe Louis Clark. Lean on Me, a 1989 movie starring Morgan Freeman, is also about him.

How would you characterize the school and Joe Clark's class at the start of the film Lean on Me?

Joe Clark's presence was primarily intended to address the issue of the children' reading proficiency, as their scores were 42% below the necessary level. This was learned from the outcomes of the practice exam the pupils took.

Peer studying and remedial classes are only two of the new approaches that have been used to combat this issue. The usage of this theme was very beneficial since it highlighted ways in which school administrators can raise the academic performance of their students. Dictatorship was another issue that was presented.

What school served as the inspiration for Lean on Me?

It is based on the true story of Joe Louis Clark, a Paterson, New Jersey, inner city high school principal whose institution faces state government receivership unless students receive higher results on the New Jersey Minimum Basic Skills Test.

What did you discover after seeing Lean on Me?

He was aware that in order to respect others, one must first respect oneself. If there is a lesson or moral to this story, it is that young people need to know that someone cares about them and that, given the right environment and opportunities, they will succeed most of the time.
