One of the ways the Federal Reserve carries out its responsibilities for conducting monetary policy is by trying to affect the level of key interest rates. In early 2016, Federal Reserve Chair Janet Yellen met with President Barack Obama in the White House. According to an article in the Wall Street Journal, a spokesman for the president stated that open double quotehe 'would not anticipate' that Ms. Yellen would go into detail on the path of interest rates at the meeting . . .close double quote Source: David Harrison, open double quoteBarack Obama, Janet Yellen Discuss Economy, Regulation at White House, close double quote Wall Street Journal, April 11, 2016. Which best describes why the president and Ms. Yellen did not discuss interest rates?A. They did not have enough time.
B. The president does not set interest rates.
C. It is important for the Fed to maintain its independence.
D. The Federal Reserve is not a government organization.

Option C - It is important for the Fed to maintain it's independence.

Explanation:

We will note that Obama met with Janet Yellen in march/april 2016 when he was still president and they discussed about different things like: the near and long-term growth outlook, the state of the labor market, inequality, and potential risks to the economy, both in the United States and globally.

However, they didn't discuss anything on monetary policy and interest rates. This was not because they didn't have enough time because they talked about so many things like i stated above.

It was also not because the president doesn't set interest rates as we all know it's the duty of the federal reserves to do that and also Yellen wasn't meeting obama for him to set interest rates. Also, it couldn't be because the federal reserve isn't a government organization because it is one.

So the only correct option would be that he didn't want to interfere or put pressure on Yellen and the federal reserves because they are meant to be independent.

sound is invisible, but sometimes we can feel it. when a kettle-drum is thumped with a stick that time the tight drum skin moving up and down very quickly for some time and then it pumped sound waves into the air. loudspeakers also work in a similar manner.

components of a speaker:

electromagnet

in order to translate an electrical signal into an audible sound, an electromagnet is used in looudspeakers

  suspension

suspension is used to   center the voice coil in the gap of the magnet and it exerts a restoring force to keep it there. suspension is used to limits the maximum mechanical excursion of the diaphragm and voice coil.

voice coil

voice coil is a coil of wire which is attached to the apex of a loudspeaker cone. it provides the motive force to the cone by the reaction of a magnetic field to the current passing through it.

cone

in a   loudspeaker, a   thin, semi-rigid membrane attached to the voice coil, which moves in a magnetic gap due to which it vibrates   and produced sound. it is known as diaphragm and it can also be called a cone, though not all speaker diaphragms are cone-shaped.

surround

surround is also known as front suspension. surround is used to join the cone to the chassis. together with the suspension it controls the cone excursion, and it is also used to   determine how energy which is   travelling through the cone is absorbed, and how the speaker limits when it reaches the ends of its travel.

dustcap

dustcap is used to protect the voice coil from dust and dirt. it is a part of the cone.

how speaker work

the outer part of the cone is fastened to the outer part of the loudspeaker's circular metal rim. the inner part is fixed to   voice coil that sits just in front of a permanent magnet . when loudspeaker is hooked up to a stereo, electrical signals feed through the speaker cables into the coil. it will convert the coil into an electromagnet magnet . when electricity flows back and forth in the cables, the electromagnet either repels or attract the permanent magnet. this moves the coil back and forth, and it pull and push the loudspeaker cone. like a drum skin vibrating back and forth, the moving cone pumps sounds out into the air.in this way loudspeakers works.
