HOW ARE SOUND AND LIGHT WAVES ALIKE AND DIFFERENT?


short answer please

Answers

Answer:

Light waves are electromagnetic waves while sound waves are mechanical waves.

sound waves cant travel in vaccums while light wave can, hence why ppl say u can scream in space and ppl wont hear u.

Answer: Sound and light are similar in that they both move in waves and are sources of energy. They have wavelength, frequency, and amplitude properties in common. Light can only travel through empty space, while sound can only travel through a medium (substance). Sound is a type of mechanical energy produced by matter vibrations.

The three basic economic questions societies face are (1) what goods and services to produce, (2) how to produce those goods and services, and (3) who will get them.

In one or two paragraphs, explain how supply and demand help societies determine their answers to these three questions. Be sure to provide an example of the effect of supply and demand on a society's answers.

please help

Answers

When supply is high is the people don’t want it as much. When the supply is low people most likely want It. Demand is just basically controlled by the people.

Supply and demand let's us know what needs to be more produced and what needs to be less produced. For example, the demand for a TV will be high, but the demand for paper might be low. So the company will produce more TVs and less paper because the Supply and demand tells them that the people want TVs. When supply is high the people don’t want it as much but the supply is low people most likely want It. Demand is just basically controlled by the people.

What is the flaw with using apparent brightness rather than absolute brightness to determine the brightness of a star?

Apparent brightness does not use the star's color or temperature.

Apparent brightness does not take into account the distance of the star from Earth

Apparent brightness is only theoretical, its value cannot be directly measured with equipment

Apparent brightness is only on a comparative scale that determines how bright a star looks from a theoretical distance of 10 parsecs
from Earth.

Don’t answer if you’re just going to put a link or file.

A tree outside Daves house is 12 feet tall Which of the following statements is CORRECT?a. Suppose you are managing a stock portfolio, and you have information that leads you to believe the stock market is likely to be very strong in the immediate future. That is, you are convinced that the market is about to rise sharply. You should sell your high-beta stocks and buy low-beta stocks in order to take advantage of the expected market move.b. Collections Inc. is in the business of collecting past-due accounts for other companies, i.e., it is a collection agency. Collections' revenues, profits, and stock price tend to rise during recessions. This suggests that Collections Inc.'s beta should be quite high, say 2.0, because it does so much better than most other companies when the economy is weak.c. Suppose the returns on two stocks are negatively correlated. One has a beta of 1.2 as determined in a regression analysis using data for the last 5 years, while the other has a beta of %u22120.6. The returns on the stock with the negative beta must have been negatively correlated with returns on most other stocks during that 5-year period.d. If the market risk premium remains constant, but the risk-free rate declines, then the required returns on low-beta stocks will rise while those on high-beta stocks will decline.e. You think that investor sentiment is about to change, and investors are about to become more risk averse.
