Electromagnetic waves can carry more data at higher frequencies. Why would a scientist opt to transmit data at a lower frequency instead?

Answers

Answer 1

Answer:Transmitting data over low frequency electromagnetic waves can reach great distances before attenuation because are not easily interfered with by obstacles like high frequency waves are. This is because they can diffract over obstacles and pass around them with less shadowing.

A disadvantage of using electromagnetic waves to transmit data is interference. One cause of interference is the transmission ton over same frequency hence the necessity to regulate these waves through policies. Other causes of interference are due to weather or obstacles.

Analogue signal is the decoding of electromagnetic waves into electric pulses (of varying amplitudes) by a decoder and pass the electric circuit in the electronics. However, in digital signal, electromagnetic waves are converted to binary format (0s and 1s). Therefore, analogue signal is a continous signal while digital is discretely broken down into bits.

Digital signal have the advantage of analogue signal over the fact that they can carry loads of information. Analogue signal draws more power than digital signal hence the later is eco-friendly. Digital signals are less likely to be affected by noise unlike analogue signals.

One major application for analogue signals is their use is speakers and microphones. Nonetheless, contemporarily, there are emerging digital microphones and speakers. A popular example of application of digital signal is in the mobile communication industry. The shift from analogue to digital has been greatly revolutionalized communication

How do nozzles aerosolize liquids?

Answers

Answer:do you mean noddles

Explanation:not sure how to answer this.

Hello!

Answer:
Nozzles aerosolize liquids by breaking them up into small droplets or particles this process involves several steps:

1.pressure: liquids are often pressurized before being sprayed through a nozzle. This pressure helps to overcome the liquid surface tension and forces it through the nozzle opening.

2.constriction: the nozzle has a small opening, which constrains the flow of liquid as pressurized liquids passes through the narrow opening, the flow rate increases, and the liquid gains Momentum.

3.shear forces: as a liquid flows through the nozzle and experiences shear forces, these forces cause the liquid break apart into smaller droplets or particles. The size of the droplets produced depends on factors such as the liquids viscosity and the nozzle’s design.

4.Atomization: the shear forces generated by the nozzle result in the atomization of the liquid that means that the liquid is broken down into tiny, droplets or particles creating a aerosol. These droplets or particles are smart enough to remain suspended air.

5.spray pattern: the shape and size of the nozzle opening determine the spray pattern, different nozzle, designs produce different spray patterns, such as a wide cone, narrow cone, or flat fan. The spray pattern affects the distribution and coverage of the aerosolize liquid.

Sheldon Adelson’s financial contributions to both Newt Gingrich’s political campaign and Donald Trump’s political campaign is an example of the proletariat trying to manage the laws that govern the economy.

Answers

Sheldon Adelson’s financial contributions to both Newt Gingrich’s and Donald Trump’s political campaign is given below.

Explanation:

1.Sheldon Adelson is the chairman and CEO of the Las Vegas Sands Corporation. He has contributed to numerous Republican campaigns and organizations. He supported Newt Gingrich and Mitt Romney in the 2012 presidential campaign and Donald Trump in the 2016 campaign.

2. Adelson donated to American Solutions for Winning the Future, a political action committee connected with Newt Gingrich, and supported Gingrich's presidential campaign in 2012.He donated to Mitt Romney’s presidential campaign after Gingrich dropped out of the race.

3. Casino mogul Sheldon Adelson has given $5 million to an independent committee supporting GOP presidential aspirant Newt Gingrich, the first of what is expected to be many millions the Las Vegas billionaire plans to spend this election year. The check from Adelson is the latest in an avalanche of campaign cash flooding the presidential season to independent groups known as Super PACs The check was cut on Friday to Winning Our Future, a group run by former Gingrich associates, according to two people close to the donor.

4. He sat out the Republican primary season during the 2016 presidential campaign but on September 23, he announced a $25 million donation to Donald Trump's 2016 presidential campaign, making him the largest donor to the Trump campaign and the largest donor in the presidential election.

5. The billionaire casino owner Sheldon Adelson, an ardent pro-Israel conservative, is expected to donate at least $100m to boost Donald Trump’s 2020 re-election efforts and Republican congressional candidates this fall, say three Republican fundraisers familiar with Adelson’s initial plans.

The greater the force applied to an object, the _____ the change in speed or direction of the object.
A) equal
B) greater
C) lesser
D) slower

Answers

The answer will be greater which is b because how great the force is applied to the object.

Option.B-Greater is the correct answer.

The more force exerted to an object, the more the object's speed or direction will change.

What is Newton second law of motion?An object accelerates whenever it increases its speed, decreases its speed, or changes direction.When an unbalanced force acts on an item, acceleration happens. The mass of the object and the net force acting on it both have an impact on an object's acceleration.The influence of force and mass on acceleration is described by "Newton's second law of motion."According to the law, an object's acceleration is equal to its mass divided by the net force acting on it.The second law of Newton demonstrates that force and acceleration are directly related.An object of a given mass will accelerate more quickly the more force is applied to it. For instance, when the force acting on an item is doubled, so is the acceleration.Mass and acceleration have a different relationship. An inverse relationship exists.When one variable rises in an inverted connection, the other variable falls.The less an object accelerates when a certain force is applied, the more mass it has. For instance, when an object's mass is doubled, the acceleration is reduced by half for a given force.
