----------------------------------------------------------------------------------------------------------
Here is every answer for analog and digital (in order)
Analog:
Signal Shape: Smooth and continuous
Numerical Values for Signal Measurements: Analog signals represent one continuous variable as the result of another continuous time-based variable. They are capable of outputting continuous information with a theoretically infinite number of possible values.
Amount of Data that can be transmitted: analog circuits can conduct only fairly low-speed data communications. The maximum data rate over an analog facility is 33.6K bps when there are analog loops at either end. With 56K bps modems, only one end of the loop can be analog. The other end of the connection has to be digital.
Energy requirements: light, sound, temperature, position, and pressure
Privacy and security (ability of the signal to be encoded in a secret code): not encrypted
Clarity of Signal: noise affects clarity and quality, noise is amplified, amplified noise causes more random information in the signal, signal bandwidth is low
Digital (in order):
Signal shape: stepping, square, and discrete
Numerical Values for Signal Measurements: digital communication methods transmit a complete measured value, in other words both a numeric value and a unit of measurement
Amount of data that can be transmitted: First of all, it is theoretically possible to transmit digital signals directly. Unfortunately when we use capacitors and inductors (energy storage devices) to match the impedance from the transmitter to the air (low impedance transistor say 5 ohms to 388 ohms (air)) these components introduce a bandwidth limiting match. Since all impulse functions have infinite bandwidth (transmitting a 1 and a zero) the bandwidth of the transceiver must be multi octave in order to have any reasonable efficiency. Systems engineers simplify the problem by introducing direct sequence modulation where a carrier is modulated 0/180 degrees dependent on the data rate.
Energy requirements: voltage, acoustic pressure, and magnetization of a magnetic storage media
Privacy and security: encrypted
Clarity of signal: noise is lower in amplitude, electronics can ignore the noise, quality of signal is maintained, signal is high

A ball with a mass of 500g is lifted onto a shelf which is 1.5m above the ground. Calculate the gravitational potential energy gained by the bal
Answers
Answer:
The answer you asked would be
Explanation:
Gravitational potential energy is the energy stored in an object due to its position above the Earth’s surface.
This is due to the force of gravity acting on an object. Gravitational potential energy is calculated as follows:
Ep = m × g × h so a Gravitational potential energy is the energy stored in an object due to its position above the Earth’s surface. so the answer would be A ball with a mass of 500g is lifted onto a shelf which is 1.5m above the ground. Calculate the gravitational potential energy gained by the ball (g = 9.8 N/kg).
500/1000=0.5
The equation for GPE is:
GPE[J]= m[Kg+metres] x g[N/kg+gravitational field strength] x h[m+height]
g or gravitational field strength is always 10 on earth.
So we know that:
m= 0.5kg
h=1.5m
g=10N/kg
So you would do:
0.5 x 1.5 x 10
Which is:
7.5
And since GPE is measured in joules the answer is 7.5J
How might the world be a different place if scientists did not share their knowledge with others?
Answers
Answer:
if scientists never share information to others, the world would be different if they never shared
Explanation:
The world would have been a place of people who are under developed in thoughts and unaware of science if scientists did not share their knowledge with others.
What is meant by consciousness ?Consciousness can be defined as the state of mind, with which we are able to understand and analyze things.
Here,
People are being able to understand, realize and analyze the things around them, due to the effective coordination of brain and the conscious state of mind.
Knowledge is the basic thing that builds the thinking ability and consciousness of a human being. People are aware of many scientific things in the world due to the scientific temper they have within their mind.
Scientific temper originates from knowledge. We learn new things from the surroundings. For us to learn these things and analyze those things with our scientific temper, we need to learn about the discoveries and theories in the world.
So, the scientists have a major role in making us more of a science enthusiasts, by sharing their knowledge to the world.
Hence,
The world would have been a place of people who are under developed in thoughts and unaware of science if scientists did not share their knowledge with others.

Explanation:
Older rocks are usually found deep into one side of a formation.
Cute drawing btw :3
Based on the geologic column (diagram), the oldest rock would be found in: Layer O.
A geologic column can be defined as a collection of rock layers that are typically grouped based on their relative ages in an ascending order, usually from the youngest layer to the oldest.
In a geologic column, the youngest layer is usually at the top while the oldest layer is at the bottom.
Hence, each lower layer of a rock is older than the rock layers above it.
Based on the geologic column (diagram), the rock layer which is most likely to be the oldest rock is layer O because the youngest rock is at layer L i.e it sits on top (far left).

Please put a written answer. If you can't answer both questions, that's fine
Answers
Answer:
"Evaporation of warm surface water increases the amount of moisture in the colder, drier air flowing immediately above the lake surface. With continued evaporation, water vapor in the cold air condenses to form ice-crystal clouds, which are transported toward shore.
By the time these clouds reach the shoreline, they are filled with snowflakes too large to remain suspended in the air and consequently, they fall along the shoreline as precipitation. The intensity of lake effect snowfall can be enhanced by additional lifting due to the topographical features (hills) along the shoreline. Once the snow begins to melt, the water is either absorbed by the ground and becomes groundwater, or goes returns back to the lake as runoff.
Lake effect snow events can produce tremendous amounts of snow. One such event was the Cleveland, Ohio Veteran's Day Snowstorm from November of 1996, where local storm snowfall totals exceeded 50 inches over two to three days.
A Summary of the Hydrologic Cyclebringing all the pieces together
Animation by: BramerThe hydrologic cycle begins with the evaporation of water from the surface of the ocean. As moist air is lifted, it cools and water vapor condenses to form clouds. Moisture is transportedaround the globe until it returns to the surface as precipitation. Once the water reaches the ground, one of two processes may occur; 1) some of the water may evaporate back into the atmosphere or 2) the water may penetrate the surface and become groundwater. Groundwater either seeps its way to into the oceans, rivers, and streams, or is released back into the atmosphere through transpiration. The balance of water that remains on the earth's surface is runoff, which empties into lakes, rivers and streams and is carried back to the oceans, where the cycle begins again.Lake effect snowfall is good example of the hydrologic cycle at work. Below is a vertical cross-section summarizing the processes of the hydrologic cycle that contribute to the production of lake effect snow. The cycle begins as cold winds (horizontal blue arrows) blow across a large lake, a phenomena that occurs frequently in the late fall and winter months around the Great Lakes."

Why was it hard for the United States to avoid other nations’ problems?

Answers
Answer:
Only a third of Americans are thought to hold passports -- compared to about 50 percent in Australia, more than 60 percent in Canada and some 80 percent in the United Kingdom. "
First of all, in order to travel even 500 miles from home in Europe, you need a passport, or at least you did until the EU got started.
In America, you can travel 500 miles from home for vacation very easily without one. And in Europe, it also doesn't cost an arm and a leg to take an international flight to visit a foreign country. You can hop a train or even drive. The average American faces hours of expensive plane or boat travel in order to go somewhere where a passport is required. I guess if you're made out of money you should have a passport, but millions of Americans don't live the kind of lifestyle where they can afford long-distance travel. (For some reason, this fact is really hard for jet-setting academics to get their minds around.)
For that matter, why would the average American want to go overseas, where they'll just be derided as a tourist? Sure, I would love to visit darkest Burma and hang out with some hill tribes, but pretty much the best that the average American can hope for, with the small amount of vacation time and money that they have for these things, is to not even get to Burma, and spend a weekend in Patpong.
Secondly...
"When they get wherever they are going, it is crucial that they live and study not just with other Americans, but also with local people of their own generation."
So basically they can go to Florence or London and party with other similarly entitled kids? You forgot "local people of a class other than their own."
