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.

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."

(I put these in quotes to give credit to the person who already answered this a long while ago in a different question).

Ocean water gains heat from the sun and evaporate into water vapour. The water vapour then rises and form clouds, it then loses heat and condenses to form water droplet(rain), which then drips back into the ocean and the whole cycle repeats

When there is more speed does that mean there is more or less force?
When there is less speed does that mean there is more or less force?
When there is more mass does that mean there is more or less force?
When there is less mass does that mean there is more or less force?

Answers

Answer:

1. The answer is that there will be more force with more speed.

2. less speed means less force.

3. And last, but certainly not the least, the less the mass has, the less the force will be, unless the object is moving at a high speed.

Explanation:

If a heavy (more massive) object is in motion, more force must be applied to get the object moving faster. If the same force is applied to two objects, the object with the smaller mass will change speeds more quickly.

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




due by 11:59pm helppp :''(

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."

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).

First you would need to convert grams to 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
