Why was it hard for the United States to avoid other nations’ problems?
due by 11:59pm helppp :''(
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."

Climate models are computer simulations of all the complex interactions of the atmosphere, oceans, land surface, ice and biosphere. They account for the incoming radiation from the sun and the radiation emitted back out to space. To be able to provide reliable climate simulations and predictions, climate models must be based on the laws of physics and chemistry --

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
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).

How does the angle of light affect the electrical output from a solar cell?
Answer: A photovoltaic solar panel produces electricity in direct proportion to the amount of sunlight falling on it.
Explanation:
The sun's angle in the sky influences the intensity of the light received by the Earth, the location of the sun affects how much energy a solar panel generates.
Answer:
A name as photovoltaic solar panel produces electricity in directions proportion to amount of the sunlight falling it.
Explanation:
the sun's angle in the sky influences the light received by the Earth.
What are three ways that waves are measured, and which of these
measurements is associated with the energy and strength of a wave?
Crest - The highest point on the wave above the still-water line. Trough - The lowest point on the wave below the still-water line. Wave Height - The vertical distance between crest and trough. Wavelength - The horizontal distance between successive crests or troughs.
Scientists use the terms amplitude, wavelength, and frequency to refer to some commonly measured properties of waves.

Does the number of particles change as the substance changes its state?
Answer:
no
Explanation:
No, the number of particles does not change as the substance changes its state. Change of state from one phase to another is achieved by providing or absorbing heat or pressure. For instance, liquid water if heated becomes vapour steam and if cooled becomes solid ice.

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?
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.
