Which of Newton's laws of motion states, 'every action force has an equal and opposite reaction force?'

A. Newton's 1st law of motion
B. Newton's 3rd law of motion
C. Newton's universal law of gravitation
D. Newton's 2nd law of motion

Answers

B

newton’s 3rd law of motion states that.
Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object

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 --

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."

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.

What does the amplitude of a light wave determine?
