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.

Does the number of particles change as the substance changes its state?

Answers

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.

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 --

What does the amplitude of a light wave determine?

Answers

The amplitude of a wave is a measure of the displacement of the wave from its rest position. The amplitude is also a measure of the strength or intensity of the wave e.g the loudness
Hope this helps :)
The amplitude of a wave tells us about the intensity or brightness of the light relative to other light waves of the same wavelength.

What are three ways that waves are measured, and which of these
measurements is associated with the energy and strength of a wave?

Answers

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.

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."
