A sound wave travels through water at 1,500 m/s. How far would it travel in 5 s?

Use the Speed of Sound Equation

s = d / t

Answers

Answer 1
7500m because 1,500 in 1 sec so 1500x5 7500

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.

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

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

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."

FirestormOn March 25, 1911, the Triangle Shirtwaist Factory in New York City caught fire. The factory was located on the eighth, ninth, and tenth floors of a building, and later investigations revealed that the factory owners had locked the doors to the stairwells and exits to discourage workers from taking unauthorized breaks and to prevent theft. The fire was one of the deadliest industrial disasters in history--146 workers died from the burns, smoke inhalation, or falling or jumping to their deaths. Most of the victims were young women who had recently immigrated to the United States. Hero(ine)Captain John Smith was one of the leaders of Jamestown, the first English settlement in North American. He had many encounters with Native Americans--some were friendly exchanges, and some involved violence. However, his most famous encounter--the one involving Pocahontas, the Powhatan chief's daughter, may not have actually happened. Smith made no mention of the meeting in his original diaries but described the event many years later when he wrote and published his experiences in a travel book meant to get Englishmen interested in moving to America.
