Answer:

sound is the answer, I'm not sure why I'd think it was because it creates a vacuum

Answer:

sound

Explanation:

Sound travels as waves of energy, but, unlike light, the waves transmit energy by changing the motion of particles.

Answer:

When a polythene rod is rubbed with a duster, the friction causes electrons to gain energy. Electrons gain enough energy to leave the atom and 'rub off' onto the polythene rod. The polythene rod has gained electrons, giving it a negative charge.

Answer:

            T = reading (cm) time base (s / cm)

            f = 1 / T

Explanation:

An oscilloscope is a piece of equipment that allows you to visualize and measure a wave that reaches you, in the case of having a sonometer this transforms the sound wave into an electrical signal to be introduced through one of the voltage channels of the equipment, on the screen we will see the oscillating alternating signal, if it is fixed we can make the reading, if it is moving the time base and the trigger must be adjusted to stop it.

In the oscilloscope we can read the period of the signal, this is the time it takes for the signal to repeat itself with this value, we can calculate the frequency with the formula, for the reading of the period the distance is measured on the labeled screen and multiplied by the time base

            T = reading (cm) time base (s / cm)

            f = 1 / T

Answer:

a current will be induced.

Explanation:

Answer:

Explanation:Sample Response: A current will not be induced because the wire is not part of a closed circuit. The electrons have no place to flow to.

The wire is not part of a closed circuit.

Answer:

1.Latitude forms an inverse relationship with temperature, where regions at lower latitudes have higher temperatures compared to areas at higher latitudes. The lower the latitude, the warmer the region becomes. Conversely, the higher the latitude, the colder the area becomes.

2.Latitude and longitude make up the grid system that helps humans identify absolute, or exact, locations on the Earth's surface. There is a relationship between latitude and temperature around the world, as temperatures are typically warmer approaching the Equator and cooler approaching the Poles.

Answer:

3.43 A

Explanation:

Applying,

V = IR'.............. Equation 1

Where V = Voltage, I = current, R' = Total resistance

Make I the subject of the equation

I = V/R'........... Equation 2

From the question

Given: V = 120 volt, R' = (12+23) = 35 0hm

Substitute these values into equation 2

I = 120/35

I = 3.43 A

1. Answer:

It allows scientists to predict things about objects that are too small to see.

Explanation:

Atomic models are crucial to the scientific study of atoms. Through models, we represent atoms that we actually cannot see. Observation based study and testing is done through that model which helps us find flaws in one model so that a better model is made. In this way, it is helpful to study about atoms through atomic models.

2. Answer:

The correct step in a scientific experiment involving acids and bases is:

Using an indicator to measure the hydrogen ion concentration of a solution.

Explanation:

Two acids can never neutralize each other. The pH of a neutral solution is 7. Whereas pH of an acid is always less than 7.

Indicators are used to measure the pH of solutions. They give different colors in solutions with different solutions. So, in an experiment to check if the solution is acidic or basic, we need to measure its hydrogen ion concentration for which an indicator is used.

Explanation:

Probably the most famous force of all is gravity. We humans on earth think of gravity as an apple hitting Isaac Newton on the head. Gravity means that stuff falls down. But this is only our experience of gravity. In truth, just as the earth pulls the apple towards it due to a gravitational force, the apple pulls the earth as well. The thing is, the earth is just so massive that it overwhelms all the gravity interactions of every other object on the planet. Every object with mass exerts a gravitational force on every other object. And there is a formula for calculating the strengths of these forces, as depicted in the diagram below:

Diagram of gravitational forces between two spheres

Diagram of gravitational forces between two spheres

Let’s examine this formula a bit more closely.

F refers to the gravitational force, the vector we ultimately want to compute and pass into our applyForce() function.

G is the universal gravitational constant, which in our world equals 6.67428 x 10^-11 meters cubed per kilogram per second squared. This is a pretty important number if your name is Isaac Newton or Albert Einstein. It’s not an important number if you are a ProcessingJS programmer. Again, it’s a constant that we can use to make the forces in our world weaker or stronger. Just making it equal to one and ignoring it isn’t such a terrible choice either.

m_1m  

1

​  

m, start subscript, 1, end subscript and m_2m  

2

​  

m, start subscript, 2, end subscript are the masses of objects 1 and 2. As we saw with Newton’s second law (\vec{F} = M\vec{A}  

F

=M  

A

F, with, vector, on top, equals, M, A, with, vector, on top), mass is also something we could choose to ignore. After all, shapes drawn on the screen don’t actually have a physical mass. However, if we keep these values, we can create more interesting simulations in which “bigger” objects exert a stronger gravitational force than smaller ones.

\hat{r}  

r

^

r, with, hat, on top refers to the unit vector pointing from object 1 to object 2. As we’ll see in a moment, we can compute this direction vector by subtracting the location of one object from the other.

r^2r  

2

r, squared refers to the distance between the two objects squared. Let’s take a moment to think about this a bit more. With everything on the top of the formula—G, m_1m  

1

​  

m, start subscript, 1, end subscript, m_2m  

2

​  

m, start subscript, 2, end subscript—the bigger its value, the stronger the force. Big mass, big force. Big G, big force. Now, when we divide by something, we have the opposite. The strength of the force is inversely proportional to the distance squared. The farther away an object is, the weaker the force; the closer, the stronger.

Hopefully by now the formula makes some sense to us. We’ve looked at a diagram and dissected the individual components of the formula. Now it’s time to figure out how we translate the math into ProcessingJS code. Let’s make the following assumptions.

We have two objects, and:

Each object has a PVector location: location1 and location2.

Each object has a numeric mass: mass1 and mass2.

There is a numeric variable G for the universal gravitational constant.

Given these assumptions, we want to compute a PVector force, the force of gravity. We’ll do it in two parts. First, we’ll compute the direction of the force \hat{r}  

r

^

r, with, hat, on top in the formula above. Second, we’ll calculate the strength of the force according to the masses and distance.

Remember when we figured out how to have an object accelerate towards the mouse? We're going to use the same logic.

Usando la ecuación ideal de los gases.

[tex]PV=nRT[/tex]

Debemos recordar, que CNPT significa condiciones normales de presión y temperatura.

Para el primer estado tenemos:

[tex]P_{1}V_{1}=nRT_{1}[/tex]

Donde:

Para el segundo estado:

[tex]P_{2}V_{2}=nRT_{2}[/tex]

Donde:

Como ambas ecuaciones tienen el mismo valor de volumen podemos igualarlas:

[tex]\frac{nRT_{1}}{P_{1}}=\frac{nRT_{2}}{P_{2}}[/tex]

n y R permanecen constantes, se puden cancelar.

[tex]\frac{T_{1}}{P_{1}}=\frac{T_{2}}{P_{2}}[/tex]

Despejamos P(2).

[tex]P_{2}=\frac{P_{1}T_{2}}{T_{1}}[/tex]

[tex]P_{2}=\frac{1*313}{298}[/tex]

[tex]P_{2}=1.05\: atm[/tex]

Answer:

When the obstacle is fixed, the law of action and reaction, makes the reflected wave is inverted.

When the obstacle is mobile, he mobile point, it moves in the direction of the wave, therefore there is no inversion of it.

Explanation:

Waves when they reach an obstacle behave like a shock, therefore if we use the conservation of momentum the wave must reverse its speed, this explains that the speed changes sign, the wave is reflected.

When the obstacle is fixed, the wave when it reaches the obstacle exerts a force on the point, by the law of action and reaction the point exerts on the wave a force of equal magnitude but in the opposite direction, this reaction force which makes the reflected wave is inverted.

When the obstacle is mobile, this is without friction, when the wave arrives it exerts a force on the mobile point, it moves in the direction of the wave, reaching the maximum amplitude of the incident wave, when it is reflected the point begins to go down along with the wave, therefore there is no inversion of it.
