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

Electric currents, changes in electric fields, or charged particles with inherent angular momentum produce the magnetic field.

A magnetic field, a vector field that describes the magnetic field on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field is subject to a force that is perpendicular to the magnetic field and has its own velocity.

The force that draws objects like iron is known as the magnetic force. The attraction or repellence between two magnetic materials is known as magnetic force. Iron is one of the ferromagnetic materials.

Given the facts, the magnetic field is typically present whenever charged particles with intrinsic angular momentum or spin are in the field or space, as well as whenever there are changes in the electric fields or currents.

Now, two of Maxwell's equations explain the magnetic fields produced by electric currents and shifting electric fields.

Magnetic fields are produced whenever a charge moves. When more charge is transferred about, a magnetic field grows stronger.

Hence, when there is an electric field, there is also a magnetic field.

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:

The wavelength of the wave in shallow water is 2.91 m.

Explanation:

Given;

frequency of the wave, f = 1.1 Hz

speed of the wave in deep water, v₁ = 5.7 m/s

speed of the wave in shallow water, v₂ = 3.2 m/s

The wavelength of the wave in the deep water is calculated as;

λ₁ = v₁/f

λ₁ = 5.7 / 1.1

λ₁ = 5.18 m

The wavelength of the wave in the shallow water is calculated as;

λ₂ = v₂/f

λ₂ = 3.2 / 1.1

λ₂ = 2.91 m

Therefore, the wavelength of the wave in shallow water is 2.91 m.

Answer:

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

​  

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

​  

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.

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.

Answer:

the distance traveled by the car is 42.98 m.

Explanation:

Given;

mass of the car, m = 2500 kg

initial velocity of the car, u = 20 m/s

the braking force applied to the car, f = 5620 N

time of motion of the car, t = 2.5 s

The decelaration of the car is calculated as follows;

-F = ma

a = -F/m

a = -5620 / 2500

a = -2.248 m/s²

The distance traveled by the car is calculated as follows;

s = ut + ¹/₂at²

s = (20 x 2.5) + 0.5(-2.248)(2.5²)

s = 50 - 7.025

s = 42.98 m

Therefore, the distance traveled by the car is 42.98 m.

Initial velocity of car is 0.

Final velocity of car is 36 km/h.

Time taken to attain final speed is 2 minutes.

What is the acceleration of car ?

v = u + at

First change the final velocity from km/h to m/s and also time to seconds.

[ To change km/h to m/s multiply by 5/18 ]

➙ Final velocity = 36(5/18) = 10 m/s.

[ 1 minutes = 60 seconds ]

➙ 2 minutes = 2(60) = 120 seconds.

Now, we have

v = 10 m/s.

u = 0 m/s.

t = 120 s.

Hence, the acceleration of car is 0.083 m/s².

➟ The rate of change of velocity is called acceleration. It is denoted by a.

➟ The velocity at which motion starts is termed as initial velocity. It is denote by u.

➟ The last velocity of an object after a period of time. It is denoted by v.

[tex]\boxed{\large{\bold{\blue{ANSWER~:) }}}}[/tex]

By 1st Equation of motion

we know that,

[tex]\boxed{\large{\sf{v \: = u \: + a \: t}}}[/tex]

according to the question,

[tex]10 = 0 + a \times 120\\\\a \: = \frac{10}{120}\\\\a \: = \frac{1}{12}\\\\a=0.083\: m {s}^{ - 2}[/tex]

Therefore,

Acceleration of the car is 0.083 ms^-2

Answer:

Following features are similar in longitudinal and transverse waves: Both waves are mechanical waves. Both transport energy without transporting matter. Particles oscillate about their mean position in both waves.

Answer:

[tex]8\:\text{m/s}[/tex]

Explanation:

From Newton's 2nd Law, we have [tex]\Sigma F=ma[/tex]. Using this, we can find the acceleration of the object:

[tex]9.20=2.30a,\\a=\frac{9.20}{2.30}=4\:\mathrm{m/s^2}[/tex].

Now that we've found the block's acceleration, we can use the following kinematics equation to find its final velocity after 2 seconds:

[tex]v_f=v_i+at,\\v_f=0+4(2),\\v_f=\boxed{8\:\text{m/s}}[/tex]

*Assumption: The block is initially at rest and has a initial velocity of zero. Otherwise, the question is unsolvable.
