the output voltage of the transformer that has 1,000 turns of wire in the primary coil and 50 turns in the secondary coil is 120 V
What is a transformer?A transformer is an electrical device that transfer electric energy from one circuit to another.
To calculate the output voltage of the transformer, we use the formula below.
Formula:
V/V' = N/N'........... Equation 1Where:
V = Primary/input VoltageV' = Secondary/output voltageN = Primary turnsN' = Secondary turnsMake V' the subject of the equation
V' = VN'/N........... Equation 2From the question,
Given:
V = 2400 VN' = 50 turnsN = 1000 turns.Substitute these values into equation 2
V' = (2400×50)/1000V' = 120 VHence, the output voltage of the transformer that has 1,000 turns of wire in the primary coil and 50 turns in the secondary coil is 120 V.

What Daryl said is correct and the relationship among them is a causation than a correlation, because we know that high pitched sound wave has more frequency than that of low pitched sound wave. and we also know that if the medium is same then velocity of wave is same* so if there is high pitched sound wave, it has shorter wavelength and if there's low pitched sound wave it has longer wavelength. since there's an inverse relationship between wavelength and frequency.

. Scientific question: Why does a dog circle its bed before lying down?
Write the steps you would take to explore this question using the scientific method.
Answer:
In the scientific method first of all is you need to identify the problem, the problem to your question is why does the dog circle its bed before lying down. Second is the observation to gather some data, you need to observe the dog if what could be the possibility the the dog may do that action. The third is the per hypothesis, you need to came up with an idea why does the dog do such and action for example the needs to find a correct spot to make itself comfortable and lastly the hypothesis, this should answer to your question or your problem. So my hypothesis is that dogs are one of the animals that are those difficult to find a place to sleep and some of that kind of animals are cat, before they lay on their bed, they have to circle to find a spot that could fit its body to be more comfortable when the dog sleep

Space exploration costs the taxpayers of united states millions of dollars each year. However, it is the only way we will learn more information about space. Do you think the cost of space exploration is justified or should those tax dollars be spent elsewhere? Explain your answer.
The space exploration program should continue, and should receive continued generous annual funding.
The US space program has NEVER launched a capsule full of money into space. NEVER ! The money spent on the space program is paid to hundreds of thousands of employees and contractors who design, develop, build, and launch the spacecraft and the scientific equipment they carry.
These people who get the money spend it to buy homes, cars, clothes, beer and bread, and send their children to school ... exactly the same things other Americans do with the money they earn on their jobs.
Just because the most visible product of this industry gets shot into space and never comes back does NOT mean that the money to do it is also lost forever. It's taxpayer money that the government pours straight back into the nation's economy, through the hands of the workers and scientists who operate the US space program.

what is one watt power?
Answer:
1-watt power is defined as the power produced when 1 Joule of work is done for 1 second.
Explanation:
Hope this helps! Please let me know if you need more help or think my answer is incorrect. Brainliest would be MUCH appreciated. Have a wonderful day!
Answer:
In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit).

4. If it requires 19,208 J to lift an object in 10s, how much power is needed?
Answer:
1920.8
Explanation:
If the object is lifted straight up at constant speed, then the force needed to lift it is equal to its weight mg. The work done on the mass is then W = Fd = mgh. We define this to be the gravitational potential energy (PEg) put into (or gained by) the object-Earth system
You serve a volleyball with a mass of 2.1kg the ball leaves your hand with a speed of 30 m/s. What is the kinetic energy of the ball?
Answer:
945 joules
Explanation:
the formula for kenetic energy is:
0.5 × m × v^2
where m is in (kg) ane (v) is in meter per second.
so we can just use the formula;
0.5 × 2.1 × 30^2
so the answer is 945 joules

4. The pressure under the tyres of a tractor is 60 000 Pa. The pressed area is 0.5 m². How much
is the weight of the tractor?
Answer:
weight = 30000 Newton
Given:
pressure: 60,000 Paarea: 0.5 m²========================
[tex]\sf pressure \ (Pa)=\dfrac{force \ (N)}{area \ (m^2)}[/tex]
[tex]\dashrightarrow \sf \ 60 000 = \dfrac{force}{0.5}[/tex]
[tex]\dashrightarrow \sf \ force =60 000 *0.5[/tex]
[tex]\dashrightarrow \sf \ force =30000 \ N[/tex]
========================
Weight is the force due to gravity.
Thus, force = gravity = 30000 N
What kind of particles exert electric force?
When working with a conservative force, it is generally easier to work with a potential energy function, which is a scalar, than to compute the work along some path from the forces and displacements, which are vectors. the change in the potential energy of an object depends only upon its initial and final position, but it is independent of the path undertaken to move between those positions. some effort is initially required to obtain the potential energy function. consider a block of mass m attached to the end of a horizontal hooke's law spring with spring constant k. the block is free to move along a frictionless horizontal surface, and displacements are measured from the equilibrium position of the spring, taken here as the origin of the coordinate system.
a = fs = - k x iì‚
b = ds = dx iì‚
c = dw = - k x dx
d = dus = k x dx
required:
a. a finite change in the potential energy may be obtained by integrating infinitesimal changes. what integral expressions is correct for this hooke's law spring?
b. perform the integrations, and input an expression for the change in the potential energy of the spring, also known as the elastic potential energy.
a. The integral expression for the change in potential energy of the spring is ΔU = ∫kxdx
b. The change in potential energy of the spring is ΔU = k(x₂² - x₁²)/2
Since we are given the differential elastic potential energy, du, to find the integral expression, we integrate du.
a. The integral expression for the change in potential energy of the springThe integral expression for the change in potential energy of the spring is ΔU = ∫kxdx
Since the infinitesimal elastic potential energy of the spring du = kxdx, integrating both sides of the expression, we have
ΔU = ∫du
ΔU = ∫kxdx
So, the integral expression for the change in potential energy of the spring is ΔU = ∫kxdx
b. The elastic potential energy of the springThe change in potential energy of the spring is ΔU = k(x₂² - x₁²)/2
Performing the integration for the change in potential energy of the spring
ΔU, we have that integrating for change in length from x₁ to x₂
ΔU = ∫kxdx
ΔU = k[x²/2]₁²
ΔU = kx₂²/2 - kx₁²/2
ΔU = k(x₂² - x₁²)/2
So, the change in potential energy of the spring is ΔU = k(x₂² - x₁²)/2
