Answer:
When oil is spilled in the sea it will normally break up and be dissipated or scattered into the marine environment over time. This dissipation is a result of a number of chemical and physical processes that change the compounds that make up oil when it is spilled. The processes are collectively known as weathering.

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?
Answers
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

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.

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.
Answers
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.
Determino la masa en gramos y kilogramos de 1500 cm3 de alcohol etílico, cuya densidad es aproximadamente 790.0 Kg/m3. Tomar en cuenta que: Densidad (ρ) = masa (m)/volumen(v).
Answers
Para calcular el contenido en gramos de una bebida alcohólica basta con multiplicar los grados de la misma por la densidad del alcohol (0,8). El contenido de alcohol de una bebida depende de la concentración de alcohol y del volumen contenido.
The mass in grams and in kilograms of ethyl alcohol respectively is: a) 1185.0 g and b) 1185 kg
What is density?Density is an intensive property of matter. It represents the relationship between the mass and the volume of a body or substance. Its units are in the International System kg/m3, kg/L, g/ml, g/cm3, among others.
The density formula is:Density = m/V
The mass is obtained by clearing this equation
m=Density *Volume
datam= ?
V= 1500 cm3 * 1 * 10⁻⁶ m³ / 1 cm³ = 0.0015 m³ = 1.5 * 10⁻³ m₃
Density= 790.0 kg/m3
m = 790.0 kg/m³ * 1.5 * 10⁻³m³ = 1.185 Kgm = 1.185 kg * 1000 g/ 1 kg = 1185,0 gm= 1185,0 gSee more about this at:https://brainly.com/question/23704878what is one watt power?

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.

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.
Answers
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
