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).

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

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.

Density = m/V

The mass is obtained by clearing this equation

m=Density *Volume

m= ?

V= 1500 cm3 * 1 * 10⁻⁶ m³ / 1 cm³ = 0.0015 m³ = 1.5 * 10⁻³ m₃

Density= 790.0 kg/m3

 B C     I suppose , though A is correct too

Explanation:

The arrows on the magnetic field lines point from the magnet's north pole to its south pole. The field lines are closest together in and near the magnet. Thus, the correct options are B and C.

Magnetic force is the force of the electrically charged particles which are in motion, such as attraction, or repulsion results from their activity. It is the fundamental force behind the phenomena like how electric motors operate and magnets are drawn to metals.

Usually, when we draw magnetic field lines, we start to draw outwardly from the North pole to the South Pole. This same direction is prevalent on the Earth due to the fact that the Earth functions as a giant magnet. Thus, the model describes that the magnetic field lines will spread out of the north end of the magnet to the south end. The magnetic field lines are closest in and near the magnet.

Therefore, the correct options are B and C.

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.

The 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

The 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

Answer:

-13.5 m/s^2

-1.35m/s

Explanation

First, find the momentum of the paintball by using the formula [tex]p=mv[/tex].

[tex]p=0.15*45[/tex]

[tex]p = 6.75[/tex]

The next step would be to find the change of momentum of the gun. Since the gun was at rest it had a momentum of 0. Momentum acts in different directions equally, therefore we can set up the equation for the acceleration:

FΔt=Δp

Where F is force, Δt is the change of time and Δp is the change of momentum.

Since we solve for acceleration, we can convert F to ma to get:

maΔt=Δp

Substitute values:

5a*(0.1-0)=-6.75

5a=-67.5

a=-13.5

Our a is -13.5m/s^2, it's negative since the direction it's acting on is opposite of the paintball.

Now we can find velocity (and double-check our work!).

The first way to solve for velocity is:

[tex]V=Vi+at[/tex]

Where V is final velocity, Vi is initial, a is acceleration and t is time.

substitute values:

[tex]V=0-13.5*0.1\\V=-1.35m/s[/tex]

If we are correct, using the formula p=mv, we should get the same result (remember, our momentum is negative).

[tex]p=mv\\-6.75=5v\\-1.35m/s=v[/tex]

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.
