Answer: about 1,100,000,000 to 1,500,000,000 Joules/second

Explanation:

1 MW (megawatt) = 1,000,000.00 J/s (joules per second)

1100(1,000,000) = 1,100,000,000

1500(1,000,000) = 1,500,000,000

How is a pareto chart different from a standard vertical bar graph?

Alona [7]

Answer:

A Pareto chart, named after an Italian economist, combines a bar chart with a line graph. The bar chart is different from a histogram in more than one way. For example, the vertical bars need not touch one another as per a histogram

A mass of 0.250 kg is attached to a spring and undergoes simple harmonic oscillations with a period of 0.640 s. What is the forc

Paha777 [63]

The force constant of the spring is approximately 24.038 newtons per meter.

As we are talking about Simple Harmonic Motion. In this exercise we need to determine the Spring Constant ( $k$ ), in newtons per meter, from the equation of the Period ( $T$ ), in seconds, which is described below:

$T = 2\pi\cdot \sqrt{\frac{m}{k} }$ (1)

Where $m$ is the mass of the moving element, in kilograms.

If we know that $T = 0.640\,s$ and $m = 0.250\,kg$ , then the spring constant of the spring is:

$0.640 = 2\pi\cdot \sqrt{\frac{0.250}{k} }$

$\sqrt{\frac{0.250}{k} } \approx 0.102$

$\frac{0.250}{k} \approx 0.0104$

$k \approx 24.038\,\frac{N}{m}$

The force constant of the spring is approximately 24.038 newtons per meter.

The change in the internal energy of a system that releases 2,500 j of heat and that does 7,655 j of work on the surroundings is

g100num [7]

We are given that the system “releases” heat of 2,500 J, and that it “does work on the surroundings” by 7,655 J.

The highlighted words releases and does work on the surroundings all refers to that it is the system itself which expends energy to do those things. Therefore the action of releasing heat and doing work has both magnitudes of negative value. Therefore:

heat released = - 2, 500 J

work done = - 7, 655 J

Which means that the total internal energy change of the system is:

change in internal energy = heat released + work

<span>change in internal energy = - 2, 500 J + - 7, 655 J</span>

<span>change in internal energy = -10,155 J</span>

You use a very sensitive instrument to measure the speed of sound in your front yard in December. You repeat the test in August

frutty [35]

<h2>Answer: faster </h2>

The speed of sound varies depending on the medium through which the sound waves travel. In addition, it varies with changes in the temperature of the medium. This is because an <u>increase in temperature means that the frequency of interactions between the particles that transport the vibration increases</u>, hence this increase in activity increases the speed. That is why the speed of sound in a gas is not constant, but depends on the temperature.

So, if we want <u>the speed of sound in a gas to increase</u>, the<u> temperature</u> of that gas must <u>increase</u>, as well.

For example, the higher the air temperature, the greater the velocity of propagation. Experiments have shown that the speed of sound in air increases $0.6m/s$ for every $1\°C$ increase in temperature.

Therefore:

<h2>The speed of sound will be faster than in December</h2>
