Basically, the Parametric EQ divides the audio spectrum into three bands, allowing you to enhance (or suppress) the level in that range.

Answer:

I think this statement is true at least in modern day times. The world runs on nothing but technology. People use more technology instead of old school textbooks and papers. Imagine living in a world without technology… that means no cars, no trains, no devices, no machines like your stove or printer, no lights and lots more. John Wesley is 100 percent correct with this statement. Electricity is indeed the powerhouse of the universe.

Given,

length of object, [tex]h_o = 3 cm[/tex]

We know, for flat refracting surface,  

Image distance = object distance

So,

magnification is = [tex]-1[/tex]

length of the image,

[tex]h_i = magnification * h_o\\\\h_i = -1 * 3 \\\\h_i = -3cm[/tex]

Here, negative sign means inverted image.

Explanation:

The order of the location of each process in the carbon cycle are as follows;

Reasons:

Ingestion; During the ingestion process, the products of the direct Sunlight and photosynthesis, which

are energy rich chemical substances are ingested by herbivores.

Decomposition; The plants and animals die and undergo decomposition.

Fossilization; A long period the decomposed plants and animals manifest

into hard petrified materials, with their parts transformed to fossils.

Combustion; The remains of plants and animals, subjected to heat and

pressure due to compression, as when as bacteria decomposition that

removes several other elements, leaving a carbon and hydrogen rich

sludge that can be processed into fuel used for combustion. The

combustion process produces carbon dioxide which restarts the cycle.

Hi there!

Recall that:

Change in momentum = mass × change in velocity

Or:

Δp = mΔv = m(vf - vi)

Plug in the given values. We can assign east to be positive and west to be negative in this instance (Velocity is a vector with direction).

Thus:

Δp = (1)(-21 - 10) = -31 kgm/s OR 31 kgm/s WEST.

The correct answer is B.

Change in momentum is EQUIVALENT to the quantity of IMPULSE.

The correct answer is H.

Answer:

Explanation:

White dwarf, Sun, red supergiant shows the stars in the correct order, from smallest in size to largest.

More than 1.4 million kilometers span our Sun. However, not every star is the same size. They range in size from that of a metropolis to that of our solar system's half!

The mass of neutron stars is concentrated into a very compact area. Even though they are frequently only 20 to 40 km in diameter, they may hold the mass of one or two Suns. White dwarf stars are a little larger and frequently resemble the size of the Earth.

Compared to our Sun, the greatest supergiant stars can be more than 1500 times bigger. They are now more than 2,000 million kilometres across. Supergiants don't, however, have thousands of times the mass of the Sun. The reason for this is that as supergiants become older, their interiors become considerably more dispersed. Betelgeuse, a red giant in Orion's constellation, is nearly 1000 times broader than the Sun yet only has around 15 times as much mass.

Answer:

there very old

Explanation:

Answer: 250n

Explanation:

The formula for gravitational force is: F = (gMm)/r^2

There are two factors at play here:

1) The mass of the planet 'M'

2) The radius 'r'

We can ignore the small M and the g, they are constants that do not alter the outcome of this question.

You can see that both M and r are double that of earth. So lets say earth has M=1 and r=1. Then, new planet would have M=2 and r=2. Let's sub these two sets into the equation:

Earth. F =  M/r^2 = 1/1

New planet. F = M/r^2 = 2/4 = 1/2

So you can see that the force on the new planet is half of that felt on Earth.

The question tells us that the force on earth is 500n for this person, so then on the new planet it would be half! So, 250n!

Explanation:

The federal income tax withholding for each biweekly paycheck for the single teacher is $259.9.

The given parameters:

Biweekly amount earned by the single teacher, = $1,500

The federal tax rate for single workers is given as;

amount between $436 and $1,506 = $34.9 plus 15%

The federal income tax withholding for each biweekly paycheck for the single teacher is calculated as follows;

income tax withholding = $34.9  +  0.15($1,500)

income tax withholding = $34.9  +  $225

income tax withholding  = $259.9

Thus, the federal income tax withholding for each biweekly paycheck for the single teacher is $259.9.

Explanation:

Final velocity=Initial velocity+(acceleration×time)

4 ways to find initial velocity:

1) Initial velocity=Final velocity-(acceleration×time)

2) Initial velocity=(Distance/Time)-((acceleration×time)/2)

3) Initial velocity=√Final velocity-(2×(acceleration×distance))

4) Initial velocity=2(distance/time)-Final velocity

Total force = Mass×Acceleration

Explanation:

H=gt^2/2

At any point along the track, the rollercoaster's mechanical energy is equal to the sum of its potential and kinetic energies,

M = P + K

and we assume the coaster's total mechanical energy is conserved throughout its motion along the track, so that M is the same at every point.

At the first point,

K + 75,000 J = 90,000 J   ⇒   K = 15,000 J

At the second point, since M = 90,000 J everywhere,

K + 45,000 J = M   ⇒   K = 45,000 J

At the third point,

K + 0 J = M   ⇒   K = 90,000 J

The same principles apply to the pendulum, so M = 5,100 J throughout its swing.

At the first point,

K + 4,500 J = 5,100 J   ⇒   K = 600 J

At the second point,

K + 0 J = M   ⇒   K = 5,100 J

At the third point,

600 J + P = M   ⇒   P = 4,500 J
