A helix with 17 turns has height H and radius R. Charge is distributed on the helix so that the charge density increases like (i
marishachu [46]

The total charge on the helix is

  • Q = \frac{221}{2}\sqrt{(\frac{H}{17})^2+(2\piR)^2

Height of one turn = \frac{H}{n}

Horizontal distance in one turn = 2\pi R

<h3>length of spring in one turn is</h3>

l = \sqrt{h^2+(2\piR)^2}\\\\&#10;l = \sqrt{(\frac{H}{n})^2+(2\piR)^2}&#10;

So, the total length of spring

L = n*l\\\\&#10;L = n * \sqrt{(\frac{H}{n})^2+(2\piR)^2}&#10;

Therefore, charge on spring

Q = \frac{1}{2}*L*(13-0)\\\\&#10;Q = \frac{1}{2}*n\sqrt{(\frac{H}{n})^2+(2\piR)^2}*13\\\\&#10;Q = \frac{1}{2}*17*13\sqrt{(\frac{H}{17})^2+(2\piR)^2}\\\\&#10;Q = \frac{221}{2}\sqrt{(\frac{H}{17})^2+(2\piR)^2\\\\&#10;

Look at the Sankey diagram for a filament light bulb below. If the bulb is used in a desk lamp, what is the efficiency of the bu
guapka [62]

Answer:

The question does not state how the answer is to be entered. I would use 10% because that is most common.

Explanation:

You are using 300 J of energy to get 30 J of light energy. The fact that you can account for the left over energy is not relevant.

Efficiency = Work Out / Work In

Efficiency = 30 J / 300 J  = 0.1

If you need this as a %, you can multiply by 100

Efficiency = 0.1 * 100 = 10%

Novay_Z [31]

Answer:

it is the Hubble law

Explanation:

Hubble's law, also known as the Hubble–Lemaître law, is the observation in physical cosmology that galaxies are moving away from the Earth at speeds proportional to their distance. In other words, the farther they are the faster they are moving away from Earth.
