The note "Middle C" is known to have a frequency of 261.6 Hz. What would

Physics
1 answer:
Gwar [14]3 years ago
8 0

Answer: frequency = 523.2 Hz

Explanation:

One octave higher = 2f of the last octave.

For instance, if C2 = 4 Hz

A octave higher will be C3 in which its frequency will be 2 × 4Hz = 8Hz

Back to the question.

One octave higher frequency will therefore equal to:

2f = 2 × 261.6 = 523.2 Hz

Describe the sun. Include its structure (layers), relative size, location, and effects of its magnetic field. Where does the sun
Salsk061 [2.6K]

Answer: Nuclear fusion.

Explanation: The sun is a medium-sized star, its radius is  695.510 km and its mass is equivalent to that obtained by bringing together about 110 planets equal to Earth (6371 km is its radius).

It has six layers: The core, the radioactive zone, the convective zone, the photosphere, the chromosphere and the corona.

Magnetic field disruptions near active regions can generate strong explosions in the sun such as sun flashes and coronal mass ejections. The degree of complexity of the sun´s magnetic field increases and decreases with the course of each sunspot cycle.  

Sir Arthur Eddington was the first to evaluate all the data and dared to conjecture that nuclear fusion, the process that creates heavy elements from the fusion of lighter ones, could be responsible for the great production of the sun´s energy; this process make the sun´s energy was taken for the earth and the planet get back to the sun recycled energy. The sun has a very large and complex magnetic field; the average magnetic field of the sun is approximately 1 Gauss, almost twice as strong as the average magnetic field of the Earth´s surface (approximately 0.5 Gauss). Because the surface of the sun is more than 12.000 times larger than the Earth, the overall influence of the sun´s magnetic field is immensely large.

True or false energy is always lost in a circuit
Llana [10]

Explanation:

Electrons will gain energy as they are "pushed" from different points in the circuit. This energy is then lost when the electrons flow through circuit components such as a light bulb.

HELP PLEASE 
-BARSIC- [3]
Angel !  You have a formula, and you have an example that's
completely worked out.  The ONLY POSSIBLE reason that you
could still need help is that you're letting math scare you.

I'll do 'A' for you, 'B' most of the way, and get 'C' set up.
If THAT's not enough for you to run with and finish them all,
then you and I should both be embarrassed.

Write the formula on the wall:

                                   °F  =  (9/5) °C  +  32°

A).  Convert 35° C        °F  =  (9/5)(35°) + 32°

(9/5)(35) = 63              °F  =      63°      + 32°

                                     °F  =  95°
____________________________________

B).  Convert 80°F to °C 
                         The formula:    °F  =  (9/5) °C  +  32°

°F = 80                                     80  =  (9/5)°C  +  32

Subtract 32 from each side:      48 = (9/5)°C

Multiply each side by  5 :        240  =  (9) C

Now you take over:
_________________________________________

C).  Convert 15°C to °F.
                         The formula:    °F  =  (9/5) °C  +  32°

°C = 15                                      °F = (9/5) 15° + 32

(9/5) (15) = 27     
                             Go !              °F  =
