A sound of 20 dB intensity is twice as loud as one of 10dB?
No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10.

How many dB of attenuation translates into 50 percent of the voltage being lost to attenuation?
db=20log(V1/V2) or 10log(P1/P2) Example: db=20log (100/50) db=20log(2) db=20*.3010 db=6.02
What color is lighter db 701 or db 703?
DB701 is lighter (They are German Railway Colours - Deutsche Bahn = DB)
Is there more energy in a 30 dB or 40dB sound wave?
40 dB has ten times the power of 30 dB. 50 dB has another ten times as much power.
What is Montgomery db 4265c?
MONTGOMERY DB 4265 C is an automotive body in white approved lubricant for medium to severe stamping and drawing. It is approved for use by GM, Ford, Chrysler, Volkswagen, Honda and Nissan. It provides excellent drawing lubricity for fine part finishes. It is recommended for all coated and uncoated steel and aluminum. This product is used on body panels and structural parts.
Are solar panels ac or DC?
They are DC
What is the area of a rhombus if ac is 14cm and db is 8cm?
AC and DB must be the diagonals of the rhombus, because the sides are all equal. Area = product of the diagonals. = 14 x 8 = 112
How are sola panels used?
Solar panels create DC current that is then converted into AC current for electricity usage.
What is the area of this rhombus if AC equals 14 cm DB equals 8 cm?
112
What is needed to run a power stations?
sunlight and photovoltaic panels (solar cells/panels) also electronic power inverters to change the DC from the panels into AC to send to the power grid.
What is the dB level for 15 hp AC electric motor?
This will depend on the motor. You should ask the manufacturer.
What is needed to run a solar power station?
sunlight and photovoltaic panels (solar cells/panels) also electronic power inverters to change the DC from the panels into AC to send to the power grid.
Is AC DC the same as AC db?
No, db is a measurement of decibels/signal loss or gain. AC (alternating current) is an electric waveform that varies from positive to negative like you would have in your home or off a transformer, DC (direct current) is a constant value with reference to another point like from battery power or your car. Some devices and appliances will run on both types of power which is why they say ac/dc compatible.
AC equals 14 cm DB equals 8 cm What is the area of this rhombus?
56 cm squared
What's a good noise level for a really quiet air conditioner?
An AC runs at a quiet would be 40 dB.
What are the components of a photovoltaic system?
Panels (photovoltaic induction), inverters (dc to ac inversion) and a host system (transmit/store).
How do solar panels produce electricity for your home?
Solar panels produce electricity for your home in the following manner. Silicon in the panels absorb photons produced by the sun. The panel then converts this energy to a DC current and channels this to a converter. The converter turns this into AC poers and channels it through the home.
