good afternoon______________✌️✌️✌️✌️



Force is PRODUCT of mass and acceleration.

F=m×a

Units:

m=kg

a=m/(s×s)

F=kgm/(s×s)

Five additions of organic farming

Answer» BUILDING Soil Fertility

Organic farmers build and maintain soil fertility through a number of PRACTICES that mimic the natural ECOSYSTEM, rather than supplying crop needs through application of chemical, fossil fuel-derived commercial fertilizers. One characteristic of organic farmers is their strong belief in the soil as a complex place that is home to a living ecosystem of billions of organisms that work together to provide cycling of nutrients, and not merely a physical medium that holds plants UPRIGHT and provides a place to store chemical nutrients until they are taken up by plants. The care of this living system and the cycling of its nutrients in field crops, vegetables, pastures, and domestic animals are central to the philosophy of organic farming and a foundation on which farmers build sustainable systems.

What is atmospheric pressure and cause of atmospheric pressure?Please tell me in short

Answer»

The PRESSURE exerted by the weight of the atmosphere, which at sea level has a MEAN value of 101,325 pascals (roughly 14.6959 pounds per square inch) is KNOWN as atmospheric pressure.

Atmospheric pressure is CAUSED by the weight of the atmosphere pushing down on itself and on the surface below it. Pressure is defined as the force acting on an object divided by the AREA upon which the force is acting.

Frequency of sound -

Number of waves passes per UNIT time is termed as Frequency.
So, number of sound waves (vibration) PASSING per unit time is CALLED Frequency of sound.

It's unit is Hertz (Hz).

Frequency is considered as a property of wave.

Answers SCIENCE GCSE

What is the difference between aerobic and anaerobic respiration?

315326 VIEWS  

Both aerobic and anaerobic respirationinvolve chemical reactions which take place in the cell to produce energy, which is needed for active processes.
Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. The chemical equation is C6H12O6 + 6O2 → 6CO2 + 6H2O (glucose + oxygen -> carbon dioxide + water). 
Anaerobic respiration also produces energy and USES glucose, but it produces less energy and does not require oxygen. This is useful in tissues which have a high energy demand such as in working muscles, in which there is not enough oxygen to produce all the energy needed by using aerobic respiration alone. Anaerobic respiration takes place in the cell cytoplasm and produces lactic acid. The chemical equation is C6H12O6 -> 2C3H6O3 (Glucose -> Lactic acid)

What is loudness?How sound measure?

Answer»

A SURPRISINGLY complicated question.Volume -the absolutephysical property of the power of sound, ismeasured in decibels.That gives you the SPL - sound pressure level. A decibel isn’t used just for sound, it’s a ratio of properties - in this case the pressure (measured in pascals) relative to a reference. On earth, pretty much the max value for sound pressure is around 190db, although the human threshold for pain is much lower, around 130 and hearing damage can start even lower still.Loudness, however, is trickier. It’s generally a perceptivething, and the human BRAIN does not perceive loudness evenly across the frequency spectrum or over time. Our brains are optimized to be more sensitive to sounds in the high midrange (where a lotof the “clarity” of spoken speech is) and not as much in the more extreme lows and highs. You can have a sound with a very high SPL that doesn’t sound as“loud” as you’d think because the frequency isn’t well-perceived by your brain.Dynamic range plays tricks on your brain, too. You can have two speakers each set to the same level, playing MUSIC (for example) that has thesame peak value, andone can sound louder than the other, because of the overallaverage power. However over time, the “loud” one stops SEEMING so loud, as the brain sort of auto-adjusts to continual loud sounds.Loudness is still sometimes roughly measured in decibels,although instead of a momentary measurement it’s an average power acrossthe spectrum - the root-mean square. These days, though, loudness is generally more accurately measured in Loudness Units (Full Scale), or LUFS. It’s similar to the RMS except it’s adjusted for human frequency perception. It’s also broken down into momentary (an individual snapshot), short term (loudness over a short window of time) and INTEGRATED (loudness over the duration of the sound).
