Why slope of isothermal is les than adiabatic

Answer»

To REACH a same height in a LONGER distance MEANS lower slope of the line. Hence Adiabatic curve is more steeper than Isothermal curve. In-fact, the steepness of Adiabatic curve is times steeper than Isothermal curve. ... And Adiabatic curve has a definite value of slope which is GREATER than 0.

Hybrid pi model bjt common base configuration

Answer»

In electronics, a common-BASE (also known as grounded-base) amplifier is one of THREE basic single-stage bipolar junction transistor(BJT) amplifier topologies, typically used as a CURRENT buffer or voltage amplifier.

In this circuit the emitter terminal of the transistor serves as the input, the collector as the output, and the base is connected to GROUND, or "common", hence its NAME. The analogous field-effect transistor circuit is the common-gate amplifier.

Phase shift oscillator experiment to find frequency

Answer»

In an RC Oscillator CIRCUIT the input is shifted 180o through the amplifier stage and 180oagain through a second inverting stage giving US “180o + 180o = 360o” of phase shift which is effectively the same as 0o thereby giving us the required positive feedback. In other words, the phase shift of the feedback loop should be “0”.

In a Resistance-Capacitance Oscillator or simply an RC Oscillator, we make use of the FACT that a phase shift OCCURS between the input to a RC network and the output from the same network by using RC elements in the feedback branch, for example.

What happens if a refrigerator is not used for a long time

Answer» heya................4.55am

#...
Thanks for the Ask to Answer. 

If you're not going to use a refrigerator for 10 years (which, I'm assuming this means the fridge will remain unplugged for 10 years), then I would initially do the following.

1. Store it in a cool, dry place. Any moisture can contribute to rust, mold, mildew, and so on. Heat can warp the gaskets and/or other components.

2. Defrost and clean your MACHINE properly. You can do this by following the manufacturer's INSTRUCTIONS provided to you when you purchased your unit. If you threw those out (which most folks do), then you can LOCATE instructions by searching for the fridge model number online or by calling the brand and asking them to send you instructions. The instructions will detail the optimal way to clean and defrost your fridge. Usually this ENTAILS leaving the door(s) open for a day or so and deep cleaning with a mild cleaning agent.

3. Ensure it is dry. It's not fun trying to remove mildew and mold. It's even less fun to try to remove the odor.

4. KEEP your fridge upright. See the article below for more info on this. Essentially, if you leave your fridge on its side or back then it's possible that it will transfer internal fluids from the right place to the wrong place.

5. While this isn't ideal, you would do well to check on your fridge every few months. Several months of mold isn't nearly as a bad as several years of mold.

6. Additionally, ask to speak with a technician from the company that made your fridge. They will probably have some good tips for you. Plus, they probably have some decade old refrigerators in storage, too.

Why does specific gravity decrease in wine?

Answer»

Specific gravity is relative to water (S.G. = 1.0) so unfermented wines should be heavier/denser than water, eg S.G. 1.090, YMMV. As the wine ferments the S.G. decreases because the sugars are consumed. This MAKES the S.G. fall. When wine is finished fermenting it can have a S.G. close to or even below 1.000.

To calculate the (approximate) ABV one must know the original gravity and the FINAL gravity of the fermented wine. One must record the starting/original gravity (O.G.) before/at pitching the yeast and SEVERAL successive readings of the specific gravity at later dates. If the specific gravity is the same for three days in a row then the primary fermenting is deemed to have stopped. The LAST specific gravity reading is then the final gravity (F.G.)

How to find velocity of sound using resonance tube

Answer»

This EXPERIMENT the velocity of sound in air is to be found by using tuning forks of known frequency. The wavelength of the sound will be determined by making use of the resonance of an air column.

The apparatus for the experiment consists of a long cylindrical PLASTIC TUBE attached to a water reservoir. The length of the water column may be changed by RAISING or lowering the water level while the tuning fork is held over the open end of the tube. Resonance is indicated by the sudden increase in the intensity of the sound when the column is adjusted to the proper length. The resonance is a standing wave phenomenon in the air column and occurs when the column length is:

λ/4, 3λ/4, 5λ /4

where λ is the sound wavelength.

The water surface constitutes a node of the standing wave since the air is not FREE to move longitudinally. The open end provides the conditions for an antinode, but the actual antinode has been found to occur outside the tube at a distance of about 0.6 r from the end, where r is the tube radius. This end correction may be added to get a more accurate value if only one resonance can be measured, but it is usually more convenient to eliminate this "end effect" by subtracting the resonance length for λ/4 from those for 3 λ /4, 5λ /4, etc.this experiment the velocity of sound in air is to be found by using tuning forks of known frequency.

HOW TO NOT MAKE noise while splashing in the water from a height quora

Answer» heya............4.23

#.......1.
When water is in a mass of joined molecules it behaves LIKE a heavy object. In large masses it has a very thin layer of molecules at the surface, described as the skin. If something is incredibly light like a daddy long legs, it can sit on the surface of water without submerging into the body of it. It is, so light in composition its weight is evenly spread over a large AREA. Its body doesn't break the surface tension of the water molecules, so it can skim across it easily.When something is dense in composition and heavier in weight, it breaks the surface tension molecules with ease.

2. The object entering the water, displaces it (forces the surface water, it is entering, to LIFT up). The sound is the molecules breaking away from each other, and crashing back down into the waters surface again.The molecules REACT in the same way when they land on a hard surface like concrete from a height, or if the water itself is falling from a great height into another body of water, like a waterfall.

3. The weight of the falling water causes a sudden break in the waters surface tension, and has the same effect as continually throwing a heavy object, or material into it.The noise of the splash, is the vibration in air molecules, the sudden break in molecule tension, causes.

What is economical synchronous speed of motor

Answer»

In a motor, synchronous speed is the speed at which the magnetic field rotates. Depending on motor design, the actual mechanical speed may be equivalent (synchronous motor) or slightly smaller (asynchronous motor).

The synchronous speed is a function of:

The electrical FREQUENCY used, typically 60 Hz or 50 Hz.The NUMBER of poles the motor has.

The formula for calculating synchronous speed is:

Sync. Speed (in RPM) = 120 x Frequency (Hz) / # poles

For example, consider a motor with 4 poles operating at 60 Hz:

Sync. RPM = 120 x 60 / 4 = 1,800 RPM

If that same motor was used in a country with a 50 Hz electric supply:

Sync. RPM = 120 x 50 / 4 = 1,500 RPM

Synchronous motors have a DC winding or a permanent magnet in their rotor, and rotate at exactly the synchronous speed. Electric power systems use synchronous generators to ensure that the entire grid has the same frequency.

On the other hand, asynchronous motors generate their rotor field by induction, and rotate slightly below synchronous speed. For example, an asynchronous motor with 4 poles and connected to a 60-Hz supply might rotate at 1750 RPM instead of 1800 RPM. Asynchronous motors are also called induction motors, and there are two main types:

Squirrel-cage motors, which have rods of aluminum or COPPER embedded in the rotor (simulating a cage). Current is induced in these rods, making the rotor spin due to the interaction between the current and the magnetic field.Wound-rotor motors, which have WINDINGS in the rotor to which external resistances can be connected, allowing the motor's speed to be controlled by increasing or decreasing resistance.

Which liquid has the highest surface tension?

Answer»

Water

Because of the relatively HIGH ATTRACTION of water molecules for each other through a web of hydrogen bonds, water has a higher surface TENSION (72.8 milli newtons per meter at 20 °C) COMPARED to that of most other liquids. Surface tension is an important factor in the phenomenon of CAPILLARITY.

Why magnetization increases at low temperature

Answer»

At low temprature the randomness of spins states decrease so therefore magnons and phonons can easily propogate increasing magnetization.

This can ALSO be understood as when in low tempratures randomness in spin states of particles decreases as DEGREE of freedom decreases so now the spins can ALIGN more often increasing magnetization.
