How many psi in 29.92 in hg.?

29.92 inches of mercury, which is the average atmospheric pressure on Earth at sea level, is about 14.7 pounds per square inch.

What parts of the body are affected by space travel?

If a body would be teleported into space, far way from any star, the present heat of the body would be lost to the vacuum around it and the body temperature would drop to about -270° Celsius. Not to the complete minimum temperature of -273° Celsius, because the radiation in space would not let it drop that far. But these 3 degrees do not make much of a difference.

But if the body is at least near a star like the Sun, in a distance like Earth, the parts of the body which are hit by sunlight would warm up. Maybe they reach -100° Celsius, maybe even +100° Celsius, it depends on the radiation absorption and radiation ejection of the surface. A metal surface could reach over +100°, Teflon would reach around 0° Celsius, I have just read on NASA's site. Skin - I don't know. The parts of the body not facing the star would not be heated up much, however.

If the body was in a perfect space suit, this would balance air temperature and air pressure around it and also shield from much of the sun's radiation. Then the missing gravity might still affect human body temperature, indirectly.

A huge space station might even rotate to have gravity similar to earth's surface, in certain parts of the station.

There, psychological effects and X-rays piercing through the hull could still affect human body temperature, but indirectly.

To get a complete picture of "a body in space", you should also consider the missing pressure in vacuum, but for a human body this is a horrible picture.

well young padawan, it all starts with hitting puberty. your body is affected by increasing the temperature to insane levels. your bodily fluids can reach to temperatures of 10000000000 degrees celcius!!! fancy that

Why does a wet suger is lighter then dry suger?

When sugar is wet, it absorbs some of the water, increasing its volume but not its weight. This can create the illusion that wet sugar is lighter when measured by volume, but its actual weight remains the same as dry sugar.

What major appliance uses the most energy dishwasher or refrigerator dryer?

The refrigerator typically uses more energy than the dishwasher or dryer because it runs continuously to keep the food inside cool. Dishwashers and dryers consume a lot of energy during their operation, but they are not constantly running like a refrigerator.

What is the difference between oscillator and feedback amplifier?

There are two differences:

a) the amount of feedback you allow

b) whether you wire a frequency-determining device into the circuit

First things first: ANY amplifier circuit that uses feedback, which these days is most of 'em because feedback improves the quality of an amp's output, will oscillate if there's enough feedback. This poses a real problem because the more feedback you use, the better the amp sounds. Your challenge, therefore, is to make an amp that uses not quite enough feedback to oscillate.

The other is equally critical. If you want oscillation you usually want it on a specific frequency. You can build an LC tank or a crystal into the circuit to determine the output frequency if you're building an oscillator; if you're building an amp you wouldn't do this.

What is the meaning of ThermoBall?

ThermoBall is a synthetic insulation technology developed by The North Face that mimics the insulating properties of down but retains warmth when wet. It is designed to provide lightweight, packable warmth in cold and wet conditions.

Why does pressure decrease with increase in area?

The tighter any given volume the more pressure and vice versa. Look at it it like this: Lets say the volume is increased. This is saying molecules have farther to go and they impact the container walls less often per unit time. This means the pressure will be less because there are less molecule impacts per unit time.

What is the difference between metal-clad and metal-enclosed switchgears?

Metal-Clad Switchgear is an assembly of units characterized by the following features: The main interrupting device is removable and arranged with a mechanism for moving it physically between connected and disconnected positions. It is equipped with self-aligning and self-coupling primary and secondary disconnecting devices. The interrupting devices, buses, voltage transformers, and control power transformers, are completely enclosed by grounded metal barriers, which have no intentional openings between compartments. A metal barrier in front of the interrupting device ensures that when, in the connecting position, no live parts are exposed by the opening of an enclosure door. All live parts are enclosed within grounded metal compartments. The Metal enclosed switchgear assembly consists of multiple metal-enclosed, vertical sections. Normally the end sections are designed to allow for installation of future sections. Each vertical section consists of up to four individually enclosed breaker or auxiliary compartments. Compartments are sized to provide uniform height of each switchgear assembly. Various components such as circuit breakers, instrumentation and control equipment, transformers, relays, three-phase bus work, all internal wiring, connectors, and other supporting equipment are included in each assembly. These units can be directly coupled to 480V motor control centers if desired

What is required to set an object in motion?

To set an object in motion, you need to apply a force to overcome any inertia the object may have. This force can come from pushing, pulling, or applying energy to the object in some form. Once the force is applied, the object will begin to move in the direction of the force.

Is the energy stored in a compressed spring called strain energy?

Yes, the energy stored in a compressed spring is commonly referred to as potential energy, specifically elastic potential energy. The spring store this energy by virtue of its deformation or change in shape due to compression.

What is the purpose of the coil in a speaker?

The coil in a speaker, often called the voice coil, is used to convert electrical signals into mechanical vibrations (sound). When an electrical current passes through the coil, it interacts with the magnetic field of the speaker, causing the coil to move back and forth rapidly, which in turn creates sound waves.

What part of the atom is moving through the circuit?

In a circuit, it is the electrons that move through the wires and components. Electrons are negatively charged particles that flow from the negative terminal of the voltage source (such as a battery) towards the positive terminal.
