Q: describe the negative- feedback system

subject: Science

A: To control the amount of hormones that are in your body, the endocrine system sends chemical messages back and forth within itself. This is called a negative- feedback system.

example:

it works much the way a thermostat works. when the temperature in a room drops below a set level, the thermostat signals the furnace to turn on. once the furnace has raised the temperature in the room to continue to stay off until the thermostat signals that the temperature system controls the level of glucose in your bloodstream.

The next multipole after the octupole is the dodecapole, also known as the 12-pole moment. It contains more information about the distribution of charge or mass in a system compared to lower-order multipoles.

Your body temp is around 30 degrees celcius. Your internal energy of a body is the total amount of energy you preserve. Its kind of like total potential energy, and everytime you move your muscles or do anything you are using that internal energy...which is why u need to eat 3 times a day to fuel ur body.. Hope that helps...i didnt want to get into the biology of it.

The six basic types of motion are linear motion (straight-line motion), circular motion (rotation along a curve), reciprocating motion (back-and-forth motion), oscillating motion (repetitive swinging motion), vibratory motion (small rapid movements), and random motion (irregular movement in all directions).

First you have to understand that everything gets bigger and smaller when its temperature changes. Maybe you remember seeing someone try to put a metal ball through a metal ring. When the ball and the ring are the same temperature, the ball will not go through the ring. If you then heat up the ring, the ball will go through the ring. This is because the ring gets bigger when heated. Thermometers use this same property to measure the temperature outside. You may have seen that some thermometers have either a red or silver line in them that goes up and down as the temperature changes. Other thermometers use what looks like a spring that is attached to a pionter. That "spring" is actually made from two different metals. Since each metal grows or shrinks differently and since they are attached together, the "spring" bends.

Second, and you probably already know this, is that different things can be bend a long ways before they break and other things can bend very little before they break. Most plastic can be bent a long way, or even bent several times, before it breaks. On the otherhand, glass can only bend a little bit before it breaks.

If the glass is thick enough and the liquid is hot enough, when you pour the liquid into the tumbler the glass on the inside becomes hotter than the glass on the outside. The glass on the inside therfore gets bigger than the glass on the outside. This difference in size caused by the difference in temperature causes the glass to bend, not much, but just enough to break.

Hope that helped.Jeff

An object in motion remains in motion unless acted upon by an unknown force

objects in motion are affected by:

-Gravity

-Friction

-Mass

-Force

-and other objects

Objects in Freefall have a maximum velocity in freefall

an object that is thrown straight up has no velocity during the middle of the time from it takes to toss and hit the ground.

gravity is a constant 9.8m/s

The actual role of the cooling coil behind (or underneath in some cases as well as inside the side walls on some models) is to dissipate the heat collected from INSIDE the refrigerator as a result of the cooling cycle. If you would like more information on the subject, please follow the related links below to "How Stuff Works" The motor typically dissipates heat through a separate heat sink to prevent from excess heat being reintroduced into the refrigerator.

it contains Phosphoric Acid as well as its potassium salts K3PO4, K2HPO4, KH2PO4

The strength of an electromagnet is influenced by factors such as the number of coils in the wire, the amount of current flowing through the wire, the material of the core, and the shape of the electromagnet. Increasing the number of coils, current, and using a core material with high magnetic permeability can increase the strength of an electromagnet.

because they either attract or repel from each other depending on what side is against one side. You can do a lot with magnets for example stick things to the fridge or pick up loose pieces of metal or even shrapnel or broken medal that fell on the floor that you don't want someone to stand on.

They are essential for generating electricity.

In very simple terms, there are two chemicals in a battery - one chemical wants more electrons and the other chemical wants to get rid of electrons. When a path (i.e. circuit) is completed between the two of them (the ends of a typical AA, AAA, D, etc. battery or the two posts on a 9V battery, the electrons are free to move from one post to another. The movement of electrons is current. Different chemicals and/or configurations determine how badly the electrons want to get from one chemical to another. That drive to get from one to another is called voltage potential, and is expressed in volts. How fast the electrons travel between the two chemicals is the flow, or current, and is expressed in Amperes or Amps... for small batteries, it is usually expressed in milliamps because the current is so low. The capacity of the battery is expressed in milliampere-hours which is how many amperes can flow between the chemicals over a given amount of time until the chemicals have exchanged so many electrons that the electrons no longer have any drive to flow between the chemicals anymore.

The principle of a bullet train is based on high-speed rail technology that allows the train to travel at very high speeds by reducing air resistance, using aerodynamic designs, and operating on dedicated tracks. The train is powered by electricity and can reach speeds of over 300 km/h, providing a fast and efficient mode of transportation for passengers.

The friction between the tires and the road surface is what prevents a car from skidding. This friction helps to maintain traction and control between the tires and the road, allowing the driver to steer and brake effectively. Factors such as tire quality, road conditions, and driving speed can all affect the amount of friction available to prevent skidding.

The equivalent international standard for Indian standard IS 513 is EN 10130. Both standards specify the general requirements for cold-rolled low-carbon steel flat products for cold forming, with similar technical parameters and characteristics.

The fraction is always exactly equal to ' 1 ', and so it doesn't
change the value of the quantity that you multiply by it.

Laser tag was invented by George A. Carter III, an American engineer, in 1977. He created a system called "Photon" that used infrared technology for players to tag each other in simulated combat games.

The laser beam in a laser printer is initiated from a laser diode, not a mirror. The laser beam is then directed by a rotating polygon mirror, not an octagonal mirror, which reflects the beam onto the drum surface to create the print image through a process called electrostatic printing.

Trichlorocarbanilide, commonly known as TCC, is an antimicrobial agent used in soaps. However, it has been associated with skin allergies, disruptions in hormonal function, and environmental concerns due to its persistence in water systems. Its long-term effects on human health are still being studied.

Distance measures how far apart two points are in a space, while similarity measures how alike two objects are. In terms of calculation, distance is typically computed using metrics like Euclidean distance, Manhattan distance, or cosine distance. Similarity is often calculated using metrics like cosine similarity, Jaccard similarity, or Pearson correlation.

An input motion refers to the act of providing input or commands to a device, system, or software through physical or digital interactions, such as touching a screen, pressing buttons, or using a keyboard or mouse. It is how users communicate with and control technology to perform tasks or functions.
