how does negative feedback influence the behavior of a system .
Negative feedback is a process by which a system responds to a change in its output by counteracting that change, which helps to maintain the stability of the system.
How to explain the informationThis feedback mechanism is used in many different systems, from biological organisms to technological systems.
In a negative feedback loop, the output of the system is measured, and this measurement is compared to a desired or setpoint value. If the output deviates from the setpoint, the feedback mechanism initiates a corrective action to bring the output back to the setpoint value. This corrective action can be either reducing the input to the system, or increasing it.

1. Of the following answers, which is NOT a method to control dangerous welding processes?
Purge gas damming systems Glove boxes/bags Fume-less electrodes Backing plates
Answer:
The correct option is;
Purge gas d a m m i n g systems
Explanation:
The hazards that can occur during a welding process includes exposure to molten metal, hot s l a g, flying sparks, ultraviolet light, skin burns from chemicals, inhalation of toxic fumes, fire outbreak, and electric shocks
The purge gas is meant to protect the weld pool from contamination by other reactive gases, such as oxygen and steam, while the weld zone is still molten or very hot. It does not protect the welder from the produced poisonous fumes
Purge gas d a m m i ng systems, are used to reduce the amount of gas used for purging during welding so as to reduce the cost of the consumable inert gas used for welding and the time for welding.
Glove boxes or bags can be used to protect the welder from welding hazards by completely enclosing the work area and holding the poisonous fumes within the enclosure, away from the welder
Fume-less electrodes are electrodes that produce lesser amount of fumes compared to the generally available electrode of similar specification
Backing plates can provide support to hot molten weld metal during welding processes such as e l e c t r o s l a g welding
Answer: Fume-less electrodes
Explanation: I am currently doing dual credits so I have welding classes. Based off my experience, having electrodes that are scentless is risky, because the electrodes can produce harmful chemical too, which therefore you cannot feel until the damage is already done.

A shorter product life
B harm to an ecosystem
C increase in human diseases
D reduced workplace safety
Answer:
its b
Explanation:
The option that is a potential environmental risk of adopting a new technology is harm to an ecosystem. The correct option is B.
What is technology?Technology is the implementation of knowledge of science to the feasible goals of human life, or, as it is frequently referred to, to the modification and deception of the human environment.
The majority of electronics contain non-biodegradable materials, as well as heavy metals and toxic materials such as cadmium, lead, and mercury.
These toxic materials can leach into the ground over time, contaminating the water we drink, the plants we eat, and the animals that live nearby.
Pollution, radiation, noise, land use patterns, the work environment, and climate change are all examples of environmental health risks.
Policies in sectors other than health, such as energy, industry, agriculture, transportation, and land planning, are driving these risks.
Thus, the correct option is B.

B.high gauge pressure
C.inoperative compressor
D.no compressor cycling
Answer:
I believe 80% the answer is low gage pressure.
Explanation:
while naturally a restriction of an orifice like placing your thumb on a water hose would cause a high pressure output, however in an entire system if the proper amount of fluid is not making its way through the system then there would be inadequate system pressure.
