Research the use in the military of magnetic anomaly detectors, mads. write a brief 300-word essay answer the following questions on mads. what is the main idea behind mads? what can be detected by using mads? a brief history of the mad development.
Answer:
MADs are Magnetic Anomaly Detectors and the main idea behind MADs is that they follow the principle rule that objects with metallic properties get in the way of the magnetic lines of the Earth's forces. Metallic things such as submarines are normally detected using MADs. MAD development started around 1917. The function of the MADs was to identify anomalies in the Earth’s magnetic field that were caused by submarines. Later on, around 1941 in the US and Britain, there was a development of magnetic detection devices. These were meant to measure Earth’s magnetic field. So ultimately after this in 1943, MADs were now installed in ASW aircrafts. However, due to its limited range and its incapacity to detect the magnetic variances of different sources, MADs started to be used along with sonobuoys which was the opposite of what they were intended to be used for.
Explanation:
The primary concept underlying MADs, which stand for Magnetic Anomaly Detectors, is that they adhere to the general notion that things with metallic qualities obstruct the magnetic lines of the Earth's forces.
What is Magnetic Development?MADs are used to find metallic objects, like submarines. Around 1917, MAD development first began.
The purpose of the MADs was to locate submarine-related magnetic anomalies in the Earth's magnetic field. Later, about 1941, magnetic detecting technology developed in the US and Great Britain.
These were designed to gauge the magnetic field of the planet. As a result, MADs were eventually deployed in ASW aircraft in 1943. However, MADs have a restricted range and are unable to detect the magnetic variations of many sources.
Therefore, The primary concept underlying MADs, which stand for Magnetic Anomaly Detectors, is that they adhere to the general notion that things with metallic qualities obstruct the magnetic lines of the Earth's forces.

The increase in pressure, with volume constant will increase the temperature. The increase in volume, with pressure constant will increase the temperature. The increase in pressure, with temperature constant will decrease the volume.
What are pressure, temperature and volume?These three are the characteristics of a gas. A gas is always in some pressure, having some volume and temperature.
According to the ideal gas law,
pV =nRT
Here, p is the pressure, V is the volume, n is number of moles, R is the universal gas constant and T is the temperature.
The volume of a gas is directly proportional to its absolute temperature when pressure is constant, according to Charles's law.
The volume of a gas is inversely proportional to its pressure when temperature is constant according to the Boyle's law.
