Ariel reconnaissance using manned balloons was one way of keeping tabs on the enemy. The balloonists sent messages to the ground via semaphore (flag signals) or in some cases by telegraph. One of the first effective uses of the balloon was at Fortress Monroe, Virginia on July 31st, 1861 and again on August 1st, 1861. The August 1st flight featured the first 'aircraft carrier' when a balloon was tied off to a transport ship in Chesapeake Bay.

Civil War field hospitals were tents on the battle ground used to treat people. They could also be converted from homes, barns and any other buildings.
Vernon Jordan Jr. was a civil rights leader. He was the field secretary for the NAACP in Georgia.
Carmen Velasquez is a civil court judge in New York.
No, neither the field, battle, nor the generals shown are real - it is all a fiction...
The first method of conducting field surveillance was likely through human observation, where individuals would physically monitor and watch over a specific area for any activities of interest or potential threats. This method has evolved over time with advancements in technology, such as the use of cameras, drones, and other surveillance equipment to enhance monitoring capabilities.
For a physicist, conducting controlled experiments and analyzing data would be the best method to demonstrate their concepts. For a biologist, conducting field studies and experiments on living organisms would be ideal. For a psychologist, conducting experiments, surveys, and observational studies to gather data on human behavior would be the method of choice.

Inside a conducting hemisphere shell, the electric field is zero because the charges redistribute themselves to cancel out any electric field. Outside the conducting hemisphere shell, the electric field behaves as if all the charge is concentrated at the center of the hemisphere.
In a conducting sheet, the electric field is zero inside the material but can exist on the surface due to excess charge redistribution. In a non-conducting sheet, the electric field can exist both inside the material and on the surface, depending on the charge distribution.
The behavior of a magnetic field inside a conducting cylinder is such that the field lines run parallel to the axis of the cylinder. This is due to the induced currents in the cylinder that create a magnetic field that opposes the external magnetic field.

electric field inside the conducting sphere is ZER0..! because their are equivalent charges all around the sphere which makes the net force zero hence we can say that the electric field is also zero.!
the constitutes an electromagnetostatic field are static electric and magnetic fields in conducting medium.
Conducting spheres allow for the flow of electric charge, while non-conducting spheres do not. Conducting spheres can redistribute charge in response to an external electric field, while non-conducting spheres cannot. Conducting spheres are typically made of metals, while non-conducting spheres are typically made of insulating materials.
The charge distribution on a conducting shell affects the electric field inside the shell. If the charge is distributed evenly, the electric field inside the shell is zero. If the charge is not evenly distributed, there will be an electric field inside the shell.
The relationship between the magnetic field and current in a conducting wire is described by Ampre's law, which states that a current flowing through a wire creates a magnetic field around it. The strength of the magnetic field is directly proportional to the current flowing through the wire.
