Answer:
Adiabatic
Explanation:
An adiabatic process is a thermodynamic process in which the system does not exchange heat with its surroundings. An adiabatic process may also be isentropic, meaning that the process may be reversible. The term adiabatic refers to elements that prevent heat transfer with the environment. An insulated wall is quite close to an adiabatic boundary. Hence the term of the adiabatic wall appears.
Air is a bad thermal conductor, this means that air is a system that makes it difficult to change the temperature with the systems around it, so we can conclude that the above question deals with the thermodynamic process called adiabatic.
Answer:
The magnitude of the net electric field is 
Explanation:
Given that,
Charge density 
Charge density 
Distance 
Distance 
We need to calculate the magnitude of the net electric field
Using formula of electric field
Put the value into the formula
Hence, The magnitude of the net electric field is
The radius of the cylinder is equal to half the diameter:
The volume of the cylinder is given by:
where h is the heigth of the cylinder. Converting into meters,
And the density of the material will be given by the ratio between the mass and the volume:
