Explanation:
Answer:
Thermodynamics is usually defined as a branch of physics that deals with the study of the heat and various form of energy, and their interaction between the.
The first law says that heat appears as energy, and it cannot be produced and also cannot be demolished. It can only change from one form to another. This signifies that the total amount of energy present in the universe remains constant.
This first law can be mathematically represented as:
ΔU = Q - W
where ΔU = Changes occurring in the internal energy
Q = amount of heat added to the system
W = Amount of work done by the system
Answer:
E = {(Charge Density/2e0)*(1 - [z/(sqrt(z^2 - R^2))]}
R is radius = Diameter/2 = 0.210m.
At z = 0.2m,
Put z = 0.2m, and charge density = 2.92 x 10^-2C/m2, and constant value e0 in the equation,
E can be calculated at distance 0.2m away from the centre of the disk.
Put z = 0.3m and all other values in the equation,
E can be calculated at distance 0.3m away from the centre of the disk
