The voltage across all the resistors is the same i.e 120V
Each element of the parallel circuit has the same voltage applied to it. The total current flowing from the source is equal to the sum of the currents across each path. The electric potential difference (V) across each resistor in a parallel circuit is the same. Ohm's law states that I = V / R applies to the current in a resistor. The current will be lowest where the resistance is highest since the V is the same for each resistor. The currents passing through each resistor in a parallel combination have the same voltage across them because of their different resistance values and the laws of Ohms i., If two or more components are connected in parallel, they will be having same difference of potential (voltage) across their ends Parallel circuits are then used as current dividers.

Answer:
Energy of scattered photon is 232.27 keV.
Kinetic energy of recoil electron is 497.73 keV.
The recoil angle of electron is 13.40°
Explanation:
The energy of scattered photon is given by the relation :
.....(1)
Here E₁ is the energy of incident photon, E₂ is the energy of scattered photon,
is mass of electron and θ is scattered angle.
Substitute 730 keV for E₁, 511 keV for
and 120° for θ in equation (1).
![E_{2}=\frac{730 }{1+(\frac{730 }{511 })(1-\cos120) }](https://tex.z-dn.net/?f=E_%7B2%7D%3D%5Cfrac%7B730%20%7D%7B1%2B%28%5Cfrac%7B730%20%7D%7B511%20%20%7D%29%281-%5Ccos120%29%20%7D)
E₂ = 232.27 keV
Kinetic energy of recoil electron is given by the relation :
K.E. = E₁ - E₂ = (730 - 232.27 ) keV = 497.73 keV
The recoil angle of electron is given by :
![\cot\phi=(1+\frac{E_{1} }{m_{e}c^{2} })\tan\frac{\theta}{2}](https://tex.z-dn.net/?f=%5Ccot%5Cphi%3D%281%2B%5Cfrac%7BE_%7B1%7D%20%7D%7Bm_%7Be%7Dc%5E%7B2%7D%20%20%7D%29%5Ctan%5Cfrac%7B%5Ctheta%7D%7B2%7D)
Substitute the suitable values in above equation.
![\cot\phi=(1+\frac{730 }{511 })\tan\frac{120}{2}](https://tex.z-dn.net/?f=%5Ccot%5Cphi%3D%281%2B%5Cfrac%7B730%20%7D%7B511%20%20%7D%29%5Ctan%5Cfrac%7B120%7D%7B2%7D)
![\cot\phi=4.20](https://tex.z-dn.net/?f=%5Ccot%5Cphi%3D4.20)
= 13.40°

A code of ethics is a set of principles and rules used by individuals and organizations to govern their decision making process, as well as to distinguish right from wrong. These codes are often more complex and contextual than simple morality, acknowledging specific situations and providing guidance. Many codes of ethics also specify penalties for violations. Professional and personal codes of ethics ensure that adherents are behaving in a socially acceptable manner. Organizations with an established code of ethics usually have review processes and appeal procedures in place to guard against malicious or self-serving use of the code.
