linear momentum
Step 1: Kirchhoff’s junction rule (also known as the current law) states that the total current entering a junction equals the total current leaving the junction.
Step 2: This law is derived from the principle of conservation of charge, ensuring that no charge is lost or created at the junction.
Step 3: Therefore, Kirchhoff's junction rule is based on the conservation of charge.
A quantity \( X \) is given by: \[ X = \frac{\epsilon_0 L \Delta V}{\Delta t} \] where:
- \( \epsilon_0 \) is the permittivity of free space,
- \( L \) is the length,
- \( \Delta V \) is the potential difference,
- \( \Delta t \) is the time interval.
The dimension of \( X \) is the same as that of:
The expression given below shows the variation of velocity \( v \) with time \( t \): \[ v = \frac{At^2 + Bt}{C + t} \] The dimension of \( A \), \( B \), and \( C \) is:
