In electrical circuit, this arrangement is called a R-L series circuit. It is a circuit containing elements of an inductor (L) and a resistor (R). Inductance is expressed in units of Henry while resistance is expressed in units of ohms. The relationship between these values is called the impedance, denoted as Z. Its equation is
Z = √(R^2 + L^2)
Z = √((1.24×10^3 ohms)^2 + (6.95×10^-6 H)^2)
Z = 1,240 ohms
The unit for impedance is also ohms. Since the circuit is in series, the voltage across the inductor and the resistor are additive which is equal to 12 V. Knowing the impedance and the voltage, we can determine the maximum current.
I = V/Z=12/1,240 = 9.68 mA
But since we only want to reach 73.6% of its value, I = 9.68*0.736 = 7.12 mA. Then, the equation for R-L circuits is
, where τ = L/R = 6.95×10^-6/1.24×10^3 = 5.6 x 10^-9
Then,
t = 7.45 nanoseconds
Part B.) If t = 1.00τ, then t/τ = 1. Therefore,
I = 6.12 mA

Explanation:
The momentum of an object is given by the equation:
where
m is the mass of the object
v is the velocity
Since velocity is a vector, it follows that momentum is a vector as well, therefore it has a magnitude and a direction (the same as the velocity).
The SI unit of the momentum is
An important law related to the momentum is the law of conservation of momentum, which states that for an isolated system (= zero net external force on it), the total momentum of the system is conserved.
