"Fateful" decision means a significant decision with serious and often negative consequences. In this context, "disastrous" is synonymous to "fateful," because it means that it is a decision that led to an unfavourable outcome for the company.

Superficial means: On the surface Not deep Affecting only the outer layer So, a superficial wound is a wound that affects only the surface of the body — that is, an external wound.

Fizzled out means to gradually end, often in a disappointing or weak way.

The word vehement means showing strong feeling, force or intensity, especially in expressing opinions or character. A person of vehement character is therefore forceful, intense, and insistent.

Average life = \(\frac{1}{\text{decay constant}}\) Average life = \(\frac{1}{1.0 \times 10^{-7}}\) = 1. 0 x 10\(^{-7}\)

Current (I) in the circuit = V/Z But z = \sqrt R2 + (XL - XC)2 = \sqrt 82 + (16 – 10) 2 = \sqrt 64 + 36 = \sqrt 100 = 10Ω ∴ Current (I) = V/Z = 12/10 = 1.2 A

The temperature coefficient of resistance is given by \alpha = \(\frac{\text{Increase in resistance per ºC rise in temp}}{\text{resistance at 0ºC}}\) And for metals where resistance increases with temperature rise, the temperature coefficient of resistance is positive; on the other hand, in semiconductors, where resistance decreases with temperature rise, the temperature coefficient of resistance is negative.

The sensitivity of a measuring instrument is given by deflection per unit current: and given that deflection = 30º; and current (I) = 3A: then the sensitivity of the meter = 30/3 = 10.0

I wave - particle duality of matter, the momentum of sub-atomic particle is given by P = h/\lambda where h = planck constant ; \lambda = wave length => \lambda = h/P

In a reverse biased junction diode only a very small current flows in, carried by the minority carriers which are the negative charges in the n-semi conductor

In an R - L - C circuit resonance occurs when the inductive reactance (XL), is equal to the capacitive reactance (XC) 1.e XL = XC

The binding energy of a nucleus is the work done or energy needed to separate the nucleons (protons and neutrons) apart. Again, experiment shows that the total mass of all individual nucleons is greater than that of the nucleus in which they are together. This difference in mass is the measure of the binding energy of the particular nucleus. For helium\(^4_2\)He It has 4 nucleons, 2 protons and 2 neutrons 2:H = 2 x 1.00783 = 2.01566 2:n = 2 x 1.00867 = 2.01734 ∴ 2:H + 2:n = 4.03300u But the helium nucleus has a mass of 4.00260u ∴ Binding energy = difference between nucleons and nucleus = 4.03300U - 4.00260U = 0.03040U
