Mathematics QUESTION #1307

Question 3162

The D'Alembert solution of the wave equation \(u_{xx}=\dfrac{1}{c^2}u_{tt}\) with \(u(x,0)=f(x)\) and \(u_t(x,0)=g(x)\) is:

\(u(x,t)=\dfrac{f(x+ct)+f(x-ct)}{2}+\dfrac{1}{2c}\int_{x-ct}^{x+ct}g(s)\,ds\)✔️
\(u(x,t)=f(x+ct)+f(x-ct)\)
\(u(x,t)=\dfrac{f(x+ct)-f(x-ct)}{2}+\dfrac{1}{c}\int_0^x g(s)\,ds\)
\(u(x,t)=f(x)g(t)\)

Correct Answer Logic:

D'Alembert's formula gives the general solution of the 1D wave equation: \(u(x,t)=\dfrac{f(x+ct)+f(x-ct)}{2}+\dfrac{1}{2c}\int_{x-ct}^{x+ct}g(s)\,ds\). It represents two travelling waves moving in opposite directions.

Question 3167

In RC beam shear design per ACI 318 (simplified), the nominal concrete shear strength \(V_c\) for a rectangular beam with \(f'_c\) in MPa, \(b_w\) in mm, and \(d\) in mm is:

\(V_c = 0.33 \lambda \sqrt{f'_c} \cdot b_w \cdot d\) (N)
\(V_c = 0.17 \lambda \sqrt{f'_c} \cdot b_w \cdot d\) (N)✔️
\(V_c = 0.17 \lambda f'_c \cdot b_w \cdot d\) (N)
\(V_c = \lambda \sqrt{f'_c} \cdot b_w \cdot d\) (N)

Correct Answer Logic:

Per ACI 318 simplified equation: \(V_c = 0.17\lambda\sqrt{f'_c} \cdot b_w \cdot d\) (in Newtons, SI units). For normal weight concrete \(\lambda = 1.0\). The more detailed equation also accounts for \(N_u\), reinforcement ratio, and moment. The factor 0.33 applies in the more conservative detailed method for certain conditions.

Agronomy QUESTION #2100

Question 3179

Biological nitrogen fixation (BNF) by soybean-Bradyrhizobium japonicum symbiosis requires which essential micronutrient as a component of the nitrogenase enzyme complex?

Zinc (Zn) — as a cofactor for auxin-mediated nodule initiation
Molybdenum (Mo) — as a component of the iron-molybdenum cofactor (FeMo-co) at the active site of nitrogenase that reduces \(N_2\) to \(NH_3\)✔️
Boron (B) — for nodule cell wall synthesis and longevity
Copper (Cu) — for leghemoglobin synthesis in nodule cortex

Correct Answer Logic:

Nitrogenase consists of two proteins: dinitrogenase (MoFe protein) containing the FeMo-co active site where \(N_2\) is reduced (\(N_2 + 8H^+ + 8e^- + 16ATP \rightarrow 2NH_3 + H_2 + 16ADP + 16P_i\)), and dinitrogenase reductase (Fe protein). Mo is irreplaceable at the active site — Mo deficiency severely impairs BNF. Fe is also essential (leghemoglobin, Fe-S clusters). Both Mo and Fe are required for full BNF activity.
