Chemistry QUESTION #7355

Question 4045

The total number of atomic orbitals present in the fourth principal energy level ($n = 4$) of an atom is:

8
16✔️
32
4

Correct Answer Logic:

Formula: Total orbitals in shell $n$ = $n^2$

For $n = 4$: $4^2 = 16$ orbitals

Breakdown:

4s: 1 orbital
4p: 3 orbitals
4d: 5 orbitals
4f: 7 orbitals
Total = 1+3+5+7 = 16

Civil Engineering QUESTION #6611

Question 4049

Which of the following is true for the 'Shear Lag' effect in tension members?

It only occurs in circular solid bars.
It accounts for the non-uniform stress distribution when not all elements of a cross-section are connected.✔️
It increases the effective net area ($A_e$) to be larger than the gross area ($A_g$).
It is neglected in LRFD design.

Correct Answer Logic:

Shear lag occurs when the tensile load is transmitted by some but not all of the cross-sectional elements (e.g., only one leg of an angle connected). The reduction factor $U$ is used to calculate effective area: $A_e = A_n U$.

Question 4053

Zero-based budgeting (ZBB) requires managers to:

Justify only incremental changes in budgeted amounts.
Prepare budgets based on historical costs.
Justify all budgeted expenditures from scratch.✔️
Ignore past costs entirely.

Correct Answer Logic:

Zero-based budgeting (ZBB) requires that every budget item be re-evaluated and justified from zero each budget period, regardless of previous spending. Managers must build their budget from scratch by justifying all proposed expenditures, not just changes from the prior year. This contrasts with incremental budgeting which adjusts last year's figures.

Physics QUESTION #1042

Question 4059

To an AC supply of 220 V at 50 Hz: $R=20\ \Omega$, capacitive reactance $X_C=25\ \Omega$, inductive reactance $X_L=45\ \Omega$. Current and phase angle are:

15.6 A and 30°
15.6 A and 45°
7.8 A and 30°
7.8 A and 45°✔️

Correct Answer Logic:

Impedance: $Z=\sqrt{R^2+(X_L-X_C)^2}=\sqrt{400+(45-25)^2}=\sqrt{400+400}=\sqrt{800}=20\sqrt{2}\ \Omega$. Current $=\frac{220}{20\sqrt{2}}=\frac{220}{28.28}\approx7.78\ \text{A}\approx7.8\ \text{A}$. Phase angle: $\tan\phi=\frac{X_L-X_C}{R}=\frac{20}{20}=1\Rightarrow\phi=45°$.
