Question 2

What happens if a RC beam is 'Over-reinforced'?

The steel yields before the concrete crushes
The concrete crushes before the steel yields✔️
The beam will never fail
The deflection will be very large before failure

Correct Answer Logic:

An over-reinforced beam fails suddenly (brittle failure) because the concrete reaches its compressive limit while the steel is still in the elastic range.

Question 7

J Limited makes furniture with a mark-up of 40%. A job 10 km away involves: Materials $400; Labour $240; Travel $2 per km each part of journey. What price will the company quote?

$916
$924
$936
$952✔️

Correct Answer Logic:

Option D ($952) is correct.

Travel = 10 km each way = 20 km × $2 = $40

Total cost = $400 + $240 + $40 = $680

Quoted price = $680 × 1.40 = $952

Chemistry QUESTION #73

Question 11 (Select all that apply)

Which of the following best explains why phenol reacts with aqueous NaOH, but alcohols do not?

Phenol is weakly acidic due to resonance stabilization of phenoxide ion.✔️
Phenol form hydrogen bonding that facilitates ionization.
Alcohols contain a strong O-H bond that cannot be broken by weak bases.
Phenol has a lower boiling point than alcohol.

Correct Answer Logic:

Phenol is about a million times more acidic than alcohol because the resonance stabilization of the phenoxide ion lowers the energy of the product, favoring the reaction with NaOH.

$A + 20$

Correct Answer Logic:

Old average = $\frac{5+10+15}{3} = 10$. New average = $\frac{5+10+15+20}{4} = \frac{50}{4} = 12.5$

Chemistry QUESTION #7380

Question 15

Which of the following is a WRONG statement?

The uncertainty principle is $\Delta E \cdot \Delta t \geq \dfrac{h}{4\pi}$
Half-filled and fully filled orbitals are more stable due to exchange energy, symmetry, and balanced electron arrangement
In hydrogen-like atoms, the energy of the 2s orbital is less than that of 2p orbital✔️
de Broglie wavelength is $\lambda = \dfrac{h}{mv}$ where $v$ is the group velocity of the particle

Correct Answer Logic:

Analysis of option (3):
In hydrogen and hydrogen-like (one-electron) atoms, orbitals with the same $n$ are degenerate — 2s and 2p have the same energy (energy depends only on $n$). The statement that 2s energy is less than 2p is only true for multi-electron atoms (due to penetration and shielding). Hence option (3) is wrong for hydrogen-like atoms.
