Ensuring that all students achieve the same level of athletic performance

Correct Answer Logic:

Dualism separates the mind and body; physical educators often struggle to prove that 'bodily' training has 'intellectual' or educational value in such a framework.

Chemistry QUESTION #7388

Question 2408

Ionic radii are:

Directly proportional to square of effective nuclear charge
Inversely proportional to effective nuclear charge✔️
Inversely proportional to square of effective nuclear charge
Directly proportional to effective nuclear charge

Correct Answer Logic:

Effective nuclear charge (Z*) and ionic size:
As Z* increases, the nucleus pulls the electron cloud more strongly inward, decreasing the ionic radius. So ionic radius $\propto \dfrac{1}{Z^*}$ — i.e., inversely proportional to effective nuclear charge.

This explains trends: across a period, Z* increases, so ionic (and atomic) radii decrease.

Question 2409

Gulabjamun dough uses which leavening agent to achieve a porous texture during deep frying?

Baking soda (sodium bicarbonate, $\text{NaHCO}_3$)
Baking powder or a mixture of baking soda and maida (refined flour)✔️

deliberate✔️
determined
dissident
desperate

Correct Answer Logic:

PRECIPITATE (as an adjective) means acting hastily without careful thought — rash or impulsive. Its antonym is deliberate, which means done carefully and intentionally with full consideration. 'Determined' means resolute. 'Dissident' means disagreeing. 'Desperate' means in despair. Only 'deliberate' directly opposes the rushed, unthinking nature of 'precipitate.'

Electrical Engineering QUESTION #2183

Question 2412

In AM with modulation index $\mu = 0.5$, the efficiency (ratio of useful sideband power to total transmitted power) is:

$11.1\%$✔️
$25.0\%$
$33.3\%$
$20.0\%$

Correct Answer Logic:

$\eta = \frac{\mu^2/2}{1+\mu^2/2}\times100 = \frac{0.125}{1.125}\times100 \approx 11.1\%$. At $\mu=1$ (100% modulation), efficiency peaks at only $33.3\%$, illustrating DSB-FC inefficiency.

Which type of evidence sampling technique involves examining 100 percent of available items?

Attribute
Stop-and-go

Mathematics QUESTION #6009

Question 2419

Let $f:[0,1]\to\mathbb{R}$ satisfy $f(xy)=f(x)\cdot f(y)$ for all $x,y\in[0,1]$ with $f(0)\neq 0$. If $y=y(x)$ solves $\dfrac{dy}{dx} = f(x)$ with $y(0)=1$, find $y\!\left(\dfrac{1}{4}\right)+y\!\left(\dfrac{3}{4}\right)$.

3✔️
4
2
5

Correct Answer Logic:

From the functional equation $f(xy)=f(x)f(y)$ with $f(0)\neq 0$, putting $x=y=0$ gives $f(0)=f(0)^2 \Rightarrow f(0)=1$. Putting $y=0$: $f(0)=f(x)f(0) \Rightarrow f(x)=1$ for all $x$.

So $\frac{dy}{dx}=1$, giving $y=x+C$. With $y(0)=1$: $C=1$, so $y=x+1$.

$y(1/4)+y(3/4)=(1/4+1)+(3/4+1)=5/4+7/4=12/4=\mathbf{3}$
