Which statement correctly distinguishes 'sweet whey' from 'acid whey'?

Sweet whey has higher fat content; acid whey has lower fat
Sweet whey ($\text{pH}\;5.9\text{–}6.3$) comes from rennet-coagulated cheese; acid whey ($\text{pH} < 5$) comes from acid-coagulated products like cottage cheese or paneer✔️

Chemistry QUESTION #1095

Question 4157

Energy and radius of first Bohr orbit of He$^+$ and Li$^{2+}$ are: [Given: $R_H = 2.18\times10^{-18}\ \text{J}$, $a_0=52.9\ \text{pm}$]

$E_n(\text{Li}^{2+})=-19.62\times10^{-16}\ \text{J}$; $r_n(\text{Li}^{2+})=17.6\ \text{pm}$; $E_n(\text{He}^+)=-8.72\times10^{-16}\ \text{J}$; $r_n(\text{He}^+)=26.4\ \text{pm}$
$E_n(\text{Li}^{2+})=-8.72\times10^{-16}\ \text{J}$; $r_n(\text{Li}^{2+})=17.6\ \text{pm}$; $E_n(\text{He}^+)=-19.62\times10^{-16}\ \text{J}$; $r_n(\text{He}^+)=17.6\ \text{pm}$
$E_n(\text{Li}^{2+})=-19.62\times10^{-18}\ \text{J}$; $r_n(\text{Li}^{2+})=17.6\ \text{pm}$; $E_n(\text{He}^+)=-8.72\times10^{-18}\ \text{J}$; $r_n(\text{He}^+)=26.4\ \text{pm}$✔️
$E_n(\text{Li}^{2+})=-8.72\times10^{-18}\ \text{J}$; $r_n(\text{Li}^{2+})=26.4\ \text{pm}$; $E_n(\text{He}^+)=-19.62\times10^{-18}\ \text{J}$; $r_n(\text{He}^+)=17.6\ \text{pm}$

Correct Answer Logic:

$E_n = -Z^2 R_H/n^2$. For Li$^{2+}$ ($Z=3, n=1$): $E=-9\times2.18\times10^{-18}=-19.62\times10^{-18}\ \text{J}$. For He$^+$ ($Z=2, n=1$): $E=-4\times2.18\times10^{-18}=-8.72\times10^{-18}\ \text{J}$. Radii: $r=a_0 n^2/Z$. Li$^{2+}$: $r=52.9/3=17.6\ \text{pm}$. He$^+$: $r=52.9/2=26.45\approx26.4\ \text{pm}$. Correct: option (3).

Mathematics QUESTION #6003

Question 4160

A manufacturing firm currently produces 2000 items. The rate of change of production $P$ with respect to additional workers $x$ is given by $\frac{dP}{dx} = 100 - 12\sqrt{x}$. If the firm hires 25 additional workers, what will be the new level of production?

2500
3000
3500✔️
4500

Correct Answer Logic:

We integrate $\frac{dP}{dx} = 100 - 12\sqrt{x}$ from $x = 0$ to $x = 25$:

$P = \int_0^{25}(100 - 12\sqrt{x})\,dx = \left[100x - 12 \cdot \frac{2}{3}x^{3/2}\right]_0^{25}$

$= \left[100x - 8x^{3/2}\right]_0^{25} = 100(25) - 8(25)^{3/2} = 2500 - 8(125) = 2500 - 1000 = 1500$

New production $= 2000 + 1500 = \mathbf{3500}$
