Mathematics QUESTION #1320

Question 3345

If two vectors $\vec{a}$ and $\vec{b}$ satisfy $\vec{a}\times\vec{b}=\vec{0}$ and $\vec{a}\neq\vec{0}$, $\vec{b}\neq\vec{0}$, then:

They are perpendicular
They are parallel✔️
Their magnitudes are equal
Their dot product is zero

Correct Answer Logic:

The cross product $\vec{a}\times\vec{b}=|\vec{a}||\vec{b}|\sin\theta\,\hat{n}$. If $\vec{a}\times\vec{b}=\vec{0}$ and neither vector is zero, then $\sin\theta=0\Rightarrow\theta=0$ or $\pi$, meaning the vectors are parallel (or anti-parallel).

Dairy Food Science and Technology QUESTION #5965

Question 3350

The primary purpose of 'aging' ice cream mix overnight at $2\text{–}4^{\circ}\text{C}$ before freezing is:

To allow lactose crystallization to reach equilibrium
To allow complete fat crystallization, protein hydration, and emulsifier-protein interaction, improving whipping properties and texture✔️
To allow starter culture to acidify the mix
To reduce microbial contamination

Correct Answer Logic:

Aging (maturation) of ice cream mix at $2\text{–}4^{\circ}\text{C}$ for $4\text{–}24$ hours serves: (1) fat crystallization (partially crystalline fat globules enable partial coalescence during freezing); (2) protein hydration (improved viscosity and body); (3) emulsifier adsorption to fat globule surface enabling controlled partial coalescence.

Mathematics QUESTION #1278

Question 3360

If a homomorphism $\varphi: G\to H$ is injective, then:

Every element of H has a preimage in G
$\ker\varphi$ is trivial (contains only identity)✔️
G and H have the same order
$\varphi$ must also be surjective

Correct Answer Logic:

An injective (one-to-one) homomorphism has trivial kernel: if $\varphi(g)=e_H$ then $\varphi(g)=\varphi(e_G)$, and by injectivity $g=e_G$. So $\ker\varphi=\{e_G\}$. This is both a necessary and sufficient condition for injectivity of a group homomorphism.
