Physics QUESTION #1055

Question 2747

A wire of resistance $R$ is cut into 8 equal pieces. Four pieces in parallel form one equivalent resistance, and two such sets in series. Net effective resistance:

$\dfrac{R}{16}$
$\dfrac{R}{8}$
$\dfrac{R}{64}$
$\dfrac{R}{32}$✔️

Correct Answer Logic:

Each piece has resistance $R/8$. Four in parallel: $R_p = \frac{R/8}{4} = \frac{R}{32}$. Two such sets in series: $R_{total} = 2\times\frac{R}{32} = \frac{R}{16}$. Wait: $\frac{R/8}{4}=\frac{R}{32}$, then $2\times\frac{R}{32}=\frac{R}{16}$. So answer is $R/16$ = option (1). Re-check: each piece $=R/8$, 4 in parallel $=\frac{R/8}{4}=\frac{R}{32}$, 2 in series $=\frac{2R}{32}=\frac{R}{16}$. Answer: option (1) = $R/16$.

Verbal Reasoning QUESTION #8156

Question 2758

Given that $0 < x < y < 1$, compare the two quantities:

Quantity A: $1 - y$

Quantity B: $y - x$

Quantity A is greater
Quantity B is greater
The two quantities are equal
The relationship cannot be determined from the information given✔️

Correct Answer Logic:

We know $0 < x < y < 1$. Let's test specific values to see if the relationship is fixed.

Example 1: $x = 0.1,\ y = 0.2$.
Quantity A: $1 - 0.2 = 0.8$. Quantity B: $0.2 - 0.1 = 0.1$. A > B.

Example 2: $x = 0.1,\ y = 0.9$.
Quantity A: $1 - 0.9 = 0.1$. Quantity B: $0.9 - 0.1 = 0.8$. B > A.

Since the relationship changes depending on the values of $x$ and $y$, it cannot be determined from the information given.
