Verified Correct Answer: Option A
Physical Principles & Numerical Solution
First, the two 2-ohm resistors are in parallel
R\(_T\) = \(\frac{2 \times 2}{2 + 2}\) = 1 ohm
Now, the 3, 4, and 1 ohm resistors are in series
Therefore, R\(_eq\) = 3 + 4 + 1 = 8 ohms.

Solution
The linear expansivity of brass is 2 x 10\(^{-5}\) C\(^{-1}\). If the volume of a piece of brass is 15.00cm at 0^\circC, what is the volume at 100^\circC
A
16.03cm\(^3\)
B
15.09cm\(^3\)
C
16.00cm\(^3\)
D
15.03cm\(^3\)
medium Difficulty
Verified Correct Answer: Option B
Physical Principles & Numerical Solution
Volume Expansivity \(\gamma\) = \(3\alpha\)
\(\gamma = 3 \times 2\times10^{-5}\)
\(\gamma = 6\times10^{-5}C^{-1}\)
\(V_{2} = V_{1}(1 + \gamma\theta)\)
\(V_{2} = 15( 1 + (6\times10^{-5}\times(100-0)))\)
\(V_{2} = 15(1.006)\)
= \(15.09cm^{3}\)

Solution
A lead bullet of mass 0.05 kg is fired with a velocity of 200 m/s into a lead block of mass 0.95 kg. Given that the lead block can move freely, the final kinetic energy after impact is
A
100J
B
150J
C
50J
D
200J
medium Difficulty
Verified Correct Answer: Option C
Physical Principles & Numerical Solution
From the law of conservation of linear momentum,
\(m_1 u_1 + m_2 u_2 = m_1 v_1 + m_2 v_2\)
Since the collision is inelastic, we have
\((0.05 \times 200) - (0.95 \times 0) = (0.05 + 0.95)V\)
\(10 = V\)
\(V = 10ms^{-1}\)
Hence the Kinetic energy = \(\frac{1}{2} (0.05 + 0.95) \times 10^2\)
= \(\frac{1}{2} \times 100\)
= 50J
