Q1. Which equation correctly relates kinetic energy to mass and speed?
A. Ek = mv
B. Ek = 1/2 mv
C. Ek = 1/2 mv^2
D. Ek = mv^2
Show answer & explanation
✓ Answer: C. Ek = 1/2 mv^2
Kinetic energy is calculated using Ek = 1/2 mv^2, where m is mass in kg and v is speed in m/s. Doubling the speed quadruples the kinetic energy because speed is squared, not just doubled as the mv^2 option might suggest.
Q2. Two identical resistors of 6 Ω each are connected in parallel. What is their combined resistance?
A. 12 Ω
B. 6 Ω
C. 3 Ω
D. 0.33 Ω
Show answer & explanation
✓ Answer: C. 3 Ω
For two equal resistors in parallel, the combined resistance is half of one resistor's value, so 6 Ω / 2 = 3 Ω. Adding them to get 12 Ω is what happens in series, not parallel.
Q3. The specific latent heat of fusion of ice is 334,000 J/kg. How much energy is needed to melt 0.5 kg of ice at 0°C with no temperature change?
A. 167,000 J
B. 668,000 J
C. 334,000 J
D. 83,500 J
Show answer & explanation
✓ Answer: A. 167,000 J
Using energy = mass × specific latent heat: 0.5 × 334,000 = 167,000 J. This energy changes the state of the ice without raising its temperature, since all the energy goes into breaking intermolecular bonds during melting.
