A 1000 W heater is used for 2 hours. Energy consumed in kWh is MCQ with Answer and Explanation

A 1000 W heater is used for 2 hours. Energy consumed in kWh is
A. 1000 kWh
B. 2 kWh
C. 0.5 kWh
D. 2000 kWh
Answer: Option B
Solution (By JKSSB Mock Tests)
Power = 1 kW (1000 W). Time = 2 h. Energy = Power × time = 1 × 2 = 2 kWh. 1 kWh = 3.6 × 10⁶ J, but here answer in kWh. Commercial unit.

Question #3
A wave has frequency 50 Hz and wavelength 2 m. Its speed is:
A. 200 m/s
B. 25 m/s
C. 50 m/s
D. 100 m/s

Correct Answer: Option D


Explanation:
Wave speed v = frequency (f) × wavelength (λ). Thus v = 50 Hz × 2 m = 100 m/s. This fundamental wave equation applies to all periodic waves (sound, light, water). Memory aid: 'v = fλ – the universal wave equation'. Competitive exams frequently test this direct calculation. Always ensure units: Hz = s⁻¹, so (s⁻¹)×m = m/s, correct for speed. This problem assesses basic wave property understanding, crucial for sound and light topics.
