Atmospheric pressure at sea level in pascal is approximately
A. 1.01 × 10⁹ Pa
B. 1.01 × 10³ Pa
C. 1.01 × 10⁵ Pa
D. 1.01 × 10⁷ Pa
Answer: Option C
Solution (By JKSSB Mock Tests)
Standard atmospheric pressure 1 atm = 1.01325 × 10⁵ Pa ≈ 1.01 × 10⁵ Pa = 101 kPa. Also equals 760 mm of Hg. This is an important conversion for pressure units.
Explanation:
Methane (CH₄) is primary component. LPG is mainly propane and butane. CNG is compressed methane. This relates to everyday physics and chemistry.
Explanation:
Frequency = vibrations per second. 500 vibrations per second. In 2 min = 120 s, total vibrations = 500 × 120 = 60,000. Simple multiplication.
