111. Which equation shows the reaction of photosynthesis?
- Option : B
- Explanation : (B) 6CO2 + 12H2O → C6H12O6 + 6O2 + 6H2O
Plants synthesis glucose sugar with the help of CO2 and H2O molecules is presence of chloroplast and sunlight.
- Option : A
- Explanation : (A) Given resistances are R1 = 1Ω, R2 = 2Ω and R3 = 3Ω
These three resistors are connected in parallel. Therefore equivalent resistance is
113. The relation between speed of sound (v) and absolute temperature (T) in a gas is
- Option : B
- Explanation : (B) Speed of sound (v) in a gas is directly proportional to the square root of absolute temperature (T) of the gas.
i.e. v ∝ √T
114. The momentum of particle having mass m, is p. Its kinetic energy will be
- Option : D
- Explanation : (D) Momentum of two particle of mass (m) is p = mv
Kinetic energy of the particle is
- Option : D
- Explanation : (D) The potential difference across the conductor is v = e = constant
Let resistance of the conductor is R.
Therefore, heart generated in the conductor is time t is
∴ e, R and t are constants
H ∝ e2
