Among the given gases, the green house gases which are responsible for heating the atmosphere are \(CH_4\), water vapour and ozone.
Nitrogen is not a green house gas.
Therefore, the correct option is (D): \(N_2\)
In the given circuit the sliding contact is pulled outwards such that the electric current in the circuit changes at the rate of 8 A/s. At an instant when R is 12 Ω, the value of the current in the circuit will be A.
Let $ P_n = \alpha^n + \beta^n $, $ n \in \mathbb{N} $. If $ P_{10} = 123,\ P_9 = 76,\ P_8 = 47 $ and $ P_1 = 1 $, then the quadratic equation having roots $ \alpha $ and $ \frac{1}{\beta} $ is:
For $ \alpha, \beta, \gamma \in \mathbb{R} $, if $$ \lim_{x \to 0} \frac{x^2 \sin \alpha x + (\gamma - 1)e^{x^2} - 3}{\sin 2x - \beta x} = 3, $$ then $ \beta + \gamma - \alpha $ is equal to:
It is also called sustainable chemistry and it is an area of chemistry where chemical engineering focused on the designing of products and processes that minimizes the use and generation of hazardous substances.
