Solution

The correct option is D Both 1 and 2 are true
A sound is a form of energy, just like electricity. A sound is made when air molecules vibrate and move in a pattern called waves, or sound waves. ... That action produces sound waves, which travel to your ears and then to your brain, which says, "I recognize that sound."

In fact, visible 'light' is a form of radiation, which can be defined as an energy that travels in the form of electromagnetic waves. It can also be described as a flow of particle-like 'wave-packets, called photons.

Choose the correct option.

Statement $1 : (p \land \sim q) \land (\sim p \land q)$ is a fallacy.

Statement $2 : (p \Rightarrow q) \Leftrightarrow (\sim q \Rightarrow\sim p)$ is a tautology.

F (x) = \int_{1}^{x} \frac{l o g t}{1 + t + t^{2}} d t

F (x) = - F (\frac{1}{x})

F (x) = \int_{1}^{x} \frac{l o g t}{1 + t} d t

F (x) + F (\frac{1}{x}) = \frac{1}{2} (l o g x)^{2}
