Question : A cycle tyre bursts suddenly. This represents an:
Option 1: Isothermal process
Option 2: Adiabatic process
Option 3: Isochoric process
Option 4: Isobaric process

Solution : The correct option is the Adiabatic process.
Heat transmission occurs after the bursting, it may be said that very little energy is exchanged during the event. It happens due to the Adiabatic process. It is a thermodynamic process that occurs without transferring heat
Question : $\cos^4 A-\sin^4 A$ is equal to:
Option 1: $2 \cos^2 A+1$
Option 2: $1-2 \sin ^2 A$
Option 3: $2 \sin^2 A-1$
Option 4: $-\left(2 \sin^2 A+1\right)$
Correct Answer: $1-2 \sin ^2 A$
Solution : Given: $\cos^4 A-\sin^4 A$ $= (\cos^2A)^2-(\sin ^2A)^2$ $= (\cos^2A-\sin^2 A)(\cos^2 A+\sin^2 A)$ $= (\cos^2A-\sin^2A)×1$ [$\because \cos^2A+\sin^2A=1$] $=(1-\sin^2A-\sin^2A)$ $= 1-2\sin^2A$ Hence, the correct answer is $1-2\sin^2A$.
