Show Hint
- acid rain
- soil pollution
- global warming
- water pollution
The Correct Option is A
Solution and Explanation
CaCO3 + H2SO4 \(\rightarrow\) CaSO4 + H2O + CO2, which corrodes and discolours the marble ('marble cancer').
Answer: (1) acid rain

Top JEE Main Questions
- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
