Which of the following minerals contains manganese?
- Galena
- Cinnabar
- Pyrolusite
- Horn silver
The Correct Option is C
Solution and Explanation
Correct answer: Pyrolusite
Explanation:
Pyrolusite is a mineral that contains manganese dioxide (MnO₂). It is one of the most important ores of manganese.
Here’s what the other minerals contain:
- Galena – Lead sulfide (PbS)
- Cinnabar – Mercury sulfide (HgS)
- Horn silver – Silver chloride (AgCl)
Top Questions on Corrosion
The figure shows a rod PQ, hinged at P, rotating counter-clockwise with a uniform angular speed of 15 rad/s. A block R translates along a slot cut out in rod PQ. At the instant shown the distance \( PR = 0.5 \, {m} \) and \( \theta = 60^\circ \). The relative velocity of R with respect to the rod PQ is 5 m/s at the instant shown. The relative acceleration of R with respect to the rod PQ is zero at the instant shown.
Which one of the following is the CORRECT magnitude of the absolute acceleration (in m/s\(^2\)) of block R?
Consider two blocks, P of mass 100 kg and Q of mass 150 kg, resting as shown in the figure. The angle \( \theta = 30^\circ \). The coefficient of friction between the two blocks is 0.2.
