Answer:
The sound will reach my ear in a shorter time in Scenario 1.
The speed of sound waves in solids is faster than it is in gases.
Explanation:
The sound which is produce due to hitting of metal bar with a drumstick reaches to the ears in short time because sound is a longitudinal wave which requires or needs medium for its propagation from one place to another and in solids the particles of medium are close to each other as compared to air so the sound travels faster in solid materials as compared liquid and gases and takes less time to reach my ears.

Explanation:
halocline
wind

Convection currents flow due to variations in the temperature and salinity in seawater, which both influence its density. Variations in density in different regions of the ocean will cause water to flow from less dense areas to more dense areas as water heats up and becomes less saline, producing a horizontal convection current. Vertical convection currents can arise as cooler, more saline water sinks, causing warmer, less saline water to rise.
The bacterial capsule is a well-organized layer of material lying outside the bacterial cell wall serving to protect the bacteria and which is not easily washed off.
<h3>What is the bacterial capsule?</h3>
The bacterial capsule is a well-organized layer of material lying outside the bacterial cell wall and which is not easily washed off.
The bacterial capsule is a layer of polysaccharides which are found outside the cell envelope, therefore, it is regarded as being part of the outer envelope of a bacterial cell.
The bacterial capsule is associated with being the cause of various bacterial diseases.
