The correct Answer is:
To solve the question regarding the type of fruit described, we will analyze the characteristics provided and match them with the correct type of fruit. ### Step-by-Step Solution: 1. **Identify the Characteristics of the Fruit**: - The fruit has an endocarp with sub-epidermal juice sacs or hairs on the inner side of its locules. - It has a spongy white mesocarp. - The epicarp is leathery and contains oil glands. 2. **Analyze the Options**: - **Pome**: This type of fruit develops from a syncarpous inferior ovary and is surrounded by a fleshy thalamus. Examples include apples and pears. However, it does not match the characteristics mentioned in the question. - **Pepo**: This fruit type develops from a tricarpillary syncarpous unilocular inferior ovary. It also does not have the specific features described in the question. - **Drupe**: A drupe has three layers: epicarp, mesocarp, and endocarp, with a hard and stony endocarp. Examples include mangoes and coconuts. This does not match the characteristics either. - **Hesperidium**: This is a type of berry with a leathery epicarp and a spongy mesocarp. The endocarp is juicy and has inward projections forming chambers, which contain sub-epidermal juice sacs or hairs. Examples include citrus fruits like oranges and lemons. 3. **Conclusion**: - Based on the analysis, the fruit described in the question matches the characteristics of a **Hesperidium**. Therefore, the correct answer is **Hesperidium**. ### Final Answer: The fruit described is called **Hesperidium**. ---

When a sound wave enters the ear, it sets the eardrum into oscillation, which in turn causes oscillation of 3 tiny bones in the middle ear called ossicles. This oscillation is finally transmitted to the fluid filled in inner portion of the ear termed as inner ear, the motion of the fluid disturbs hair cells within the inner ear which transmit nerve impulses to the brain with the information that a sound is present. The theree bones present in the middle ear are named as hammer, anvil and stirrup. Out of these the stirrup is the smallest one and this only connects the middle ear to inner ear as shown in the figure below. The area of stirrup and its extent of connection with the inner ear limits the sensitivity of the human ear consider a person's ear whose moving part of the eardrum has an area of about 50mm^2 and the area of stirrup is about 5mm^2 . The mass of ossicles is negligible. As a result, force exerted by sound wave in air on eardum and ossicles is same as the force exerted by ossicles on the inner ear. Consider a sound wave having maximum pressure fluctuation of 4xx10^-2Pa from its normal equilibrium pressure value which is equal to 10^5Pa . Frequency of sound wave in air is 332(m)/(s) . Velocity of sound wave in fluid (present in inner ear) is 1500(m)/(s) . Bulk modulus of air is 1.42xx10^5Pa . Bulk modulus of fluid is 2.18xx10^9Pa . Q. Find the displacement amplitude of given sound wave in the fluid of inner ear.
