The correct Answer is:
To solve the question, we need to identify the organ that meets the following criteria: 1. **Shape**: Oval 2. **Covering**: Dense covering 3. **Location**: Lies in an extra-abdominal pouch 4. **Temperature**: Has a temperature 2 to 1.5 degrees Celsius lower than the body temperature ### Step-by-Step Solution: **Step 1: Analyze the Options** - The options provided are ovary, eyeball, testis, and epididymis. - We need to determine which of these options fits all the criteria. **Step 2: Consider the Testis** - The testis is known to be oval in shape. - It has a dense covering (the tunica albuginea). - The testis is located in the scrotum, which is an extra-abdominal pouch. - The temperature of the testis is indeed lower than the body temperature, typically around 2 to 2.5 degrees Celsius lower, which is essential for the process of spermatogenesis (sperm production). **Step 3: Evaluate Other Options** - **Ovary**: While it is an organ that produces gametes, it is not located in an extra-abdominal pouch. - **Eyeball**: This is not an organ related to gamete production and does not fit the criteria. - **Epididymis**: This is a structure associated with the testis but is not oval in shape and does not have a separate pouch. **Step 4: Conclusion** - Based on the analysis, the only organ that fits all the criteria is the **testis**. ### Final Answer: The organ that is oval in shape, has a dense covering, lies in an extra-abdominal pouch, and has a temperature 2 to 1.5 degrees Celsius lower than the body is the **testis**. ---

    Newton’s law of cooling says that the rate of cooling of a body is proportional to the temperature difference between the body and its surrounding when the difference in temperature is small. (a) Will it be reasonable to assume that the rate of heating of a body is proportional to temperature difference between the surrounding and the body (for small difference in temperature) when the body is placed in a surrounding having higher temperature than the body? (b) Assuming that our assumption made in (a) is correct estimate the time required for a cup of cold coffee to gain temperature from 10^(@)C to 15^(@)C when it is kept in a room having temperature 25^(@)C . It was observed that the temperature of the cup increases from 5^(@)C to 10^(@)C in 4 min

The end with radius a is maintained at a higher temperature T_(1) and the other end is maintained at a lower temperature T_(2) . The curved surface is insulated. (i) At which of the two points – 1 and 2 – shown in the figure will the temperature gradient be higher? (ii) Calculate the thermal resistance of the rod.
