Question 1 of 10
1. Question
1 pointsConsider the following statements:
-
- Sodium-ion batteries have lower energy density compared to Lithium-ion batteries.
- Sodium-ion batteries use sodium ions as the charge carriers instead of lithium ions.
- Sodium-ion batteries are not suitable for high-performance applications due to their low capacity.
How many of the above statements are correct?
Correct
Ans: (c)
Explanation:
- All statements are correct.
- S3: Sodium-ion batteries may not be suitable for high-performance applications like consumer electronics or electric vehicles but could find application in low-speed vehicles or specific energy storage scenarios.
Feature Sodium-ion Batteries Lithium-ion Batteries Cost Generally lower cost due to the abundance of sodium (Sodium is 500-1000 times more abundant than lithium). Higher cost due to the scarcity of lithium and its extraction process. Energy Density Lower energy density compared to lithium-ion batteries. Higher energy density, providing more power in a smaller size. Cycle Life Generally lower cycle life compared to lithium-ion batteries. Longer cycle life, retaining capacity over more charge-discharge cycles. Safety Generally safer due to the less reactive nature of sodium. Generally safe but can be prone to thermal runaway under certain conditions. Environmental Impact Sodium is more abundant and less harmful to the environment. Lithium extraction and disposal can have environmental consequences. Application Suitable for large-scale energy storage and grid applications. Widely used in consumer electronics, electric vehicles, and portable devices. Refer: https://www.insightsonindia.com/2024/04/24/sodium-ion-battery/

Question 3 of 10
3. Question
1 pointsConsider the following statements:
-
- Butterflies are cold-blooded creatures.
- Butterflies only feed on nectar from flowers.
- Butterflies have four wings and six legs.
- Butterflies undergo complete metamorphosis, including egg, larva, pupa, and adult stages.
How many of the above statements are correct?
Correct
Ans: (c)
Explanation:
- Statements 1, 3 and 4 are correct.
- S1: Butterflies are cold-blooded, meaning they cannot regulate their own body temperature. As a result, their body temperature changes with the temperature of their surroundings. If they get too cold, they are unable to fly and must warm up their muscles in order to resume flight.
- S2: The main source of food for butterflies is the nectar from flowers, and because there are few nutrients in flower nectar, male butterflies of most species land at the edge of a wet area where they feed on essential salts and other nutrient found in sand or mud.
- S3: Butterflies have six jointed legs, a pair of antennae and three body parts called a head, thorax (chest), and abdomen (tail end). The four wings and the six legs of a butterfly are attached to its thorax.
- S4: Butterflies and moths undergo a complete metamorphosis, which means there are four separate stages in the life cycle (egg, larva, pupa, and adult). Each stage looks completely different and serves a different purpose in the life of the insect.

Question 7 of 10
7. Question
1 pointsWhich of the following statements about Mount Erebus is correct?
Correct
Ans: (d)
Explanation:
- Context: Mount Erebus, located in Antarctica, is raining gold on Earth, spewing out approximately 80 grams of gold worth $6000 daily, according to NASA’s Earth Observatory. However, the remote location makes it impossible for anyone to claim this fortune, ruling out any possibility of a gold rush.
