Answer:
A scientist who studies thermodynamics might experiment with the instant ice packs where you have to pop a bag on the inside to create a chemical reaction to make it cold.
<span>They allow us to see distant objects as they were long in the past.

Okay, so the density of water is 1g/cm3. In order for the cube to float, it has to be less than 1, and it will sink if it is more than 1 g/cm3. Use a triple beam balance to weigh the cube, looking at the metric ruler on the balance. Then, if the cube's density is more than 1, then you know it will float. If the density is less than 1, you know it will sink.
hope this helps, and I didn't know how to use the word "metric ruler"
Answer
Correct Answer is C (10% of the plant's energy is transferred
Explanation:
Ecosystem
ecosystem is a community where large number of living organisms lives. These living organism are plants, trees, different types of animals, birds etc. These living organism depends on each other for their food.
Their are various levels in ecosystem like producer, primary consumer, secondary consumer and tertiary consumer.
producer like plants produce their food on their own. And primary consumers takes their food from producers.
According to 10% Rule of ecology only 10% energy is passed from one level to another.So 10% of the plant's energy is transferred
