The efficiency of work is a dimensionless value, and is equivalent to the ratio of the actual work output to the theoretical work requirement. This can be calculated using the equation:
Efficiency = (actual work) / (work requirement) = 123/150 = 0.82
The higher the efficiency, the better performance is given by the system. In reality, efficiency is always lower than 1 which is the ideal value.
Answer;
-The less dense, the more the ice will float, allowing animals to stay afloat and not in the water
Explanation;
-When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density.
-This means that ice floats on water and that lakes freeze from the top down to the bottom.This is vital for animals that live on ice, as their habitats would be greatly reduced or not exist at all if ice sank.
Answer:
O coral bleaching
Explanation:
Without the algae, corals lose their color and turn white. This is called “coral bleaching “.
You can essentially mix and match, not only that but there are so many, too, which accounts for the variety.
