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:
<u>Provide support and energy</u>
Explanation:
Polysaccharides are made up of many monosaccharides the common types include starch, cellulose, glycogen, chitin and lignin. Starch is present as stored food in plant tissues and can be hydrolysed into monosaccharides to provide energy.
Cellulose and chitin are structural components. They give the plan cells their definite shape and the exoskeleton in arthropods respectively.
Answer:
the leaf disk should float because bicarbonate is the source of its oxygen for photosynthesis and it releases oxygen into the interior of the disk causing it to float.
