Scientists use weather tools to figure out if there is a big storm/tornado/hurricane so they can warn the people to prepare for whatever is coming
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 Ozone Layer would repair
Explanation:
CFC's are chlorofluorocarbons. They generally eat the ozone layer. It stands to reason that a reduction in CFC's would reduce the depletion of the ozone layer allowing it to slowly repair itself through natural processes.
