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.
The patient should be triaged in "critical", color coded as red. This is because a bomb blast can lead to multiple gross organ damages such as fractures (pelvic fractures most commonly produce the greatest amount of internal hemorrhage which can lead to shock), liver and spleen rupture that can cause hemorrhagic shock, and burns that can predispose the patient to fluid lose and electrolyte imbalance which then, if untreated, will lead to kidney and cardiac compromise.
Other triaging priorities for other patients include urgent and non-urgent cases.
Scientists use triangulation to find the epicenter of an earthquake. When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects.
