Ship measurements include overall length (LOA), perpendicular intership length (LBP), load waterline length (LWL), width, and depth. LBP provides better estimates of carrying capacity, while LWL is used to calculate speed and water resistance. Depth is measured from the lowest point on the hull to a reference point on the ship’s side. Ship measurements are […]
Electrical measurements include voltage, current, power, resistance, and electromagnetic fields. Meters are used to measure these quantities, and a multimeter combines the functions of an ammeter, voltmeter, and ohmmeter. The electric field around a conductor can be measured with a Hall sensor or an electrometer. Electrical characteristics of circuits and components can be inferred from […]
Electrical measurements involve measuring voltage, current, power, resistance, and electromagnetic fields. Meters are used to measure these quantities, and a multimeter combines the functions of an ammeter, voltmeter, and ohmmeter. The characteristics of electrical circuits and components can also be measured, such as inductance and capacity, using calculations based on measurable quantities. The electric field […]
Qualitative measures include participant observation, direct observation, unstructured interviews, and case studies. They are based on unfocused data and are difficult to quantify. Participant observation involves the researcher actively participating in the culture or group being studied, while direct observation involves the observer occupying the role of an observer. Unstructured interviews are subjective, and case […]
The US uses the imperial system of measurement, but the metric system is used in science and medicine. The metric system is also taught in schools, but conversions can be difficult. Children must learn both systems, but unless they become scientists or exporters, they may never fully master the metric system. The US government needs […]
