Rate of Discharge
What is measured by Specific gravity of a lead acid cell?
Specific gravity of the electrolyte in the lead acid cell or battery (assuming that the battery is not of the sealed type) is often used as a measure of its STATE OF CHARGE. Sure we can do the same with a multimeter but the above method is more accurate.
What is specific gravity?
Specific gravity, usually referred to as relative density is the ratio of the mass of a given volume of a substance to the density of a different reference substance. Water is often used as the reference.
What is the best way to determine how much of a substance dissolved in water?
Density and specific gravity are often used to measure the relative concentrations of a known solvent and known solute.A Hydrometer is a common device for measuring specific gravity of liquids.
Is a gram a measure of length?
A gram is often thought to be a measure of weight but it is really measure of mass. A gram serves as a unit for weight only when in the gravity field of the Earth.
Why is weight measured Newton?
Weight is the measure of the force with which the Earth's gravity is pulling an object to its center. Since it is a measure of force, it is often expressed in Newtons.
What does a spectrometer measure?
A spectrometer measures properties of light of a specific part of the wavelength. It is often used to measure the intensity of a light.
What term is defined as a measure of the pull of gravity of an object?
That quantity is a force, whose magnitude we often refer to as the object's "weight".
What term is defined as a measure of the pull of gravity on an object?
That quantity is a force, whose magnitude we often refer to as the object's "weight".
How will the specific gravity of urine be affected by the presence of sugar?
Since specific gravity is the density of a substance relative to water, dissolving solids such as sugar will increase it. Here's an extreme example: think of placing a floating object in water, then placing the same object in honey. It's easy to imagine the object floating higher in thick honey than it would on water, right? Honey has a higher specific gravity than water, and floating a hydrometer in a liquid is how its specific gravity is often measured.
What are some examples of physical quantities that do not have units?
This often happens if you take the ratio of two quantities. In that case, the units disappear. For example:* A coefficient of friction, defined as the ratio between two forces * The specific gravity, defined as a ratio between two densities
What is the Specific Gravity of air?
Specific gravity is often defined relative to water, in which case the specific gravity of air is 0.001225. Specific gravity can also be defined relative to the density of air, in which case the specific gravity of air is exactly 1. Specific gravity is often defined relative to water, in which case the specific gravity of air is 0.001225. Specific gravity can also be defined relative to the density of air, in which case the specific gravity of air is exactly 1.
