the numbers that show the units used on the axes of a graph are called .

The numbers that show the units used on the axes of a graph are called_______. => scale or sector or coordinate or number..

Introduction - We use specific number of digits to denote an exact value of a number for required accuracy. The digits used for such a purpose are called significant figures. Suppose a measurement is recorded as 0.6204 cm. It means that the measurem..

> The above results can be summarized as follows: When a reaction proceeds, the number of moles converting from reactants to the products may or may not change. The change in the number of moles (except for pure liquids, solids and solvent in excess) converting from reactants to..

In a Rectangular Cartesian System of coordinates the position of a point in a plane is determined by an ordered pair whose elements give the distances from the intersecting straight lines at right angles to each other. These lines are called the axes. The vertical line is ..

Most experiments in physics require the observations made to be quantitative rather than qualitative. If observations are only descriptive or qualitative, they are likely to be imprecise and could cause disagreements between experimenters. For example, scientists cannot merely say that an object i..

For a proper discussion of the three phases of matter, we require a three-dimensional diagram in which P, V and T should be plotted against three mutually perpendicular coordinate axes. This diagram, known as P-V-T diagram, is difficult to draw on paper. Hence, we generally ignore V and d..

The condition in which a particular material exists is described by physical quantities such as pressure, volume, temperature and amount of substance. For example, a tank of oxygen in a welding outfit has a pressure gauge and a label stating its volume. We could add a thermometer and place the tank..

Electroencephalography - Brain cells can generate electrical activity as a result of literally millions of action potentials of individual neurons. These electrical potentials are called brain waves and indicate activity of the cerebral cortex. Brain waves pass through the skull easily an..

The Ideal Gas Equation - Another simple equation of state is the one for an ideal gas. The figure below shows an experimental setup to study the behavior of a gas. The cylinder has a movable piston to vary the volume, heating can vary the temperature, and we can pump the desired amount of any gas i..

. Can you tell where each of them would be after say 20 seconds? P and Q can move in any direction. To locate the exact position of P and Q we require their direction of motion als..
