In this article, we shall study the concept of dimensions of physical quantities and to find dimensions of given physical quantity. Dimensions of Physical Quantity:.

This article mainly focuses on the dimensions of physical quantities, dimensional formulas and dimensional analysis. Before going through the dimensions and dimensional formulas, first you require a piece of basic knowledge about the basics of measurement and for that consider reading my previous article about the measurement and different system of units. All physical quantities can be expressed in terms of seven fundamental base quantities such as mass, length, time, temperature, electric current, luminous intensity and amount of substance. These seven quantities are called the seven dimensions of the physical world.

Physics is a quantitative science, based on measurement of physical quantities. Certain physical quantities have been chosen as fundamental or base quantities. The fundamental quantities that are chosen are Length, Mass, Time, electric current, thermodynamic temperature, amount of substance, and luminous intensity. Each base quantity is defined in terms of a certain basic arbitrarily chosenbut properly standardised reference standard called unit such as metre,kilogram,second,ampere,kelvin,mole,and candela. The units for the fundamental base quantities are called fundamental or base units and two supplementary units in relation to quantities plane angle and solid angle radian, Ste radian.. Other physical quantities derived from the base quantities can be expressed as a combination of the base units and are called derived units.

Make that one idea your life - think of it, dream of it, live on that idea. Let the brain, muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. This is the way to success, that is way great spiritual giants are produced. The dimensional formula of Density is incorrect. It should be M to the power 1, L to the power

Physicists, like other scientists, make observations and ask basic questions. For example, how big is an object? How much mass does it have? How far did it travel? To answer these questions, they make measurements with various instruments e.

Figure 1. The distance from Earth to the Moon may seem immense, but it is just a tiny fraction of the distances from Earth to other celestial bodies. We define a physical quantity either by specifying how it is measured or by stating how it is calculated from other measurements. For example, we define distance and time by specifying methods for measuring them, whereas we define average speed by stating that it is calculated as distance traveled divided by time of travel.

 - Она окинула Бринкерхоффа оценивающим взглядом.  - У тебя есть ключ от кабинета Фонтейна. - Конечно.

 Офицер полиции этого не знает. - Не имеет понятия. Рассказ канадца показался ему полным абсурдом, и он подумал, что старик еще не отошел от шока или страдает слабоумием. Тогда он посадил его на заднее сиденье своего мотоцикла, чтобы отвезти в гостиницу, где тот остановился.

Она нашла то, что искала, вернулась со справочником к своему терминалу, ввела несколько команд и подождала, пока компьютер проверит список команд, отданных за последние три часа. Сьюзан надеялась обнаружить внешнее воздействие - команду отключения, вызванную сбоем электропитания или дефектным чипом.

Халохот повернулся к алтарю. В тридцати метрах впереди продолжалось святое причастие. Падре Херрера, главный носитель чаши, с любопытством посмотрел на одну из скамей в центре, где начался непонятный переполох, но вообще-то это его мало занимало.

В ужасе от того, что ее ожидало, она направилась к кабинету шефа. Когда Сьюзан уже сделала несколько шагов, что-то вдруг показалось ей странным. Она остановилась и снова начала вглядываться в глубь помещения Третьего узла.

 - Танкадо был известен стремлением к совершенству. Вы сами это знаете. Он никогда не оставил бы жучков в своей программе.
