1 joule 948 x 10-4 BTU.

. Now taking option C. Some other traditional measures however are adopted to serve as units of power. The following is a list of definitions relating to conversions between joules and kilocalories.

Named in honour of the English physicist James Prescott Joule it equals 10 7 ergs or approximately 07377 foot-pounds. View solution Which one of the following units is a fundamental unit. Mathematically the energy is given by force times the displacement.

1 joule 2778 x 10-7 kWh. It is equal to the energy transferred to an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre. Joule is the unit of workenergy in the International System of Units or SI.

Kgm2s-2 is the SI base unit of Joule. 1 joule 0239 Calories. The two type aid mechanical energy are.

Joule is the correct answer because it is the unit of energy. It is expressed as the work required to produce one watt of power for one second. F m a where m mass of object a acceleration.

1 J 1 Nm. And one meter is one joule. M L 2 T 1.

Joule is unit of heat energy and work. From this we can conclude that it is also a derived unit. 1 Watt 1 Jouleover Second Joule is the SI unit of Energy.

The unit watt is named after scientist James Watt. View solution View. The SI unit of power is a watt which equals one joule per second.

The electron volt is the unit of energy commonly used in atomic and nuclear physics. What is a kilocalorie kcal. The joule is equal to the amount of work that is done when a 1N force is applied over a distance of 1m.

The Joule 10-year warranty covers Joule Wellmaster cylinders installed in domestic properties against corrosion for a period of 10 years from date of purchase. The potential energy of a pendulum is greatest. Which of the following is a unit of energy.

They include calories per hour horsepower kilowatt joule per second foot-pounds per minute etc. View solution Column I gives three physical quantities. Some of the physical quantities may have more than one choice.

It is equal to the work done by a force of one newton acting through one metre. Joule unit of work or energy in the International System of Units SI. All other components including valves.

When the kinetic energy of a simple pendulum decreases the - potential energy. A joule is a unit of energy in the International System of Units SI. Power is defined as the rate of doing work.

Which one of the following is not a fundamental SI unit. S 2 1 kg meter square per second square The Dimensional formula for Joulesec is. Wellmaster cylinders must be maintained annually and the sacrificial anode changed on the annual service to maintain this warranty period.

Therefore the joule has units of Nm or kgm2s2 which are all SI units themselves. When a force of 1 Newton acting on a body through a distance of 1m. So 1 joule 1 k g.

Joule is a unit of energy and is indicated by J. Therefore force cannot have the same unit as energy. Select the appropriate units for these from the choices given in column II.

And Vectors 2 Motion In One Dimension 3 Motion In Two Dimensions 4 Newtons Laws Of Motion 5 Energy 6 Momentum Impulse And Collisions 7 Rotational Motion And Gravitation 8 Rotational Equilibrium And Dynamics 9 Fluids. Joule is a derived unit of energy. The calorie with a lower case c has been the traditional unit of energy defined as the amount of energy needed to raise 1 gram of water 1C.

Energy for an object is defined as the work done on the object. There are 4184 joules in a kilocalorie. We know that joule is the derived unit of angular momentum.

Which of the following unit is not same. The unit Joule is named after the English physicist James Prescott Joule. Hence joule is not the unit of force.

The symbol for joule is J. Joules per second D.
