Joule is a unit of work or energy. He expended 500 joules of energy lifting the weight. 19 Watt The watt (symbol: W) is a unit of power or radiant flux. In the International System of Units (SI), it is defined as a derived unit of (in SI base units) 1 kg⋅m2⋅s−3 or...
Why more viscous oil is used in a motor car in summer than in winter? What is 3 joules in fps? What is an anisotropic dielectric material? What is inertia? Name four dimensionless quantities. What is the electromotive force? What is an ideal liquid?
It is also equal to one watt of power emitted or dissipated for one second, or watt second (Ws). In various applications, British thermal units (BTU) are used to express the unit for energy. One BTU is equal to approximately 1,055 joules. One joule is equal to: 1× 107 erg (...
What is 3 joules in fps? (a) How much more electrical energy is produced by the more efficient power station? (b) How much less heat transfer occurs to the environment by the more efficient power station? What is the equivalent of 1 kWh in Joule?
is usually expressed in joules according to theInternational System of Unitsor inBritish thermal unitsaccording to thefoot-pound-secondor English system. If this energy is used to operate an electricity generator, the output of the generator over a period of time can be expressed in watt-hours....
How many kilowatts are in a megawatt? One megawatt is equal to 1,000 kilowatts. How much energy does one megawatt-hour produce? One megawatt-hour is equivalent to 3.6 million joules of energy and is capable of powering a home for 1.2 months, or 3,600 miles driven by an electric car....
Work and energy can both be measured in joules. Power is the rate at which energy is used up and is measured in watts. Using up 1 J of energy for one second uses 1 watt of power, so 1 watt is 1 joule per second. A 100-watt light bulb uses 100 J of energy per second. ...
as,1 Atm = 101325 pascals, while1 dyn/cm2 = 0.1 pascals. thank you. What is the unit of power? Power (P) is the rate at which energy is transferred or converted. Thus, power equals work divided by time (P = W / t). The SI unit of power isthe watt (W), in honor of Scot...
Readings are taken during each billing period. The common billing unit is kilowatt-hour (kWh), which equals the use of one kilowatt of power for one hour or 3,600,000 joules. The Watt-Hour Meter is often referred to as an energy meter or electric meter or electricity meter, or electrica...
Power is defined as work divided by time, so its units are joules/second. Scientists have another name for this unit, too. It's the watt, named after James Watt, the Scottish inventor who helped develop the steam engine that powered the Industrial Revolution. In the SI system, the watt ...
