For the word puzzle clue of unit of power in the si unit system 1 equaling a single joule per second, the Sporcle Puzzle Library found the following results. Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. Watt is a scalar quantity, which means it doesnt contain direction. It is also possible to change the shape of energy. Kilowatt-hour (kWh) is a large practical unit of work and energy. The SI derived unit As of June 2016, the Green500 list rates the two most efficient supercomputers highest those are both based on the same manycore The watt-second is referred to as joules. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately The stream engine is the most well-known of his inventions. The answer is 1.0E-13. The watt-second is the energy equivalent to the power of one watt sustained for one second . Called watt. The newton is a Ans: Horse Power (HP) is another unit of Power, which is largely used in mechanical engineering. 1 watt is equal to 1 joules/second, or 0.2388458966275 Btu per hour (Btu/h) is sometimes used in North America and the United Kingdom - the latter for air conditioning mainly, though "Btu/h" is sometimes abbreviated to just "Btu". An oil pump is drawing 44 kW of electric power while pumping oil with = 860 kg/m^3 at a rate of 0.1 m^3/s. Joule is the 3600th part of a watt-hour. The watt is the most often used unit of power measurement. Joules depend on newton and watt which is the unit of power depends on joules. Stop lugging your AC adapter back and forth between home and office. 1 W is approximately 3.412142 Btu/h Hence, the correct option is (d) "The unit for work is a joule. Power: A body is said to have one watt of power if it can perform one joule of work in one second.

Right answer: a Joule divided by a second The Watt is the unit of Electrical Power of the International System of Units that is equivalent to a Joule () per second () and the symbol that identifies this unit is : In other words, this unit represents the amount of energy (in Joules) delivered or absorbed by an element in a given time (in seconds). to ensure we have enough power in our circuits to power our appliances. Since watts are equivalent to volts multiplied by amps, a voltage ampere is equivalent to a watt. Calculate the energy consumed by both the bulbs in one day. Watt is the SI unit of power. In physics, power is referred to as the time rate of doing work or delivering energy, which is expressed as the amount of work done W (energy transferred), divided by the time interval t. A certain amount of work can be done either by a low-powered motor in a long time or by a high-powered motor in a short time. Plainmath.net is owned and operated by RADIOPLUS EXPERTS LTD.
