Measured about O, what is the combination's kinetic energy in joules? Can pontential energy ever be negative? How long does it take to do 432 joules of work with 75 watts of power? Kinetic and potential energy are energy states. What does this mean? Give an example of each. What is ...
How many joules are in a Watt? Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it's running. So a 60W bu...
How many joules are in a watt? What is mu in Ampere's law? When was Joule's law established? What does a photon energy unit of a Joule equal? What are the units of work and energy? What is mu in Faraday's law? What is the constant in Ampere's law? What is B in Ampere's ...
Speed and distance are also useful analogies to wattage and watt-hours. For example, an automobile may run at 60 miles per hour. That's analogous to watts, in that the car's speed at any moment is 60 mph. If the car travels at 60 mph for one hour, it travels 60 miles in distance...
Note:In the same way that there are joules, there are also kilojoules (1000 joules) and the concept is identical although I don’t think there is the same nonsensical bs about upper and lower case letters. Since 1 calories is equivalent to 4.2 joules, 1 kcal is the equivalent of 4.2 ...
Power is essentially the flow rate of water in the hose, based on its pressure and volume. Electric power is measured in watts (W), kilowatts (kW), and megawatts (MW). Energy is the amount of water that comes through the hose over a period of time. That’s why your electric bill ...
You don’t have to spend a lot on a great one, but even a basic power strip surge protector with a few hundred joules of dissipating potential will go a long way to ensuring that power spikes from the grid, or simply turning on a hair dryer in your home, won’t lead to other devi...
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....
of interest and contribute noise to the signals. The noise spectrum produced by thermal noise is nearly uniform over RF and microwave frequencies. The power delivered by a thermal source into an impedance matched load is kTB watts, where k is Boltzmann’s constant (1.38 x 10-23 joules/K),...
(physics) the rate of doing work; measured in watts (= joules/second) Power Possession of the qualities (especially mental qualities) required to do something or get something done; Danger heightened his powers of discrimination Power A state powerful enough to influence events throughout the worl...
