How to convert energy in joules (J) to electric power in watts (W).You can calculate watts from joules and seconds, but you can't convert joules to watts, since joule and watt units represent different quantities.Joules to watts calculation formulaThe power P in watts (W) is equal to ...
P is the power in watts, W is the work in joules, and t is the time in seconds. Considering the relationship between torque and power, if we know the rate of rotational speed, otherwise known as the angular velocity, we can calculate power. Power is (force × distance)/time. Consi...
How much energy, in joules, is used by a football player if he pushes a blocking sled for two minutes while generating 40 watts of power? Find the change in electric potential energy between two charges that are initially a distance r1 apart and later a distance r2 apart. Use variables ...
How long does it take to do {eq}432 {/eq} joules of work with {eq}75 {/eq} watts of power?Question:How long does it take to do {eq}432 {/eq} joules of work with {eq}75 {/eq} watts of power?Power:The term power can be explained as the measure of energy ...
That's how many joules (the standard measurement of energy) you'd get from a kilogram of mass. In theory, if you could turn about seven billion hydrogen atoms completely to energy, you'd get about one joule (that's about as much energy as a 10-watt lightbulb consumes in a tenth of...
How many joules of potential energy does a 1.5 kg book gain when it is elevated 4.2 m?Potential Energy:Potential Energy is the energy carried by an object at rest due to its position in relation to other objects, stress introduced relative to a spring system and electric...
A smartphone's charging capability is typically defined by the highest wattage supported by it. Electric power is the rate at which electric energy is transmitted, and it's expressed in watts (W) or joules per second (J/s). Power is the product of voltage —also known as potential differe...
a 10-nanosecond pulse has an energy content of only 10 joules. To put this in perspective, the average microwave oven in one second generates 1 kilojoule, or thousand joules of energy. It typically takes about 4 minutes to boil a cup of water, which corresponds to 240 kilojo...
yearly as new chips are developed and deployed. For the right price (more than $11,000), you could mine at 335TH for 16.0 joules per tera hash (16 watts at one trillion hashes per second).8There are much more affordable hardware versions, but the more you pay, the faster you can ...
If you're using an electric kettle rated at 2400 watts, that means it's consuming 2400 joules of electrical energy per second and putting (roughly) the same amount of energy into the water as heat each second as well. Divide 378,000 by 2400 and you find it takes the kettle about 160...
