The equation to calculate the amount of energy used by an appliance is: Energy (kWh) = Power (kW) x Time (hours). Multiply the power consumption of the appliance in kilowatts by the number of hours it's used to find the total energy consumed in kilowatt-hours.

How can one calculate the amount of energy lost in a system?

To calculate the amount of energy lost in a system, you can use the formula: Energy lost Initial energy - Final energy. This means subtracting the final energy from the initial energy to find the difference, which represents the amount of energy lost.


What is the energy of a photon of 325nm?

The energy of a photon is determined by the equation E = hf, where E is energy, h is Planck's constant (6.626 x 10^-34 J s), and f is the frequency of the photon. First, calculate the frequency of the photon using the speed of light equation, c = λf. Then, substitute the frequency into the energy equation to find the energy of the photon.


How do you find the wavelength using binding energy?

To find the wavelength using binding energy, you can use the equation E=hc/λ, where E is the binding energy, h is the Planck constant, c is the speed of light, and λ is the wavelength. Rearrange the equation to solve for the wavelength: λ=hc/E. Plug in the values for h, c, and the binding energy to calculate the wavelength.


What is the method to find the energy delivered by each battery?

To find the energy delivered by each battery, you can multiply the voltage of the battery by the amount of charge it delivers. This will give you the energy in joules.


How is matter related to energy?

Matter and energy are related through Einstein's famous equation, E=mc^2, which demonstrates that matter can be converted into energy and vice versa. This equation explains that energy and mass are essentially two forms of the same thing. When matter is converted into energy, the amount of energy produced is directly proportional to the amount of matter lost.

Total amount of energy an object has?

The total amount of energy an object has is its sum of kinetic energy (energy of motion) and potential energy (stored energy). This can be calculated using the equation: total energy = kinetic energy + potential energy.


How can one find energy with wavelength?

One can find energy with wavelength by using the equation E hc/, where E represents energy, h is Planck's constant, c is the speed of light, and is the wavelength of the light. This equation shows the relationship between energy and wavelength in electromagnetic radiation.

The amount of power derived from a device or system is its?

That amount is always less than the energy you put into the system. Divide the amount of useful energy you get from a system by the amount of energy you put into it, and you find the system's 'efficiency'.

How do you know how many amps an appliance is using?

If the appliance tells you how many watts it's supposed to use you can buy a watt-meter to measure how many watts the appliance is using buy plugging in the meter into the wall and then plugging the appliance into the meter. A popular brand is "Kill A Watt", it meter can be bought on E-bay for under $25.

What does E equals mc2 calculate?

E=MC2 means: Energy (E) = Mass (M) times The Speed of Light (C) squared. This basically tells us that energy and matter are the same. A small amount of matter can be converted into a large amount of energy. So using the equation E=MC2 we can find out that 0.00000000001 gram of mass, will equal nine hundred thousand joules of energy: 0.00000000001g x (3x108) = 900,000j
