Calculate joules of energy
WebJul 11, 2014 · λ = c f = 2.998 ×10⁸m⋅s⁻¹ 590 ×10³s⁻¹ = 508 m Wavelength from energy The formula is E = hc λ or λ = hc E, where h is Planck's constant. For example, what is the wavelength of a photon that has an energy of 3.36 × 10⁻¹⁹ J? λ = hc E = 6.626 ×10⁻³⁴J⋅s ×2.998 × 10⁸m⋅s⁻¹ 3.36 × 10⁻¹⁹J = 5.91 × 10⁻⁷ m = 591 nm Answer link WebEnergy consumption calculation. The energy E in kilowatt-hours (kWh) per day is equal to the power P in watts (W) times number of usage hours per day t divided by 1000 watts per kilowatt:

WebMar 17, 2024 · Your answer should always be stated in joules (J), which is the standard unit of measurement for kinetic energy. It is equivalent to 1 kg * m 2 /s 2. 2 Plug the mass and velocity into the equation. If you don't know the mass or velocity of the object, then you'll have to calculate it.
WebThe joule is used as a unit of work, energy, and heat, and is widely used in scientific applications. If... Named for English physicist James Prescott Joule, the joule (J) is one of the cornerstone units of the International metric system. The joule is used as a unit of work, energy, and heat, and is widely used in scientific applications. WebAug 2, 2024 · The value of Δ T is as follows: ΔT = Tfinal − Tinitial = 22.0°C − 97.5°C = −75.5°C If the sample gives off 71.7 cal, it loses energy (as heat), so the value of heat is written as a negative number, −71.7 cal. Substitute the known values into heat = mc Δ T and solve for c: −71.7 cal = (10.3 g) (c) (−75.5°C)
WebMost noteworthy, the unit of potential energy is joules (j) and one joule is equal to 1 (kgcdot m^ {2}/s^ {2}). To use it, follow these easy steps: In the absence of friction, mechanical energy is conserved: While acted on by earth's gravity would have 147.15 joules of potential energy, pe = 3kg * 9.81. WebIn classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per …
WebThe calculator uses certain formulas in performing the conversions; Calculation of Joules to watts P (W) = E (J) / t (s), which means that the power in watts is calculated by dividing the energy in joules by the time in seconds. It can also be expressed as; Watt = Joule / second or W =J / s For example;
