How many joules are in a hertz
Did you know?
Web6,000 joules -To find this answer, remember that 1 watt = 1 joule/s, so a 100-watt light bulb uses 100 joules of energy per second. In 1 minute, it uses 60 ( 100 = 6,000 joules of energy. Click the card to flip 👆 1 / 22 Flashcards Learn Test Match Created by learjet323 Terms in this set (22) WebTo convert 1 Watt Hour to Joules you have to multiply 1 by 3600, since 1 Watt Hour is 3600 Joules. The result is the following: 1 Wh × 3600 = 3600 J. 1 Wh = 3600 J. We conclude that one 1 Watt Hour is equivalent to three thousand six hundred Joules:
WebJoules to watts calculator Watts to joules calculation. The energy E in joules (J) is equal to the power P in watts (W), times the time period t in seconds (s): E (J) = P (W) × t (s) WebThe joule (symbol J, also called newton meter, watt second, or coulomb volt) is the SI unit of energy and work. The unit is pronounced to rhyme with "tool", and is named in honor of the physicist James Prescott Joule (1818-1889). Metric conversions and more.
Web17 mrt. 2015 · You have two useful formulas. E = hf, where h is Planck's constant, and f is the frequency of the photon. The other formula is f λ = c, where λ is the wavelength of the photon and c is the speed of light. Since f = c λ, we can write E = hc λ = 6.626 ×10⁻³⁴J⋅s ×2.998 ×10⁸m⋅s⁻¹ 5.00× 10⁴× 10⁻⁹m = 3.97× 10⁻²¹J Answer link Michael Mar 17, 2015 WebCalculate the frequency in hertz, the energy in joules, and the energy in electron volts of an X-ray photon.
