One kilojoules is equal to 1000 joules:1kJ = 1000JThe energy E in joules (J) is equal to the energy in kilojoules (kJ) times 1000:E(J) = E(kJ)× 1000ExampleConvert 4kJ to joules.The energy E in joules (J) is equal to 4 kilojoules times 1000:...
Watts to joules calculation formulaThe 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)Sojoules = watts × secondsorJ = W × sExampleWhat is the energy consumption of an electrical circuit that has ...
The conversion of joules (j) to moles (mol) commonly is calculated when measuring the energy changes during chemical reactions. A joule is a measure of energy; a mole is a measure of mass. If a chemical reaction produces a certain amount of energy, you can figure out how many moles of ...
If an electron is moved from a point at a potential of -61 V to a point at a potential of +61 V, how much work is done by the electric force, in units of joules? If a hydrogen atom has its electron in the n = 4 state, how much energy, in electron volts, is needed to ioni...
in the privacy of your home, never with other people. Repressing the urge to sing “Copacabana,” you miss the joy of sharing silly or sultry abandon with the people you love—and the people you may never get to love because inhibition robs you of the confidence needed to form a bond....
Multiply ν Planck's constant, h, by ν to get the value of E. In this example: E=6.626×10−34×3×1014=1.988×10−19J Cite This Article MLA Beck, Kevin. "How To Calculate Hertz To Joules"sciencing.com, https://www.sciencing.com/calculate-hertz-joules-7426215/. 13 December 202...
Convert 732 joules to calories. How could a pendulum be used to measure altitude? What are the units for the spring constant k? What is the formula for acceleration and how do you use it? What are the SI units of kinematic viscosity?
Yes, any unit of mass and distance can be multiplied as long as they are compatible units. For example, you can multiply kilograms (mass) by meters (distance) to get joules (energy), but you cannot multiply kilograms by seconds (time) as they are not compatible units. ...
Joules = 1.986 x 10-23/nm You may recognize the number 1.602 x 10-19as the charge of an electron in Coulombs. How to convert delta microns or nanometers to delta cm-1(inverse cm) Of course this is where it gets tricky, because the result depends on the absolute wavenumber, in other...
