What is the energy in joules and in eV of a photon in a radio wave from an AM station that has a 1305 kHz broadcast frequency? What is the energy in joules and eV of a photon in a radio wave from an AM station that has a 840...
Question: What is the enegy (in Joules) of a photon with a wavelength of 201 nm? The energy of Light: Different theories have been proposed regarding the energy from light. Some state that light travels in the form of waves, while some state that light travels in the form o...
What is the kinetic energy, in joules, of this baseball when it is thrown by a major league pitcher at 95.0 mi/h?Kinetic EnergyThe mechanical energy of an object is the energy that it possesses due to its motion (speed). An obj...
the electrons in each atom are in constant motion, so the atom has a small vibration. Nonetheless, its position remains fixed, which is why solid particles have low kinetic energy.
Joule can be used to measure electrical, mechanical, thermal, or other types of energy. The chemical reaction released 1000 joules of thermal energy. 4 Watt Watt can describe how fast energy is consumed or generated. The generator produces 500 watts of power every hour. 7 Joule Joule, in te...
What is the Energy Difference(ΔE)between the Quantum States of the Tyrian Purple molecule responsible for the Visible absorption band? Upper Electronic Quantum States Lower Electronic Quantum States Show Work! 590nmΔE= Joules (color1) ...
The formula for the energy of motion is: KE=0.5×m×v2 where KE is kinetic energy in joules, m is mass in kilograms and v is velocity in meters per second.Force and Work Newton's three laws of motion form the basis for classical physics. The first law defines force as that which ca...
Light, another form of energy, has no mass. Therefore, no term exists for the specific energy of light. In discussing chemical energy, it is often more useful to be concerned with specific measurements on a molecular basis instead of a mass basis. A chemist may use joules per mole (J/mo...
Energy is best defined as “the capacity for doing work”. Electricity is but one of many forms of energy. Other familiar forms of or descriptions of energy
It is also equal to one watt of power emitted or dissipated for one second, or watt second (Ws). In various applications, British thermal units (BTU) are used to express the unit for energy. One BTU is equal to approximately 1,055 joules. One joule is equal to: 1× 107 erg (...
