As the speed of light is constant in vacuum the question is not correctly framed. As per postulate of Special Theory of relativity the speed of light in vacuum is constant for all observers, …

When an electron jumps from a high energy state to a lower state, what form does the emitted energy take? How does an atomic spectrum get affected by external electromagnetic fields? …

Simple Answer: c) The Potential Energy increases The choices for answers for this question suggest that we are only expected to consider this problem as simple charged objects moving …

270J From definition, Kinetic energy E_k=1/2mv^2. So in this case, E_k=1/2xx60xx3^2 =270J

the same to keep the temperature costant the emitted energy must be the same that the adsorbed energy . That that changes is the quality of radiation. Sunlight has a pick of light around 580 …

An adiabatic situation assumes no heat flow \mathbf (q) contributes to the internal energy U. The volume might have changed, but we don't know how, exactly. Even though we were given …

The electron volt (eV) is a unit of energy equal to approximately 1.6×10−19 joule (J). By definition, it is the amount of energy gained (or lost) by the charge of a single electron moved across an …

The wavelength is "42 m". c=lamda*nu, where: c is the speed of light, lamda, pronounced lamda, is the wavelength, and nu, pronounced noo, is the frequency. Given/Known c=3.00xx"10"^8" …

Besides other more powerful surface telescopes, HST in space provides data from electromagnetic-wave (including light) signals from space bodies that support scientific …

What is the definition of human anatomy and physiology? What is an example of each? Does anyone have any tips for how to study the names of bones, and the different parts of bones for …
