Answer: A. when an electron in an atom is excited to a higher energy state

Explanation:

An absorption spectrum consists of dark lines on a visible background. The dark lines indicate the wavelength which is absorbed by the electron to jump from lower energy state to higher energy state.

Electron requires energy to jump to higher state. Specific wavelength is absorbed by the electron which appears as dark line. This wavelength is equivalent to energy difference between the two levels the electron is jumping.

Why is energy transferable?

disa [49]

Kinetic Energy. Energy is transferred from one object to another when a reaction takes place. Energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few. ... This energy would be in the form of motion, with the person lifting the blue ball to a higher level.

A locomotive is pulling 8 freight cars, each of which is loaded with the same amount of weight. The mass of each freight car (wi

nikitadnepr [17]

Answer:106560 N

Explanation:

Given

Let Tension between 2 and 3 car be $T_{23}$ and between 3 &4 is $T_{34}$

$T_{23}-T_{34}=ma$

mass of freight car =37,000 kg

acceleration of car $=0.48 m/s^2$

$T_{34}$ is accelerating all freights behind 3

therefore

$T_{34}=5\times ma$

$T_{34}=5\times 37000\times 0.48=88,800 N$

Thus

$T_{23}=T_{34}+ma$

$T_{23}=88,800+37000\times 0.48=88,800+17,760=106560 N$

What is black body radiation? Explain in detail.

tangare [24]

An object that absorbs all radiation falling on it, at all wavelengths, is called a black body. When a black body is at a uniform temperature, its emission has a characteristic frequency distribution that depends on the temperature. Its emission is called black-body radiation
