4 0

Answer:

Explanation:

Mechanical energy = Kinetic energy + Potential energy

We shall calculate mechanical energy at different points of time .

Time        Kinetic energy         Potential energy      mechanical energy

   0                     0                                 4                                  4

    2                     2                                  2                                 4

     4                    4                                  0                                  4

      6                   2                                  2                                  4

     8                    0                                   4                                  4

     10                    2                                   2                                 4

and so on ........

Hence we see that total mechanical energy is constant at the value of 4

at all time .

Can spectrum colors be mixed
larisa86 [58]
Additive color mixing involves multiple sources of light with different colors in each source. Subtractive color mixing involves a single source of light with different colors absorbing various wavelengths of the color spectrum. Secondary colors of one system serve as the primary colors for the other.

Electron A falls from energy level X to energy level Y and releases blue light. Electron B falls from energy level Y to energy l
MrMuchimi

Answer: Transition from X to Y will have greater energy difference.

Explanation: For studying the energy difference, we require Planck's equation.

                                E=\frac{hc}{\lambda}

where, h = Planck's Constant

c = Speed of light

E = Energy

\lambda = Wavelength of particle

From the equation, it is visible that the energy and wavelength follow inverse relation which means that with low wavelength value, energy will be the highest and vice-versa.

As electron A falls from X-energy level to Y-energy level, it releases blue light which has low wavelength value (around 470 nm) which means that it has high energy.

Similarly, Electron B releases red light when it falls from Y-energy level to Z-energy level, which has high wavelength value (around 700 nm), giving it a low energy value.

Energy Difference between X-energy level and Y-energy level will be more.
