Answer:
C. identity of the element
The specific amount of energy emitted when electrons jump from excited states to the ground state refers to emission spectrum. The energy is emitted in the form of photons, and the photons have very specific wavelengths (energy) that correspond to the energy gaps between the excited states and the ground state. The specific wavelengths of light emitted are referred to as the "emission spectrum," and each element produces a different emission spectrum. Thus, this emitted energy can be used to identify the element from which your sample was taken.

Answer:
Explanation:
Volume of cube=side³
=2*2*2
=8 cm³
Mass of cube=40g
Its density=mass/volume
=5g/cm³
which differs the value given in the text hence it is not gold and u should not bye it...
Instead u should call the police for arresting the person lol...
Answer:
It is perceived as louder.
Explanation:
Amplitude affects the loudness of sound.
Frequency and wavelength affect the pitch of the sound.
