Answer:
The range of characteristic frequencies of electromagnetic radiation that are readily absorbed and emitted by an atom. The atomic spectrum is an effect of the quantized orbits of electrons around the atom
Additional Facts:
- Atomic spectra can also be analyzed to determine the composition of objects
- The frequency depends on the difference in energy between the orbitals. Explaining this phenomenon was crucial to the development of quantum mechanics
- Occurs due to the fact are quantized at specific levels determined by the atomic number
Motion of things cause the energy such as the nuclear and the chemicals around temperature traveles
1) S.I. Unit for electric current = "Ampere"
2) S.I. Unit for resistance = "Ohm"
3) S.I. Unit for potential difference = "Volt"
Hope this helps!

18.6012339739 A
Explanation:
= Vacuum permeability = ![4\pi \times 10^{-7}\ H/m](https://tex.z-dn.net/?f=4%5Cpi%20%5Ctimes%2010%5E%7B-7%7D%5C%20H%2Fm)
L = Length of wire = 55 cm
N = Number of turns = 4000
I = Current
Magnetic field is given by
![B=\dfrac{\mu_0NI}{L}\\\Rightarrow I=\dfrac{BL}{\mu_0N}\\\Rightarrow I=\dfrac{0.17\times 0.55}{4\pi \times 10^{-7}\times 4000}\\\Rightarrow I=18.6012339739\ A](https://tex.z-dn.net/?f=B%3D%5Cdfrac%7B%5Cmu_0NI%7D%7BL%7D%5C%5C%5CRightarrow%20I%3D%5Cdfrac%7BBL%7D%7B%5Cmu_0N%7D%5C%5C%5CRightarrow%20I%3D%5Cdfrac%7B0.17%5Ctimes%200.55%7D%7B4%5Cpi%20%5Ctimes%2010%5E%7B-7%7D%5Ctimes%204000%7D%5C%5C%5CRightarrow%20I%3D18.6012339739%5C%20A)
The current necessary to produce this field is 18.6012339739 A
Answer:
D) wood rubbed against a rough surface feels hot
Explanation:
The heat is transferred from one form of energy (friction of the wood being rubbed against the surface) to another (heat energy).
