A combination of one hydrogen atom and 2 oxygen atoms.
Answer:
1.57 kg
Explanation:
Let the mass of block is m.
Spring constant, K = 9.4 N/m
Amplitude, A = 15.5 cm
y = A/2
v = 32.8 cm/s = 0.328 m/s
The velocity of the particle executing SHM is given by

where, ω is the angular frequency of SHM.


0.328 = ω x 0.866 x 0.155
ω = 2.45 rad/s
Now the angular frequency is given by

K = mω²
9.4 = m x 2.45 x 2.45
m = 1.57 kg
The characteristics of electromagnetic radiation include amplitude (brightness), wavelength, frequency, and period. We have shown that the frequency of a light wave is proportional to its energy by the equation E = h v or E=hnu
so
Radiation with a wavelength of 8.1 X 10^-8 m has the highest energy
<h3>Why is it called electromagnetic?</h3>
- When a charged particle, like an electron, changes its velocity—that is, when it is accelerated or decelerated—electromagnetic radiation is created. The charged particle is responsible for losing the energy of the electromagnetic radiation that is thus created.
- Since the electric and magnetic fields are oscillating, the waves of energy are known as electromagnetic (EM). They are categorized by scientists based on their frequency or wavelength, from high frequency to low frequency (short to long wavelength).
