The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic systems. The law of conservation of energy states that the total energy of an isolated system is constant; energy can be transformed from one form to another, but can be neither created nor destroyed.
The smallest unit that makes up matter is atom. The correct option is A.
The atom is the smallest component of matter. The fundamental units of matter, or atoms, cannot be further divided without losing their essentialcharacteristics.
They have an orbitally arranged nucleus of protons and neutrons that surrounds them. Molecules, which are collections of atoms bound together, are created when various atom kinds are combined.
On the other hand, cells, which are made up of different molecules, are the fundamental structural and functional units of living things.
Protons are subatomicparticles that can be found in the atom's nucleus, however they are not the tiniest piece of matter.
Thus, the correct option is A.

The frequency and wavelength of the sound wave with the given time period and speed are 500Hz and 0.688m respectively.
Period is simply the time taken for a complete cycle of vibration to pass a given point. Frequency is expressed as;
f = 1/T
Where f is frequency and T is period of time.
Given that;
f = 1/0.002s
f = 500s⁻¹
f = 500Hz
Wavelength is simply the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.
From the wavelength, frequency and speed relation,
λ = s ÷ f
Where λ is wavelength, s is speed and f is frequency.
Given that;
λ = s ÷ f
λ = 344m/s ÷ 500s⁻¹
λ = 0.688m
Therefore, the frequency and wavelength of the sound wave with the given time period and speed are 500Hz and 0.688m respectively.

Answer:
Given
Time (T) = 0.002 sec
Velocity(V) = 344 m/s
Frequency (f) = ?
Wavelength (w) = ?
Explanation:
We know that
Frequency (f) = 1/ t
= 1/ 0.002
= 500 hertz
Now
wavelength = V/f
= 344/500
= 0.688 m
