Answer:
The possible range of wavelengths in air produced by the instrument is 7.62 m and 0.914 m respectively.
Explanation:
Given that,
The notes produced by a tuba range in frequency from approximately 45 Hz to 375 Hz.
The speed of sound in air is 343 m/s.
To find,
The wavelength range for the corresponding frequency.
Solution,
The speed of sound is given by the following relation as :

Wavelength for f = 45 Hz is,


Wavelength for f = 375 Hz is,


So, the possible range of wavelengths in air produced by the instrument is 7.62 m and 0.914 m respectively.
<h3>During a chemical reaction,one ore more new substances forwed</h3>
Answer:
The right solution is "126 Psi".
Explanation:
The given values are:
P₁ = 130 psig
i.e.,
= 
= 
or,
= 
Z₂ = 10ft
= 3.05 m
= 1000 kg/m³
According to the question,
Z₁ = 0
V₁ = V₂
As we know,
⇒ 
On substituting the values, we get
⇒ 
⇒ 
⇒ 
i.e.,
⇒ 
⇒ 
<span>It is true that all nuclear energy results in
the rapid release of energy, such as in atomic bombs. <span>A process wherein the atom’s nucleus
is further divided into two nuclei, that is, fission products, is called
nuclear fission. This happens when the nuclei of radioactive elements (e.g.
Uranium or Plutonium isotopes) are able to attract neutrons. Because these
isotopes’ nuclei are unstable, an addition to their energy causes them to
divide into new pieces of neutron. In nuclear reactors, fission occurs when the
power plant gathers heat from a steam in a physical process. Nuclear reactors
are designed to sustain nuclear chain reactions.</span></span>
