Answer:
37.42 m/s
Explanation:
We know that apparent frequency, is given by
where f is the given frequency in this case 392, V is the speed of sound in air which is given as 343 and is the speed of car which is unknown, \bar f is given as 440 Hz
The answer to this questions would be nuclear engineer. The overall career of engineering would require physics as engineers need to know how the overall mechanics of nature affect the way their structure is built.
Hope this helped :D
Neutron
Energy
Explanation:
From the nuclear fusion reaction above the products will be neutrons an energy release.
Nuclear fusion is the combination of small atomic nuclei into larger ones with the release of energy and some particles.
²₁H + ³₁H ⇒ ⁴₂He + ? + energy
To determine the products formed, we must understand that in nuclear reactions, the mass number and atomic number must be conserved.
Mass number = 5 - 4 = 1
Atomic number = 2 -2 = 0
The particle formed has a mass number of 1 and no atomic number. This is a neutron ¹₀n
²₁H + ³₁H ⇒ ⁴₂He + ¹₀n + energy
