The frequency of the wave = 400/s
<h3>Further explanation</h3>Given
v=200 m/s
λ=0.5 m
Required
The frequency of the wave
Solution
Frequency (f): number of waves in one second
The frequency is inversely proportional to the wavelength

Here in all nuclear reactions we can say that mass conservation and charge conservation is always true
Here iron nuclei smashed into lead nuclei and then a new nuclei will form which will released along with a neutron
Now in this reaction mass and charge will remain conserved
mass number of iron + mass number of lead = mass number of new nuclei + mass number of neutron
58 + 208 = x + 1
x = 265
so the new nuclei formed will have mass number A = 265
now we will use charge conservation
Number of protons in iron + number of protons in lead = number of protons in new nuclei + number of protons in neutron
26 + 82 = z + 0
z = 108
so the new nuclei will form with atomic number z = 108 and mass number A = 265
If we refer periodic table to find such atom we will see that this is
so the new nuclei formed is
