I can't remember how to solve this kind of problem.
So, in desperation, I take a hard look at the units.
I do remember that electric field is measured in volts per meter,
and 1 volt/meter means 1 newton/coulomb. And there it is !
The problem has a quantity of [newtons] and a quantity of [coulombs]
in it. If I divide those, the quotient will be [newton/coulomb], and THAT's
electric field strength !
(3.0 x 10⁻⁹ N) / (1.25 x 10⁻¹⁹ C)
= 2.4 x 10¹⁰ N / C
= 2.4 x 10¹⁰ volts/meter .

Why is it dangerous*btw.....And because you can easily crash into another vehicle also because it's just plain stupid to jump anyway ...
Answer:
v = 8.4 m/s
Explanation:
The question ays, "A longitudinal wave has a frequency of 200 Hz and a wavelength of 4.2m. What is the speed of the wave?".
Frequency of a wave, f = 200 Hz
Wavelength = 4.2 cm = 0.042 m
We need to find the speed of the wave. The formula for the speed of a wave is given by :

So, the speed of the wave is equal to 8.4 m/s.
