The speed of sound really depends on the temperature and moisture in the air,
and the sound of the thunder doesn't necessarily travel straight from the lightning
to where you are. So we can't say exactly.
But if we use the nominal speed of 340 m/s, then 6 seconds means 2,040 meters,
or about 6,700 feet, or about 1.27 miles.
Answer:
Electromagnetic waves have crests and troughs similar to those of ocean waves. The distance between crests is the wavelength. The shortest wavelengths are just fractions of the size of an atom, while the longest wavelengths scientists currently study can be larger than the diameter of our planet!

Answer:
Explanation:
Given that
Mass , m = 78 kg
Initial velocity ,v= 19 m/s
Vertical height h= 4.4 m
Now by using energy conservation
Initial kinetic energy + Initial potential energy = Final kinetic energy +Final potential energy
KE₁ + U₁ = KE₂ + U₂
Therefore
Now by putting the values in the above equation
Therefore the final kinetic energy will be 10712.20 J.
