2. in a thunderstorm at 20.0°c, karen sees a bolt of lightning and hears the thunderclap 3.00 s later. how far from karen did the lightning strike? show your work.

i don't want answer just the formula on how to solve it. you!

1029 m

In a thunderstorm the thunderclap is always heard after some seconds of lightning because speed of light and speed of sound is different in the air though these both incident took place at the same time.

Sound in air travels at approximately 343 m/s at 20°C

The speed of light in air is to 3 x 10⁸ m/s at 20°C

Formula to use

distance = speed x time

              = 3 x 343

              = 1029 m

found in the nucleus

has mass of one amu

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
