In everyday language, the speaker uses onomatopoeia, short sentences, repetitions, redundancies, among others. In turn, technical language is used by scientific and professional people.
Answer:
f' =1064.1025 Hz
Explanation:
We know that from doppler's effect

f'= observed frequency
f= actual frequency =1000 Hz
v= velocity of sound waves = 332 m/s
v_o= velocity of observer =0
v_s= velocity of source. ( let velocity of car be 20 m/s)
therefore,

f' =1064.1025 Hz
