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
Explanation:
A position versus time graph gives the position of an object at a certain point in time. The slope, also known as the derivative, will give the change in the position with respect to time. The slope will give you the instantaneous velocity of the object due to velocity being defined as the change in position over time
Answer:
Power plants generate electricity that is delivered to customers through transmission and distribution power lines. High-voltage transmission lines, such as those that hang between tall metal towers, carry electricity over long distances to meet customer needs.
