So we want to know the height Hi of the image if we know object distance Do=8 cm, image distance Di= 12 cm and the height of the object H0= 4 cm. The magnification formula is M=(Hi/H0)=(Di/Do). By multiplying the equation with H0 we get Hi=(Di/Do)*H0. Now we input the numbers and get: Hi=(12/8)*4=6 cm. So the height of the image Hi=6 cm.

f' = frequency observed by the police car after sound reflected from the vehicle and comes back to police car = 1250 Hz

f = frequency emitted by the police car  = 1200 Hz

V = speed of sound = 340 m/s

v = speed of vehicle = ?

frequency observed by the police car is given as

f' = f (V + v)/(V - v)

inserting the values in the above equation

1250 = 1200 (340 + v)/(340 - v)

v = 6.9 m/s

What causes the sound to have a lower volume when used in a carpeted room​
Viefleur [7K]

Answer:

Correct answer: The carpet material is soft, non-stick and diffuse and therefore absorbs waves.

Explanation:

The room is more acoustic if the walls and ceiling and floor are made of hard and polished material that reflects sound waves well while the carpeted room absorbs sound waves so it is less acoustic. The carpet material is soft, non-stick and diffuse and therefore absorbs waves.

God is with you!!!
