The question is not well presented.
There is ______ shift in sound frequency for observers towards whom the source is approaching.
Answer:
The gap should be filled with an apparent upward
Explanation:
The Doppler effect (also referred to as the Doppler shift) is the difference in frequency of a wave when related to an observer who has a relative movement to the wave source
The Doppler effect can be observed to occur with all types of waves - most notably water waves, sound waves, and light waves
The Doppler effect describes sound as an effect which is produced from a moving source of wave.
According to the Doppler effect;
When the source of waves in which there is an apparent upward shift in frequency for observers towards whom the source is approaching.
Explanation:
The frequency of a spring is:
f = 1/(2pi) sqrt(k / m)
If m doubles, then f decreases by a factor of 1/sqrt(2).

Explanation:
v= (f) x ( lambda)
1.7 ms^-1/12.05 m = f =o.14 hz
Explanation:
In the parallel combination, the equivalent resistance is given by :
4. When three 150 ohms resistors are connected in parallel, the equivalent is given by :
5. Three resistors of 20 ohms, 40 ohms and 100 ohms are connected in parallel, So,
Hence, this is the required solution.
