Answer:
Explanation:
The former is the case of constructive interference and the later case relates to destructive interference.
For listener, path difference is the separation of loudspeaker as listener is not standing in between the speaker.
If λ be the wave length
For constructive interference
19 = n λ
For destructive interference
29 = (2n+1) λ / 2
= n λ + λ / 2
= 19 + λ / 2
10 = λ / 2
λ = 20 cm
= 0. 20 m
<>"And, water is called the "universal solvent" because it dissolves more substances than any other liquid. This is important to every living thing on earth. It means that wherever water goes, either through the ground or through our bodies, it takes along valuable chemicals, minerals, and nutrients."<>

Answer:
Venus
Explanation:
To know the correct answer to the question, we shall determine the weight of the space probe on each planet to see which will correspond to 3560 N.
This is illustrated below:
For Mercury:
Mass = 400 Kg
Gravitational force = 3.7 N/Kg
Weight =?
Weight = mass × gravitational force
Weight = 400 × 3.7
Weight = 1480 N
For Venus:
Mass = 400 Kg
Gravitational force = 8.9 N/Kg
Weight =?
Weight = mass × gravitational force
Weight = 400 × 8.9
Weight = 3560 N
For Earth:
Mass = 400 Kg
Gravitational force = 9.8 N/Kg
Weight =?
Weight = mass × gravitational force
Weight = 400 × 9.8
Weight = 3920 N
For Neptune:
Mass = 400 Kg
Gravitational force = 11 N/Kg
Weight =?
Weight = mass × gravitational force
Weight = 400 × 11
Weight = 4400 N
For Jupiter:
Mass = 400 Kg
Gravitational force = 23.1 N/Kg
Weight =?
Weight = mass × gravitational force
Weight = 400 × 23.1
Weight = 9240 N
SUMMARY:
Planet >>>>>> Weight
Mercury >>>> 1480 N
Venus >>>>>> 3560 N
Earth >>>>>>> 3920 N
Neptune >>>> 4400 N
Jupiter >>>>>> 9240 N
From the above calculations, we can see that the weight of the space probe (i.e 3560 N) correspond to the weight on venus (i.e 3560 N)
