Answer:
The water shoots 15.31 m high above the street level.
Explanation:
The gauge pressure drives the motion of the water to whixhever height it will attain. The expression relating the gauge pressure to the height reached by the water, is
P = ρgh
P = Gauge Pressure = 150 kPa = 150,000 Pa
ρ = density of the fluid (water) = 1000 kg/m³
g = acceleration due to gravity = 9.8 m/s²
h = Height reached by the water = ?
150,000 = 1000 × 9.8 × h
h = (150000) ÷ 9800 = 15.306 = 15.31 m
Hope this Helps!!!
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.
Since we are only looking at the vertical height, we can use the free fall equation to find the height:
h = 0.5*g*t^2, where h is height in m, g is acceleration due to gravity (9.81 m/s^2), and t is time in seconds
h = 0.5*(9.81 m/s^2)*(3.7 s)^2
h = 67.15 m
Therefore, the 7th floor window is 67.15 m above ground level.
I believe it is an electromagnet
