166x5.75= 954.5 meters in 5.75 seconds.
answer: 340 m/s
explanation: in this instance, the sound wave travels 340 meters in 1 second, so the speed of the wave is 340 m/s. remember, when there is a reflection, the wave doubles its distance. in other words, the distance traveled by the sound wave in 1 second is equivalent to the 170 meters down to the canyon wall plus the 170 meters back from the canyon wall.
Power = work / time --> time = work / power = 3600 J / 275 watts = 13.1 seconds.
Make me brainliest plz
Answer:
Body dysmorphic disorder is a mental disorder in which you can't stop thinking about one or more perceived defects or flaws in your appearance — a flaw that, to others, is either minor or not observable. But you may feel so ashamed and anxious that you may avoid many social situations.
Explanation:
Answer:
viscosity = 0.051725 N/m-s
Explanation:
Given data
diameter = 0.3 m
u(r) = 0.4/r - 1000r m/s
diameter d1 = 2 cm = 0.02 m
diameter d2 = 4 cm = 0.04 m
rotation = 500 rpm
power = 1 w
to find out
fluid viscosity
solution
we have given
u(r) = 0.4/r - 1000r m/s
du/dr = -0.4/r² + 1000
here r = 0.3 /2 = 0.01 m
du /dr = -0.4/(0.01)² + 1000
du/dr = 5000
and
so velocity is
force = viscosity ( 2π×r×L) du/dr
0.026 / 0.02 = viscosity ( 2π× 0.02×0.04) 5000
viscosity = 0.051725 N/m-s
