Answer:
4s
Explanation:
My assumption would be 4s since 25 going into 100 would be 4? hope that helped..
Answer:
0.003333 s to 0.000125s or from 3.33ms to 0.125ms wher m is for milli
1.1m to 0.04125 m
Explanation:
T= 1/f=
if f= 300Hz then T = 1/300 =0.003333 s
if f= 8000 then T= 1/8000 = 0.000125s
now v=f×wave length
or wavelength = speed/ frequency
when f = 300 Hz
wavelength = 330/300=1.1 m
wavelength = 330/8000 = 0.04125m
note : i have taken speed of sound as 330 m/s you can take any value given in between 330m/s to 340m/s
Answer:
Explanation:
Given: Density of blood = 1.03 × 10³ Kg/m³, Height = 1.93 m g = 9.8 m/s²
pressure at the brain is equal to atmospheric pressure. = Hydro-static
pressure(ρ₀)
∴ pressure of the foot = pressure of the brain(ρ₀) + ( density of blood × acceleration due to gravity × height)(ρgh)
Hydro-static pressure = pressure at the feet- pressure at the brain(ρ₀)
Hydro-static pressure (Δp) = (ρgh + ρ₀) - ρ₀ = ρgh
Hydro-static pressure = 1.03 × 10³ × 9.8 × 1.93 = 1.948 × 10⁴ Pa
∴ Hydro-static pressure ≈ 1.95 × 10⁴ Pa
Answer:
the answer is false :)
Explanation:
Science is based on theories and tests, if someone has a theory they will test and if it is correct yippie! and if it isn't they will redo the test over until they get it correct or unless it is unsolvable.
