To find the pressure with a given data for the height, you are asked to get the hydraulic pressure. Hydraulic pressure has the following formula:
P = density*acceleration due to gravity*height
Assume that the density of seawater is the same as that for pure water,density = 1000 kg/m^3.
P = 1000 kg/m3*9.81m/s2*9100m
P = 89271000 Pascals or 89.271 megapascals
Answer:
3.6ft
Explanation:
Using= 2*π*sqrt(L/32)
To solve for L, first move 2*n over:
T/(2*π) = sqrt(L/32)
Next,eliminate the square root by squaring both sides
(T/(2*π))2 = L/32
or
T2/(4π2) = L/32
Lastly, multiply both sides by 32 to yield:
32T2/(4π2) = L
and simplify:
8T²/π²= L
Hence, L(T) = 8T²/π²
But T = 2.1
Pi= 3.14
8(2.1)²/3.14²
35.28/9.85
= 3.6feet
Answer:
t = 1.6667 10⁻⁷ m
Explanation:
When light falls on a thin film on the surface we have two phenomena
- a change in phase when the beam passes to a medium with a higher index
- on the other hand, in the wavelength, due to the refractive index of the medium
λ = λ₀ / n
The second ray reflected from the other surface has no phase change
So the path difference between the two rays for destructive interference is
2t = m λ₀ / n
t = m λ₀ / 2n
Let's calculate
t = 1 500 10⁻⁹ / 2 1.50
t = 166.67 10⁻⁹ m
t = 1.6667 10⁻⁷ m
Answer: no
Explanation: you add the right side and if it equals the same as the left side then it is balanced.
