Answer:
y = 1.75 cm
Explanation:
In the double-slit experiment the equation for destructive interference is
d sin tea = (m + ½)
λ
let's use trigonometry to find the angle
tan θ = y / L
as all the experiment does not occur at small angles
tan θ = sin θ / cos θ = sin θ = y / L
we substitute
y = (m + 1/2 ) λ L / d
we calculate
y = (3 + ½) 500 10⁻⁹ 5.00 / 0.5 10⁻³
y = 1.75 10⁻² m
y = 1.75 cm
Answer:
Explanation:
Commonly area is a scalar quantity because there is no need of direction to define and also follow the algebrac summation. When we talk about vector there exist a frame of reference with a certain orogin
A nation's nominal GDP is $1.5 trillion with an inflation rate of 5%. ∴ Real GDP is 30 trillion.
<u>Explanation:</u>
Key Terms
GDP deflator: A measure of the level of prices of all new, domestically produced, final goods and services in an economy. It is calculated by computing the ratio of nominal GDP to the real measure of GDP.
real GDP: A macroeconomic measure of the value of the economy’s output adjusted for price changes (inflation or deflation).
nominal GDP: A macroeconomic measure of the value of the economy’s output that is not adjusted for inflation.
GDP deflator( inflation rate = 5% ) =
Inflation rate =
trillion
∴ Real GDP is 30 trillion.
Answer:
88.8 m/s= Speed of wave propagation in the required mode.(3 loops)
Explanation:
When there are 3 loops.
the total length = L = 3 λ /2
⇒ λ = 2 L / 3 = 2 ( 1.11 ) / 3 = 0.74 m
Velocity = v = f λ = (120)(0.74) = 88.8 m/s
