Due to the moon's gravitational force and inertias counterbalance.
Answer:
a) m = 10 and b) λ = 3.119 10⁻⁷ m
Explanation:
In the diffraction experiments the maximums appear due to the interference phenomenon modulated by the envelope of the diffraction phenomenon, for which to find the number of lines within the maximum diffraction center we must relate the equations of the two phenomena.
Interference equation d sin θ = m λ
Diffraction equation a sin θ = n λ
Where d is the width between slits (d = 0.2 mm), a is the width of each slit (a = 0.02 mm). θ is the angle, λ the wavelength, m and n are an integer.
Let's find the relationship of these two equations
d sin θ / a sin θ = m Lam / n Lam
The first maximum diffraction (envelope) occurs for n = 1, let's simplify
d / a = m
Let's calculate
m = 0.2 / 0.02
m = 10
This means that 10 interference lines appear within the first maximum diffraction.
b) let's use the interference equation, remember that the angles must be given in radians
θ = 0.17 ° (π rad / 180 °) = 2.97 10⁻³ rad
d sin θ = m λ
λ = d sin θ / m
λ = 0.2 10⁻³ sin (2.97 10⁻³) / 2
λ = 3.119 10⁻⁷ m

,
,
,
,
, 
Explanation:
Looking at the diagram uploaded we see that there are two forces acting along the x-axis on the fixed support
These force are 400 N and
[ i.e the reactive force of 400 N ]
Hence the sum of forces along the x axis is mathematically represented as

=> 
Looking at the diagram uploaded we see that there are two forces acting along the y-axis on the fixed support
These force are 500 N and
[ i.e the force acting along the same direction with 500 N ]
Hence the sum of forces along the x axis is mathematically represented as

=> 
Looking at the diagram uploaded we see that there are two forces acting along the z-axis on the fixed support
These force are 600 N and
[ i.e the reactive force of 600 N ]

Answer:
the velocity of the water flow is 7.92 m/s
Explanation:
The computation of the velocity of the water flow is as follows
Here we use the Bernouli equation
As we know that

= 7.92 m/s
Hence, the velocity of the water flow is 7.92 m/s
We simply applied the above formula so that the correct value could come
And, the same is to be considered
