Answer:
Correct answer: Wave's frequency f = 7.5 · 10¹⁴ Hz
Explanation:
Given: wavelength λ = 4.0 · 10⁻⁷ m and
ultraviolet wave's speed V = 3 · 10⁸ m/s
The formula for calculating frequency is:
f = V / λ = 3 · 10⁸ / 4.0 · 10⁻⁷ = 0.75 · 10¹⁵ = 7.5 · 10¹⁴ Hz
f = 7.5 · 10¹⁴ Hz

The electromagnetic radiation produced when a charged particle moves spirally in a magnetic field is called <span>synchrotron radiation. This phenomenon occurs due to the fact the particle is accelerated radially (due to the presence of the magnetic field), and every charged particle when it is accelerated emits electromagnetic radiation.</span>
Answer:
The pressure is
Explanation:
From the question we are told that
The gauge pressure at the mouth is
The radius of the column is
The speed of the liquid outside the body is
The area of the column is
The area inside the mouth
Generally according to continuity equation
=>
=>
=>
So
=>
=>
substituting values
Now the height of inside the mouth is
Now the height of the column is
Generally according to Bernoulli's equation
Now which is the density of water
is the gauge pressure of the atmosphere which is zero
So
