Answer: A crest with an amplitude of 9 will form.
Explanation:
From super position principle, we know that when two waves move in same medium meet, then the net amplitude of the super imposed waves is sum of amplitudes of individual waves.
A constructive superposition takes place when crest meets crest and crest is formed of higher amplitude or trough meets trough and forms trough of higher amplitude. A destructive superposition takes place when crest of one meets trough of other -a crest or trough can form depending on the larger amplitude of either.
In the given situation, crest of wave X meets crest of wave Y. The amplitude of the super imposed wave would be = 5 + 4 = 9 and a crest would form.

Answer:
and
Explanation:
According to Coulomb's law, the magnitude of force between two point object having change and and by a dicstanced is
Where, is the permitivity of free space and
in SI unit.
Before dcollision:
Charges on both the sphere are and , d=20cm=0.2m, and N
So, from equation (i)
After dcollision: Each ephere have same charge, as at the time of collision there was contach and due to this charge get redistributed which made the charge density equal for both the sphere t. So, both have equal amount of charhe as both are identical.
Charges on both the sphere are mean of total charge, i.e
d=20cm=0.2m, and N
So, from equation (i)
As given that the force is repulsive, so both the sphere have the same nature of charge, either positive or negative, so, here take the magnitude of the charge.
The equation (ii) become:
From equation (iii)
So, the magnitude of initial charges on both the sphere are Coulombs and Colombs or .
Considerion the nature of charges too,
and
b. scattering.
c. reflection.
d. absorption.
The blue color of the sky is the result of scattering. The answer is letter B. it is specifically called the Rayleigh scattering. This blue color is the result of the incoming rays of the Sun into the earth’s atmosphere. It has he lowest wavelength which as we all see is the blue spectrum of light.
The electromagnetic waves with an energy of are likely X-rays.
The energy of an electromagnetic wave is related to its frequency and wavelength by the equation:
E = hf = hc/λ
where:
E = energy of the electromagnetic wave
h = Planck's constant ()
f = frequency of the electromagnetic wave
c = speed of light ()
λ = wavelength of the electromagnetic wave
Solving for λ:
λ = hc/E =
λ ≈
This corresponds to a wavelength of about 44 nanometers, which falls in the range of X-rays. Therefore, the electromagnetic waves with an energy of are likely X-rays.
