Explanation:
Why Cannot we hear an echo in a small room?
They can't hear an echo in small room because in it the sound can't be reflected back. For an echo of a sound to be heard,the minimum distance between the source of sound and the walls of the room should be 17.2 m.Obviously,in a small room echoes cannot be heard.
Answer:
Explanation:
Let +y is upward direction and backward be +x direction
then we have given data
From equation simple motion we find the time
So
To get the distance between the point the package ejected to the point it the ground.
Now we have to get the distance the helicopter travels during same interval
Now to get the distance between the package and helicopter when package hit the ground
Answer:
I don't think this is the right question
The characteristics of electromagnetic radiation include amplitude (brightness), wavelength, frequency, and period. We have shown that the frequency of a light wave is proportional to its energy by the equation E = h v or E=hnu
so
Radiation with a wavelength of 8.1 X 10^-8 m has the highest energy
<h3>Why is it called electromagnetic?</h3>
- When a charged particle, like an electron, changes its velocity—that is, when it is accelerated or decelerated—electromagnetic radiation is created. The charged particle is responsible for losing the energy of the electromagnetic radiation that is thus created.
- Since the electric and magnetic fields are oscillating, the waves of energy are known as electromagnetic (EM). They are categorized by scientists based on their frequency or wavelength, from high frequency to low frequency (short to long wavelength).
