<span>The correct option is: (A) Transverse Wave
Explanation:
Transverse wave is a wave in which the medium vibrates at right angles to the direction of its propagation.
In this case, consider the crowd as the medium and the perceived motion of the wave as the propagation. When the crowd moves up and down, the perceived wave be either from left to right or right to left. In either case, the crowd movement is perpendicular to the propagation of the wave. Imagine the crowd's up-down movement along y-axis and the perceived propagation of the wave along x-axis. Both axes are perpendicular to each other. Hence, the correct option is (A) Transverse wave.</span>
I believe your answer is d).
Hope you find this helpful! :)
Answer:
Explanation:
The Compton Shift in wavelength when the photons are scattered is given by the following equation:
(1)
Where:
is a constant whose value is given by , being the Planck constant, the mass of the electron and the speed of light in vacuum.
the angle between incident phhoton and the scatered photon.
We are told the maximum Compton shift in wavelength occurs when a photon isscattered through :
(2)
(3)
Now, let's find the angle that will produce a fourth of this maximum value found in (3):
(4)
(5)
If we want , must be equal to 1:
(6)
Finding :
Finally:
This is the scattering angle that will produce
If two forces "balance" each other, that means that they add up to zero.
THAT means that they must have exactly equal magnitudes and exactly opposite directions.
If you want to draw a picture of a pair of two balanced force vectors . . . .
1). Draw two arrows with exactly the same length.
2). Flip one of them over, so that it points in exactly the opposite direction compared to the first one.
3). Place them tail-to-tail.
Answer:
Magnetism would be the best way. This is because a magnet will attract the iron fillings from the sand
