Answer:
Explanation: light waves against itself, which leads to internal interference of different wave component Which is also referred to as diffraction.
Diffraction causes beam of light to slowly spread out as it travels, so that some of the light will bend away from a straight line motion of the main part of the wave
Correct option B
Transverse waves are those waves whose particles vibrate perpendicular to the direction of wave.

Answer:
7500000 metres
Explanation:
1 kilometre = 1000 metres
so 7500 kilometres would equal to 7500000 metres
Answer:
The final velocity of the second player is 6.1 m/s.
Explanation:
The final velocity of the second player can be calculated by conservation of linear momentum (p):
(1)
Where:
: is the mass of the first football player = 110 kg
: is the mass of the second football player = 90 kg
: is the initial velocity of the first football player = 5.0 m/s
: is the initial velocity of the second football player = 0 (he is at rest)
: is the final velocity of the first football player = 0 (he stops after the impact)
: is the final velocity of the second football player =?
By solving equation (1) for we have:
Therefore, the final velocity of the second player is 6.1 m/s.
