Answer:
Therefore the terminal velocity = 1.45 m/s
Explanation:
Terminal velocity: Terminal velocity is the highest velocity of an object when it falls from rest trough a media.
= terminal velocity
w = weight of the object = mg
= drag coefficient=0.80
A= frontal area
= media density = 1.2 kg/m³
m = mass = 8 kg
g= acceleration due to gravity = 9.8 m/s²
Front area = length× breadth
= (18×47)cm²
=846 cm²
Therefore the terminal velocity
=1.45 m/s
Therefore the terminal velocity = 1.45 m/s
Light can be seen as an electromagnetic wave.
What happens when two waves, with the same frequency, superpose is called interference.
If at a certain point two waves arrive both with a crest, we have constructive interference and the amplitudes sum up, reaching the maximum value, resulting in bright spots.
If at a certain point one of the waves arrives with a crest and the other wave arrives with a trough, we have destructive interference, and the two amplitudes cancel out, resulting in dark spots.
Therefore, t<span>he dark bands on the wall are from destructive interference.</span>
Answer:
Regeneration means that an organism regrows a lost part, so that the original function is restored.
