Answer:
<em>the centripetal acceleration will now be four times its initial value</em>
Explanation:
v=velocity
a=centripetal acceleration
r=radius to the center
take note tat a centripetal force is the force tat is needed to keep a body moving along a circular path
centripetal force is given by f=mv^2/r
a=v^2/r
v=v
wen v is doubled , we ave
2v
substituting into the previous equation of centripetal force
a=(/r
a=4^{2}/(r)
from the equation, is can be discovered that the centripetal acceleration will now be four times its initial value
Your answer is B :) because well the conditions are harsh.
Answer: Diffraction
Explanation:
-Diffraction, is basically the bending of waves as they move around an obstacle or through an opening. In both, the cases diffraction occurs. So as the waves hit the obstacle they will bend slightly around it.
The other options, for a better understanding why it's option A:
-Interference occurs when two waves at one point or another in the same medium, overlap
-Refraction of waves is the change in its direction when it moves from one medium to another. The other factors that change with refraction are the wavelength.
