Answer:
The bird appears farther
Explanation:
This is because as the light from the bird travels into the water which has a higher refractive index than air, light rays from the kingfisher bird bend towards the normal at the water surface and thus enter the eye of the scuba diver. Now, if we project the light rays from the eyes of the scuba diver into the air, we see that they appear to come from a point farther than that of the actual kingfisher bird perched on the branch.
<u>So, the bird appears to the diver to be farther from the surface than the actual bird</u>
Answer:
The work done required is
Explanation:
Given that,
Stretch spring = 2 cm
Stretch spring = 1 cm
We need to calculate the work done
Using formula of work done
Put the value into the formula
.....(I)
We need to calculate the work done
Using formula of work done
Put the value into the formula
.....(II)
We need to calculate the work done
Using equation (I) and (II)
Hence, The work done required is
So first things first its c. because when two plates collide it causes a earthquake so u can rule those out and of course no not volcano so that's it u only have c left as your answer choice.
