Answer:
d = m× λ⇒ d = λ ×m×l / x
= 630× m × 3×3m/ 45×
m
= 1.26×m
Explanation:
the above calculation is based on Young’s double slit experiment where the two slits provide two coherent light sources which results either constructive interference or destructive interference when passing through a double slit.
Answer:
Current in outer circle will be 15.826 A
Explanation:
We have given number of turns in inner coil
Radius of inner circle
Current in the inner circle
Number of turns in outer circle
Radius of outer circle
We have to find the current in outer circle so that net magnetic field will zero
For net magnetic field current must be in opposite direction as in inner circle
We know that magnetic field is given due to circular coil is given by
For net magnetic field zero
So
Answer:
Explanation:
From the concept of fluids mechanics we know that if a tank has a hole at the bottom, the equation that we need to use is:
Since we know gravity and its hight
