the first order bright band
A= 0.78
B= 0.11
C= 0.032
D= 0.62
The angle between the central bright band and the first order bright band is 0.78⁰, hence option A is correct.
According to the question:
A light with a wavelength of 410 nm falls on two slits separated by 0.03 mm,
So, the angle between the central bright band and the first order bright band is,
The angle will be, θ = λ/d radian
λ = 410 nm (410 × 10 ⁻⁹ m)
d = separation of slits (0.03 mm) or 0.03 × 10 ⁻³ m
θ =
= 0.01367 radian
= 0.01367 × (180/π)⁰
= 0.78⁰
Thus, the angle between the central bright band and the first order bright band is 0.78⁰, hence option A is correct.

B
Explanation:
B. Earthquakes and Volcanic Eruptions
C. Convection and The Moons Gravitational Pull
D. Convection and Gravity
Buoyant force is equal to the weight of the total amount of liquid displaced by an object when submerged partially or completely in the fluid. This means that if an object that has a volume of 2m³ has 50% (1m³) of its volume submerged in water, the buoyant force will be equal to the weight of 1 m³ of water, this is about 1000kg.
With this in mind, the buoyant force will be equal to the weight of the amount of fluid that has the same total volume as the object when the object is completely submerged, this is to say, it has its total volume under the fluid.
