Two students push a heavy crate across the floor. John pushes with a force of 185 N due east and Joan pushes with a force of 165
N at 30∘north of east. What is the resultant horizontal force on the crate?
1 answer:
Answer:
327.894 N
Explanation:
We have given two forces Jhon pushes with a force of 185 N in east direction and Joan pushes with a force of 165 N at 30° north of east which is clearly shown in figure
We fave to find the total horizontal force
So total horizontal force will be =327.894 N ( total horizontal force will be sum of force in the east direction and horizontal component of the force in north- east direction)

Answer:
λ = 5.656 x 10⁻⁷ m = 565.6 nm
Explanation:
Using the formula of fringe spacing from the Young's Double Slit experiment, which is given as follows:
where,
λ = wavelength = ?
Δx = fringe spacing = 1.6 cm = 0.016 m
L = Distance between slits and screen = 4.95 m
d = slit separation = 0.175 mm = 0.000175 m
Therefore,
<u>λ = 5.656 x 10⁻⁷ m = 565.6 nm</u>
