Answer:
Explanation:
Given:
length of unstrained spring,
mass attached to the spring,
length of the spring after hanging the mass,
energy to be stored in the spring,
<u>The length of the spring stretched after hanging the mass:</u>
<u>Therefore the stiffness constant of the spring:</u>
where
F = is the force to which the spring is subjected for the corresponding change in length .
here,
<u>As we know that the spring potential energy is given as:</u>
where
extension in the length of the spring
<u>So the total length of the spring when it stores 10 J energy:</u>
Answer:
θ = 34.77°
Explanation:
From diffraction equation:
where,
m = order of diffraction
λ = wavelength of light used
d = slit separation
θ = angle
Therefore, for initial case:
m = 2
λ = 600 nm = 6 x 10⁻⁷ m
d = slit seperation = ?
θ = angle 20°
Therefore,
Now, for the second case:
m = 5
λ = 600 nm = 6 x 10⁻⁷ m
d = slit seperation = (1.5)(3.5 x 10⁻⁶ m) = 5.26 x 10⁻⁶ m
θ = angle = ?
Therefore,
<u>θ = 34.77°</u>
