By definition we have that the force of the spring is given by:
F = -k * deltax
Where,
k: spring constant
deltax = elongation
Let's clear k:
k = -F / delta x
k = mg / delta x
delta x = 0.119 -0.1 = 0.019m
Substituting the values:
k = (1) * (9.81) / (. 019)
k = 516 N / m
Answer:
<span> the spring constant of this spring is
</span> k = 516 N / m
Answer:
Explanation:
At the point when light is vertically polarized is incident on the polarizer whose axes are situated at angle points the intensity power in the wake of going through all the polarisers is given by the Malus law, applied threefold for every one of the three axes.
The heading of the direction of the polarization is equivalent to the pivoted axes of the polarizer provided that light is an electromagnetic wave, its course of polarization is therefore controlled by the electric field part.
∴
a)
When sheet A is removed, the transmitted light goes through B, at 30°.
b)
When B is removed, No light passes since the axis of A and the axis of C are perpendicular to each other.
c)
When C is removed, the intensity is indeed zero since the axes are aligned and adjusted at 90° to one another.
The speed of sound is 100 divided by 0.30
So that makes it 333.333333333333 second per meter
