Answer:
The system will take approximately 0.255 seconds to reach the (new) equilibrium position.
Explanation:
We notice that block-spring system depicts a Simple Harmonic Motion, whose equation of motion is:
(1)
Where:
- Position of the mass as a function of time, measured in meters.
- Amplitude, measured in meters.
- Spring constant, measured in newtons per meter.
- Mass of the block, measured in kilograms.
- Time, measured in seconds.
- Phase, measured in radians.
The spring is now calculated by Hooke's Law, that is:
(2)
Where:
- Gravitational acceleration, measured in meters per square second.
- Deformation of the spring due to gravity, measured in meters.
If we know that ,
and
, then the spring constant is:
If we know that ,
,
,
and
, then (1) is reduced into this form:
(1)
And now we solve for . Given that cosine is a periodic function, we are only interested in the least value of
such that mass reaches equilibrium position. Then:
The system will take approximately 0.255 seconds to reach the (new) equilibrium position.
Answer:
So visible wavelength which is possible here is
416 nm and 693.3 nm
Explanation:
As we know that for normal incidence of light the path difference of the reflected ray is given as
so here we can say that for maximum intensity condition we will have
so we have
now for visible wavelength we have
for N = 1
for N = 2
for N = 3
