Answer is C: Ability to see three-dimensional images of the surfaces of object
Explanation:
To enable the technician see fractures and broken particles in a better resolution as the SEM sees the peaks and valley of the structure.
Zero acceleration means the object's velocity is not changing.
So the object is moving in a straight line, at a constant speed
that could be anything (including zero) as long as it's constant.
Answer:
Part a)
T = 3.96 s
Part b)
T = 1.98 s
Part c)
T = 2.8 s
Explanation:
As we know that time period of spring block system is given as
![T = 2\pi\sqrt{\frac{m}{k}}](https://tex.z-dn.net/?f=T%20%3D%202%5Cpi%5Csqrt%7B%5Cfrac%7Bm%7D%7Bk%7D%7D)
T = 2.8 s
Part a)
If the mass of the block attached is doubled
then we will have
![T' = 2\pi\sqrt{\frac{2m}{k}}](https://tex.z-dn.net/?f=T%27%20%3D%202%5Cpi%5Csqrt%7B%5Cfrac%7B2m%7D%7Bk%7D%7D)
![T' = \sqrt2 T](https://tex.z-dn.net/?f=T%27%20%3D%20%5Csqrt2%20T)
![T' = 3.96 s](https://tex.z-dn.net/?f=T%27%20%3D%203.96%20s)
Part b)
If the spring constant is doubled
then we have
![T' = 2\pi\sqrt{\frac{m}{2k}}](https://tex.z-dn.net/?f=T%27%20%3D%202%5Cpi%5Csqrt%7B%5Cfrac%7Bm%7D%7B2k%7D%7D)
![T' = \frac{T}{\sqrt2}](https://tex.z-dn.net/?f=T%27%20%3D%20%5Cfrac%7BT%7D%7B%5Csqrt2%7D)
![T' = 1.98 s](https://tex.z-dn.net/?f=T%27%20%3D%201.98%20s)
Part c)
If the amplitude is halved but mass and spring constant will remain the same
so here we know that time period does not depends on Amplitude
so we will have
![T = 2\pi\sqrt{\frac{m}{k}}](https://tex.z-dn.net/?f=T%20%3D%202%5Cpi%5Csqrt%7B%5Cfrac%7Bm%7D%7Bk%7D%7D)
T = 2.8 s
