Answer:
One cycle for a sine wave is 360o or 2 radians. a) A sine wave with maximum amplitude at time t=0. The amplitude of a sine wave is maximum at the peak of the wave. Case 1: assuming that the wave is starting its cycle at t=0 then there is no phase shift for the wave at time t=0 without considering the amplitude...

Answer:
1) The absolute pressure equals = 96.98 kPa
2) Absolute pressure in terms of column of mercury equals 727 mmHg.
Explanation:
using the equation of pressure statics we have
![P(h)=P_{surface}-\rho gh...............(i)](https://tex.z-dn.net/?f=P%28h%29%3DP_%7Bsurface%7D-%5Crho%20gh...............%28i%29)
Now since it is given that at 6400 meters pressure equals 45 kPa absolute hence from equation 'i' we obtain
![P_{surface}=P(h)+\rho gh](https://tex.z-dn.net/?f=P_%7Bsurface%7D%3DP%28h%29%2B%5Crho%20gh)
Applying values we get
![P_{surface}=45\times 10^{3}+0.828\times 9.81\times 6400](https://tex.z-dn.net/?f=P_%7Bsurface%7D%3D45%5Ctimes%2010%5E%7B3%7D%2B0.828%5Ctimes%209.81%5Ctimes%206400)
![P_{surface}=96.98\times 10^{3}Pa=96.98kPa](https://tex.z-dn.net/?f=P_%7Bsurface%7D%3D96.98%5Ctimes%2010%5E%7B3%7DPa%3D96.98kPa)
Now the pressure in terms of head of mercury is given by
![h_{Hg}=\frac{P}{\rho _{Hg}\times g}](https://tex.z-dn.net/?f=h_%7BHg%7D%3D%5Cfrac%7BP%7D%7B%5Crho%20_%7BHg%7D%5Ctimes%20g%7D)
Applying values we get
![h=\frac{96.98\times 10^{3}}{13600\times 9.81}=0.727m=727mmHg](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B96.98%5Ctimes%2010%5E%7B3%7D%7D%7B13600%5Ctimes%209.81%7D%3D0.727m%3D727mmHg)
Answer:
The white lined paper
Explanation:
The teacher is most likely putting the while line paper in jeopardy because of the detail process involved in taking care of the paper prior to the submission of the home work.
The fact that a mistake must not be visible due to the instruction of every erasures being thorough and clean. this can cause jeopardy to the paper.
