Answer:
It is virtual and behind the mirror
Explanation:
When an image is produced by a mirror, we have the following situations:
- The image is said to be in front of the mirror if it is on the same side of the object, with respect to the mirror
- The image is said to be behind of the mirror if it is on the opposite side of the object, with respect to the mirror
Moreover:
- The image is said to be real if it is in front of the mirror
- The image is said to be virtual if it is behind the mirror
In this case, the image (located at point I) is on the opposite side of the object (located at point O), so it is virtual and behind the mirror.
The right answer for the question that is being asked and shown above is that: "B. condensation from the ocean and then evaporation into a cloud." a water molecule transfer from the ocean to form part of a cloud in the atmosphere is that <span>condensation from the ocean and then evaporation into a cloud</span>
Answer:
![F = 3.17 \times 10^4 N](https://tex.z-dn.net/?f=F%20%3D%203.17%20%5Ctimes%2010%5E4%20N)
Part b)
Force will act at the center of the window
Explanation:
Pressure at the centre of the window is given as
![P = P_o + \rho gH](https://tex.z-dn.net/?f=P%20%3D%20P_o%20%2B%20%5Crho%20gH)
here we know that
![P_o = 1.01 \times 10^5 Pascal](https://tex.z-dn.net/?f=P_o%20%3D%201.01%20%5Ctimes%2010%5E5%20Pascal)
![\rho = 1.028 \times 10^3 kg/m^3](https://tex.z-dn.net/?f=%5Crho%20%3D%201.028%20%5Ctimes%2010%5E3%20kg%2Fm%5E3)
g = 9.81 m/s/s
H = 6 m
![P = (1.01\times 10^5) + (1.028\times 10^3)(9.81)(6)](https://tex.z-dn.net/?f=P%20%3D%20%281.01%5Ctimes%2010%5E5%29%20%2B%20%281.028%5Ctimes%2010%5E3%29%289.81%29%286%29)
![P = 1.615\times 10^5 Pa](https://tex.z-dn.net/?f=P%20%3D%201.615%5Ctimes%2010%5E5%20Pa)
now the area of the window is given as
![A = \pi r^2](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%20r%5E2)
![A = \pi(0.25)^2 = 0.196 m^2](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%280.25%29%5E2%20%3D%200.196%20m%5E2)
Now force on the window is given as
![F = 0.196(1.615\times 10^5) = 3.17\times 10^4 N](https://tex.z-dn.net/?f=F%20%3D%200.196%281.615%5Ctimes%2010%5E5%29%20%3D%203.17%5Ctimes%2010%5E4%20N)
Part b)
Force will act at the center of the window
