Answer:
P = d g h pressure due to density of liquid of height h
d1 g h1 = d2 g h2 since P1 equals P2
d1 h1 = d2 h2 and the density of Hg is 13.6 times that of water
h2 = (d1 / d2) * h1 = 13.6 * 70 cm = 952 cm or 9.52 m
The use Major changes in mineral deposits in the rock layers.
Answer:
The angular speed is ![w = 5.89 \ rad/s](https://tex.z-dn.net/?f=w%20%3D%205.89%20%5C%20rad%2Fs)
Explanation:
From the question we are told that
The time taken is ![t = 1.6 s](https://tex.z-dn.net/?f=t%20%3D%201.6%20s)
The number of somersaults is n = 1.5
The total angular displacement during the somersault is mathematically represented as
![\theta = n * 2 * \pi](https://tex.z-dn.net/?f=%5Ctheta%20%20%3D%20%20n%20%2A%20%202%20%2A%20%20%5Cpi)
substituting values
![\theta = 1.5 * 2 * 3.142](https://tex.z-dn.net/?f=%5Ctheta%20%20%3D%20%201.5%20%2A%20%202%20%2A%20%203.142)
![\theta = 9.426 \ rad](https://tex.z-dn.net/?f=%5Ctheta%20%20%3D%209.426%20%5C%20rad)
The angular speed is mathematically represented as
![w = \frac{\theta }{t}](https://tex.z-dn.net/?f=w%20%3D%20%20%5Cfrac%7B%5Ctheta%20%7D%7Bt%7D)
substituting values
![w = \frac{9.426}{1.6}](https://tex.z-dn.net/?f=w%20%3D%20%20%5Cfrac%7B9.426%7D%7B1.6%7D)
![w = 5.89 \ rad/s](https://tex.z-dn.net/?f=w%20%3D%205.89%20%5C%20rad%2Fs)
Answer:
very smooth and polished glass mirror
Explanation:
The best type of mirror for this would be a very smooth and polished glass mirror. A metal mirror will also work but it would need to be extremely polished. This would allow light to efficiently be reflected across the room, thus effectively adding an "extra" light source to the room. If the mirror is not smooth then the light may become distorted and not reflect properly as it is supposed to. This may defeat the entire purpose of the mirror for this scenario.
