Answer:
Option D
Explanation:
As the question mentions losing its carbonation. Option D is the only option that mentions carbon dioxide gas leaving the solution.
Because during a phase change nothing really happens. Before a phase change, energy and temperature will increase or decrease as well as after.
Answer:
h= 45.87 m.
Explanation:
Data given:
Vf= 30m/s , and we know that g = 9.8 m/s²
The ball has an initial velocity of zero Vi = 0 m/s²
To Find:
Height of the building = ?
Solution:
According to 3rd law of the motion;
2aS= Vf² - Vi² ( S= h , a=g)
2*9.81*h = (30)² - (0)²
h= 45.87 m.
Answer:
Explanation:
<u>Given Data:</u>
Radius = r = 40 m
Speed = v = 25 m/s
<u>Required:</u>
Centripetal Acceleration = 
= ?
<u>Formula:</u>
<u>Solution:</u>
![\sf a_{c} = \frac{v^2}{r} \\\\a_{c} = \frac{(25)^2}{40} \\\\a_{c} = \frac{625}{40} \\\\a_{c} = 15.6 m/s^2\\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Csf%20a_%7Bc%7D%20%3D%20%5Cfrac%7Bv%5E2%7D%7Br%7D%20%5C%5C%5C%5Ca_%7Bc%7D%20%3D%20%5Cfrac%7B%2825%29%5E2%7D%7B40%7D%20%5C%5C%5C%5Ca_%7Bc%7D%20%3D%20%5Cfrac%7B625%7D%7B40%7D%20%5C%5C%5C%5Ca_%7Bc%7D%20%3D%2015.6%20m%2Fs%5E2%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)

Answer:
Hey, how you doing.
I think (warning I said think not to know!) that it is A because of the following:
Eruptions can be predicted if you have a good history of their activity. you also need to have lots of equipment constantly monitoring. Tsunamis can't really be predicted because earthquakes can't (that's why B is wrong). But however, if there is a giant asteroid impact you can predict that it will cuase i giant tsunamis.
A is the only one with 1 correct answer so I would go with it.
