Answer:
The answer to the question is
3340800 m far
Explanation:
To solve the question, we note that acceleration = 29 m/s²
Time of acceleration = 8 minutes
Then if the shuttle starts from rest, we have
S = u·t+0.5·a·t² where u = 0 m/s = initial velocity
S = distance traveled, m
a = acceleration of the motion, m/s²
t = time of travel
S = 0.5·a·t² = 0.5×29×(8×60)² = 3340800 m far
Atoms ere electrically neutral because they have equal number of protons and electrons. If an atom lose or gain one or more electrons it becomes an ion.
Answer:
468 m
Explanation:
So the building and the point where the laser hit the water surface make a right triangle. Let's call this triangle ABC where A is at the base of the building, B is at the top of the building, and C is where the laser hits the water surface. Similarly, the submarine, the projected submarine on the surface and the point where the laser hit the surface makes a another right triangle CDE. Let D be the submarine and E is the other point.
The length CE is length AE - length AC = 284 - 234 = 50 m
We can calculate the angle ECD:
![tan(\hat{ECD}) = \frac{ED}{EC} = \frac{100}{50} = 2](https://tex.z-dn.net/?f=tan%28%5Chat%7BECD%7D%29%20%3D%20%5Cfrac%7BED%7D%7BEC%7D%20%3D%20%5Cfrac%7B100%7D%7B50%7D%20%3D%202)
![\hat{ECD} = tan^{-1} 2 = 63.43^o](https://tex.z-dn.net/?f=%5Chat%7BECD%7D%20%3D%20tan%5E%7B-1%7D%202%20%3D%2063.43%5Eo)
This is also the angle ACB, so we can find the length AB:
![tan(\hat{ACB}) = \frac{AB}{AC} = \frac{AB}{234}](https://tex.z-dn.net/?f=tan%28%5Chat%7BACB%7D%29%20%3D%20%5Cfrac%7BAB%7D%7BAC%7D%20%3D%20%5Cfrac%7BAB%7D%7B234%7D)
![2 = \frac{AB}{234}](https://tex.z-dn.net/?f=2%20%3D%20%5Cfrac%7BAB%7D%7B234%7D)
![AB = 2*234 = 468 m](https://tex.z-dn.net/?f=AB%20%3D%202%2A234%20%3D%20468%20m)
So the height of the building is 468m
Answer:
Solid: metal alloy
Liquid: beer
Gas: Air
Explanation:
A solution is a type of mixture where the solvent and solute are homogeneously mixed. Homogeneous mixture means that the solute shouldn't be able to be seen with the naked eye, filtered and stable enough.
Metal alloy will be an example of a solution in solid-state. Beer is a solution made of liquid alcohol and liquid water. Air mostly composed of nitrogen, but it has oxygen, carbon dioxide, and many other substances in gaseous form.
