You must find the component of the force before calculating
We know that
tan(∅) = y/x; where y will be the height of the balloon and x will be the distance from the milestone marker.
The marker that is further away will produce a smaller angle of depression.
tan(18) = height / x
x = height / tan(18)
The second marker is x + 1 miles away:
tan(16) = height / x + 1; substituting x:
tan(16) = height / (height/tan(18) + 1)
tan(16) x [(height / tan(18) + 1] = height
0.88h + 0.29 = h
h = 2.42 miles
Answer:
19 elements
Explanation:
1 carbon + 12 hydrogen + 6 oxygen = 19
I’m trying to get things expanded graph explanation sorry
Answer:
density = 5000 [kg/m^3]
Explanation:
Density is defined as the relationship between mass and volume.
Now we have:
m = 100 [gr] = 0.1[kg]
V = volume = 20[cm^3]
![20[cm^{3}]*1[\frac{m^{3} }{100^{3} cm^{3} } ] = 2*10^{-5}[m^{3} ]](https://tex.z-dn.net/?f=20%5Bcm%5E%7B3%7D%5D%2A1%5B%5Cfrac%7Bm%5E%7B3%7D%20%7D%7B100%5E%7B3%7D%20cm%5E%7B3%7D%20%7D%20%5D%20%3D%202%2A10%5E%7B-5%7D%5Bm%5E%7B3%7D%20%5D)
density = 0.1 / (2 x 10^-5)
density = 5000 [kg/m^3]
