Explanation:
P = F/A
P = mg/A [ since F = mg ]
P = Vdg/A [ since m = Vd ]
P = Ahdg/A [ since V = Ah ]
P = hdg
Answer:
d = 771.3m
Explanation:
Let's first calculate the time of flight:
where Voy=0. Solving for t:
Now we calculate the horizontal displacement, wihch is the distance from the target to drop the package:
Xf = d = Vox*t
d = 180*4.285 = 771.3m
Density = mass/ volume (so here this is how you would solve the problem)
<span>D = 38.6 g/ 2 cm3 (first step)</span>
<span>D= 19.3 g/cm3 ( Do math and then you would get this)</span>

Modelling the structure of the atom is important because modeling replaces the real system with something similar but easier to examine. Option B
<h3>What is modeling?</h3>
A model is a representation of reality. We know that a model could help us to recreate reality in a manner that we could be able to relate fully with it. A model could be used also a means of explanation.
The atomic models that we have usually help us to understand more abut the atom. Therefore, modelling the structure of the atom is important because modeling replaces the real system with something similar but easier to examine. Option B
