Each cell has a size and shape that is suited to its job.
Answer:
It is an unbalanced force as the airplane has different newtons going into it on all sides. The airplane will probably move forward as 200 newtons push into its back. It will also possibly move up as 175 newtons push it up.
Answer:
This explanation from Physics/Geometry
60o |
|
| Fy (the vert. comp.)
↑
← 30o |
Fx (the horizontal componenet)
F = √(Fx2 + Fy2)
Fy = 50 · cos 60o = 50 · (1/2) = 25 N
Fx = 50 · cos 30o = 50 · (√3)/2 = 25√3 N
I see, that vector sign did not appear in my comment above, so the vector equation is
→ → →
F = 50 cos 30o i + 50 cos 60o j
Explanation:
To put it another way, stationary states are the same as time-independent currents. Moreover, such currents are not sources of radiation, according to Maxwell's theory. The atom will remain in its natural state and will not collapse due to a shortage of energy.
