Answer:
- F1.x ≈ -28.93
- F1.y ≈ 34.47
- F2.x = 70
- F2.y = 0
- (F1+F2).x ≈ 41.07
- (F1+F2).y ≈ 34.47
- |F1+F2| ≈ 53.62
- ∠(F1+F2) ≈ 40.0°
Explanation:
A suitable calculator can show you the vector components and their resultant in polar or rectangular format. (See attached.) 2D vectors are conveniently treated as complex numbers, which is why the y-component values are shown as imaginary.
(The 50° angle measured from the -x axis is equivalent to 130° measured from the +x axis, which is the reference we're using here.)
If you'd like to compute the vector components by hand, they are ...
(x, y) = magnitude×(cos(angle), sin(angle))
This notation is sometimes abbreviated <em>magnitude cis angle</em>, a reference to the complex number form x+yi.
Answer: Starting of with Chemical Engineering something that they may encounter is a lack of adeptness man puissance. People that are working there are not much adept or having cognizance regarding to chemical industry. Something someone with a Civil engineering might encounter is the quandary of sustainable construction, and amendment construction site safety. To go on , something that Electrical engineering might encounter is a Non technical , Virtually an electrical engineer has to deal with an astronomical range of machines , control panels,instruments. For example you are working with circuit breakers,as anon as you’ll have expertise on any particular type of circuit breaker, there's a transmutation in trend and the CB you are working with is already obsolete. And last but no least , Something someone might encounter while doing Mechanical engineering is there toxic substances because their work environment is susceptible to fires, explosions, structural failures and equipment malfunctions.

NASA scientists have determined that the chance a single person would get hit by a piece of falling satellite is one in 3,200. What can you infer based on this probability?
A. Satellites that enter Earth’s atmosphere land mostly in the ocean.
B. NASA does a good job informing people of when satellites will enter the atmosphere.
C. Satellites that enter Earth’s atmosphere land mostly in unpopulated areas.
D. Much of a satellite is destroyed during the process of entering Earth’s atmosphere.
