/sci/ - Science & Math

POSTED THIS IN /adv/ ALREADY, I'M IN REAL NEED OF SOMEONE WHO KNOWS, THOUGH.
I'm about to decide what I'm going to study for the future. My number one choice is Physical Engineering, seconds one I'm unable to translate it adequately "Ingeniería Civil" which doesn't exactly mean it has anything to do with civilians, you basically do shit about constructions and study floors and stuff.
I would be satisfied to get the most information posible on the first choice, Physical Engineering, things such as "Is it any good?"
"Does your university/institute have such a career? and if so, where from?" "To anyone who's is already graduate on Physical Engineering, was it hard for you to find a job? Are you poor as shit? Are you starving?"
Such a worry as to ask those questions comes from the fact that in my country it is not very popular and the local Autonomous University just launched it, it's generation #1.
So that doesn't quite inspire much confindence about it.
Anyway, I'd be glad to hear that there's a country in the world where these Engineers are appreciated and given decent jobs, anyone, anything?
Also why shouldn't I just kill myself?

I have to write this paper for physics class on "anything about physics on a topic" and I can't think of something really easy that has a lot of highschool-level physics involved such as amusement parks, but everyone's doing that and I'm sure there's something even easier. Any suggestions? I only need three pages but it doesn't even have to be comprehensive. Hope that makes sense. So, any easier topics than amusement parks that involve physics? Thanks in advance, sorry if this is an annoying question.

Sewage at a certain pumping station is raised vertically by 5.83 m at the rate of 1 910 000 liters each day. The sewage, of density 1 050 kg/m3, enters and leaves the pump at atmospheric pressure and through pipes of equal diameter.

Find the output mechanical power of the lift station.

Help, please. I have no idea what I'm doing

A Chinook salmon has a maximum underwater speed of 3.0 m/s, and can jump out of the water vertically with a speed of 6.9 m/s. A record salmon has a length of 1.5 m and a mass of 61 kg. When swimming upward at constant speed, and neglecting buoyancy, the fish experiences three forces: an upward force F exerted by the tail fin, the downward drag force of the water, and the downward force of gravity. As the fish leaves the surface of the water, however, it experiences a net upward force causing it to accelerate from 3.0 m/s to 6.9 m/s. Assuming that the drag force disappears as soon as the head of the fish breaks the surface and that F is exerted until 2/3 of the fish's length has left the water, determine the magnitude of F.

help on what to do, the answer is 1780N

A person looking out the window of a stationary train notices that raindrops are falling vertically down at a speed of 6.82 m/s relative to the ground. When the train moves at a constant velocity, the raindrops make an angle of 25° when they move past the window, as the drawing shows. How fast is the train moving?

Help plz?

Listen /sci/ i need your help. I am really tired and can't focus on my physics, All i ask is for help on some problems.
