Let the left end A and the right end B. 
Let w = the weight of the full beam. 
0 = -(w/2)*(L/4) - (w)*(L/2) + Fa*L 
Fa = [(w/2)*(L/4) + (w)*(L/2)]/L = w/8 + w/2 = 5/8*w = 5/8*m*g = 5/8*1800*9.81 Fa = 11036.25 N 
Fa + Fb = w Fb = w - Fa = 1.8*(1800*9.81) - 11036.25 Fb = 20748.15 N

An aurora occurs when ____
ASHA 777 [7]

The short answer to how the aurora happens is that energetic electrically charged particles (mostly electrons) accelerate along the magnetic field lines into the upper atmosphere, where they collide with gas atoms, causing the atoms to give off light.

An airplane has a starting velocity of 300m/s. It then accelerates at a rate of 45m/s2 for a time of 10s. What is it's final vel
Olenka [21]
A = (v - u) / t

a = acceleration
v = final velocity
u = initial velocity
t = time

45 = (v - 300) / 10

45 × 10 = v - 300

450 + 300 = v

v = 750 m/s

Hope this helps!

P.S. Let me know if you need an explanation
