Scientists believe that on large scales the Universe is isotropic (the same in all directions). Thus, from our perspective, half of all spiral galaxies should spin clockwise, and half counter-clockwise.

Explanation:
Depends on the weight of the bird.
1) Half a mile is about 800m.
2) 14000 lbs = about 6 tones, same like couple 4WD
3) Fuel consumption is about 20L per 100km or 0.2l each 1km or 0.16L within 800m
4) density of fuel is about 70% of density of water so .... weight of 1.6L of fuel burned would be about 1.6*0.7=1.1 kg
So if birds mass would be below 1 kg - the bridge will not collapse. But if it would be a pelican with the mass of 9kg - it would be a drama :)
It protects us by keeping ultraviolet out and make sure everything lives
Distance=30 meters
displacement=10 meters
distance is the overall amount he travelled so 20+10=30 he travelled 30 meters
displacement is how far he is from where he originally started so if he ran 20 meters away but then 10 back he’s only 10 meters away from where he started 20-10=10
pretty sure this is right hope i helped
