History suggests that the magnetic field of the Earth was in a reversed states during stone age. And it might happen in future. The domains realign as the Earth is continuously in motion.

An object falls from a high building and hits the ground in 8.0 seconds. Ignoring air resistance, what is the distance that it f
d1i1m1o1n [39]

Answer:

310 meters

Explanation:

Given:

v₀ = 0 m/s

t = 8.0 s

a = -9.8 m/s²

Find: Δy

Δy = v₀ t + ½ at²

Δy = (0 m/s) (8.0 s) + ½ (-9.8 m/s²) (8.0 s)²

Δy = -313.6

Rounded to two significant figures, the object fell 310 meters.

Why is it difficult to convert miles to yards
shepuryov [24]

There's really no "why", because it's not difficult at all.
 
Simply multiply the number of miles by 1,760, and bada boom,
there you have the same distance described in yards.
