T = ?
v1 = 0mph
v2 = 60mph
a = 8.7mph/s
Therefore, it takes 6.90 seconds for Jill to accelerate from 0 to 60 miles per hour.
Answer:Magnetic fields are invisible, at least usually. But scientists from NASA's Space Sciences Laboratory have made them visible as "animated photographs," using sound-controlled CGI and 3D compositing.
Explanation:
The answer is B.)
This is because for years scientists have build up and found discoveries that led to recent discoveries brought by previous scientists.

The eastward movement of winds and currents in the pacific
Answer:
t = 2 v₀ / g
Explanation:
For this projectile launch exercise we use the displacement equations
x = vox t
y = y₀ + 
t - ½ g t²
As it is launched horizontally the vertical velocity is zero and the point of origin of the coordinate system is here, so y₀ is zero.
x = v₀ t
y = ½ g t²
They ask us for the time for which
x = y
vo t = ½ g t²
t = 2 v₀ / g
