The galactic disk is a component of the spiral galaxies and consists of stellar and gaseous components as it forms a random motion with the circular objects that orbit around the galactic center.

The rotational curve in a milky way is similar to that of the rotation of the universal rotating disk and is evident by the dark matter in the galaxies.

Which of the four cars had the least net force applied to it when it was launched down the ramp

castortr0y [4]

The least net force applied : Car 3(12 N)

<h3>Further explanation </h3>

Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object

∑F = m. a

Car 1 ⇒m=0.5 kg, a=36 m/s²

$\tt \sum F=0.5\times 36=18~N$

Car 2⇒m=0.8 kg, a=50 m/s²

$\tt \sum F=0.8\times 50=40~N$

Car 3⇒m=0.6, a=20 m/s²

$\tt \sum F=0.6\times 20=12~N$

Car 4⇒m=1, a=19~m/s²

$\tt \sum=1\times 19=19~N$
