Explanation:
the answer is y=strong winds move sand dunes in the desert
The friction is 2.5N. The Net force is 10 N - 2.5 N .= 7.5 N.
acceleration = 7.5 / 5 = 1.5 m/s^2
Gravity ALWAYS does that, and electrostatic force does it when two objects have opposite charges.
He studied galaxies, source: “Hubble proved that many objects previously thought to be clouds of dust and gas and classified as "nebulae" were actually galaxies beyond the Milky”
