They both exert an equal amount of force onto each other
They are experiencing the pull of leaving the atmosphere
A birds feather. Because a birds feather is way lighter than a model rocket, so it wild go down slower, in a waiver motion.
Answer: When electricity flows through it.
Explanation:
The electromagnet exhibits magnetic properties only as soon as current flows through the nucleus. Namely, the electric current in the space around the electrical conductor through which it passes creates a magnetic field. Unlike a permanent magnet, which has a permanent property of magnetism, the electromagnet is a temporary magnet because the magnetic field also disappears when the current ceases.
Using v = u + at
u = 0m/s
t = 8 sec
a = 10m/s^2
therefore, final velocity, v = 0+ 8*10
v= 80m/s
