Answer:
A group of atoms where the magnetic fields of the atoms point in the same direction is a magnetic domain.
Explanation:
- In every magnet's magnetic field there is a region where the magnetization is in the same direction. This region is known as magnetic domain.
- In the magnetic domain the atoms always points in the same magnetic filed direction.
- All the atom's magnetic field align in one particular direction.
- This region where atoms align is called as domains.
Answer:
-39.2m/s
Explanation:
Using the equation of motion;
v = u + at
Since the ball is thrown upward, the acceleration due to gravity acting on it will be negative, hence a = -g
v = u - gt
Since g = 9.8m/s²
t = 4.0s
u = 0m/s
v = 0 + (-9.8)(4)
v = 0 + (-9.8)(4)
v = -39.2m/s
Hence the speed of the ball before release is -39.2m/s
