Lol please give me points
Answer:
1. The magnetic flux line form a closed loop.
2. The magnetic flux line repel each other.
3. The magnetic flux line never intersect.
Answer:
8.62m/s²
Explanation:
the particle is experiencing both translational and circular motion
v=4t²
=
=8t
at t=1s,
=8(1)=8m/s²
= 
at t=1, v= 4(1)² = 4m/s
=4²/5
=3.2m/s²
∴ magnitude of total acceleration, a
a=
a=
a=
a=
a=8.62m/s²
