Answer:
Explanation:
The two triangles are similar what is the length of DE
Answer:
B = 9.16 10⁻² T
Explanation:
The speed selector is a configuration where the electric and magnetic force has the opposite direction, which for a specific speed cancel
q v B = q E
v = E / B
B = E / v
Let's calculate
B = 4.4 10⁵ / 4.8 10⁶
B = 9.16 10⁻² T
C: the mechanical energy isn't conserved. Some energy was lost to friction.
