Answer:
B) is perpendicular to the magnetic field
You measure the total distance the bike travels, and the total time it takes to travel that distance. You then divide the distance by the time
Answer:
a)
b)
Explanation:
The current flowing in a R-L series circuit is given by
Where τ is the time constant and is given by
Where L is the inductance and R is the resistance
Assuming the current has reached steady state when it is at 99% of its maximum value,
Therefore, it would take t = 4.6τ to reach the steady state.
(b) If an emergency power circuit needs to reach steady state within 1.2 ms of turning on and the circuit has a total resistance of 72 Ω, what values of the total inductance of the circuit are needed to satisfy the requirement?
Therefore, an inductance of 0.0187 H is needed to satisfy the requirement.
