Why is the equation for the inductance of an ideal long coil and a toroid identical if the coil length and mean path lengths are equal (assume equal A, N, and μ)? (Hint: consider the assumptions underlying the inductance expressions. g

During the apollo moon missions, astronauts were concerned about the effects of newton's third law of motion when: o a. they ejected waste water, because they were concerned that it would push them off course. o b. they reentered earth's atmosphere, because they were carrying heavy moon rocks. o c. they took off from earth, because a large force was required to generate large acceleration. o d. they detected incoming space debris, because the inertia of the debris could damage their ship.
