The torque on the coil from the field is maximized. (a) What is the angle between and the coil's magnetic dipole moment? (b) What is the number of turns in the coil? (c) What is the magnitude of that maximum torque?

(a) What is the angle between and the coil's magnetic dipole moment.

The angle between and the coil's magnetic dipole moment is 90°, because it is perpendicular to the field since there is maximum torgue.

(b) What is the number of turns in the coil?

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

according to jean piaget, in what stage of cognitive development are children able to understand conservation task?

b. preoperational
