If a dipole, starting from rest and initially pointing opposite to an external magnetic field, is slightly perturbed, it will rotate in order to point in the same direction of the external magnetic field (its lowest potential energy state), with its potential energy changing to kinetic energy (just like a ball given a slight push at the top of a hill rolling into a valley). considering this energy conversion, what is the angular speed of the dipole moment as it passes through its lowest potential energy state (when it points in the same direction as the external magnetic field)? group of answer choices

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?

1. when conducting a test on what kind of music increases the growth of plants, all of the following would fail to meet to fair test standard except (1 point) using different kinds of plants. giving some plants more water than others. exposing the plants to different types of music. using nutrient-rich soil for one and lesser soil for others. 2. engineering uses scientific thinking to solve real-world problems. (1 point) true false 3. what does it mean to test a hypothesis? (1 point) pass a quiz on other scientists’ results analyze only the results from scientific sources not make assumptions about how an experiment will turn out see if the results of an experiment are what the scientist predicted
