The magnetometer will measure the total magnetic field. Which of the components should be zero when the dipole is oriented along the y-axis, based on what you learned in the previous lab about the direction of magnetic field lines due to a dipole magnet

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.

If you wanted to move an electron from the positive to the negative terminal of the battery, how much work w would you need to do on the electron? enter your answer numerically in joules.

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
