Answer:
A. "The electric force vector is along the direction of the electric field, whereas the magnetic force vector is perpendicular to the magnetic field."
D. "The kinetic energy of a charged particle moving in an electric field is not altered, whereas the kinetic energy of a charged particle moving in a magnetic field is either increased or decreased, depending on the direction of motion."
Explanation:
Electric fields originate from voltage differences, the higher the voltage, the stronger the resulting field. Magnetic fields originate from electric currents, a stronger current results in a stronger field. An electric field exists even if there is no current. When there is current, the magnitude of the magnetic field will change with power consumption, but the strength of the electric field will remain the same.
Float. This is because water has a density of 1 g/ml, so anything less than this will float.
The sound wave is 1.0 meters
Methane is emitted during the production and transport of coal,natural gas,and oil,while fluorinated gases are emitted from a variety industrial processes.
The initial angular velocity of the motor is zero, while the final angular velocity is 1800 rev/min. Let's convert this into rad/s, keeping in mind that
we have
And so now we can calculate the angular acceleration of the motor:
