Answer:
frequency of a wave can be measured by the number of crests in a second or more
Answer:
Magnetic field lines exit out of the North pole . Magnetic field lines enter into the South pole. Magnetic field lines travel around a bar magnet in closed loops.
Explanation:
Magnetic field lines shows the direction of a magnetic force and how it acts, it gives the direction of the magnetic field at that point in time.
For a bar magnetic, the magnetic field lines runs from the north pole to the south pole, i.e. it exits the north pole and enters into the south pole. This magnetic field lines also go through the magnet forming closed loops without ends.
Answer:
The answer is C either the frequency or the wave lenght of the light
Explanation:
The frequency determins the brightnes of a color and the wave lenght determines the spectrum
Satellites would be able to detect fires when they start and allow human monitors to review the information and issue warnings.
