Answer:
A magnet is demagnetized. There is a decrease in chemical potential energy. There is an increase in thermal energy. And there is an increase in energy in the form of demagnetization.
Electromagnetic waves travel through a vacuum, Because it has an electric and a magnetic component in it.
<u>Explanation:</u>
The vibration that is created in an electric charge is the cause for the creation of an electromagnetic wave. The electromagnetic waves contains a magnetic and an electric component in it because of this vibration. The transportation of the energy at 3.00 x 108 m/s speed in an empty space.
The electric and magnetic components that are present in an electromagnetic wave is called fields. There is a vibration at an angle of 90 degree by these fields with respect to the wave motion. The light speed remains unchanged.
Answer:
13 atoms
Explanation:
Look at the subscripts.
“Mg₃” means that there are 3 magnesium atoms; “PO₄” means that there is 1 phosphorus atom and 4 oxygen atoms. But note that the PO₄ group has a subscript too: 2. This multiplies the atom count by 2, so you have 2 phosphorus atoms and 8 oxygen atoms.
3 + 2 + 8 = 13
