Answer:
we know that current = charge/time
Explanation:
therefore,
A = 8000/120
A => 66.666.... amperes
Answer:
I wish I knew the answer to that question
Answer:
The water releases energy which causes the water molecules to have less kinetic and potential energy, changing their configuration from liquid to solid.
Explanation:
The conversion of water to ice is a phase change from liquid to solid. There is no chemical action taking place in this process just the state of matter taking up a new form.
- This phase change is called freezing.
- In freezing, the liquid water loses energy to the surroundings.
- By so doing, the water molecules have lesser energy
- The then take up fixed position within the lattice.
- This changes the state to solid with a well - ordered arrangement.
NATURAL MAGNETS
A natural magnet is one that occurs naturally in nature. All natural magnet are permanent magnets , meaning they never lose their magnetic power.
Natural magnet can be found in Sandy deposits in various part of the earth .
The strongest natural magnetic material is LODESTONE also called magnetite.
ARTIFICIAL MAGNETS
These are magnets made by people.
It's these magnets that is in our refrigerator doors, which have extra-stronge magnetic power. There are two types of of artificial magnets. Temporary and Permanent Magnets.
Examples of artificial magnets are; electromagnet and the paper clip.
Examples of Permanent Magnets are; Alnico
