Answer:
Electric current produces a magnetic field. This magnetic field can be visualized as a pattern of circular field lines surrounding a wire. ... Magnetic Field Generated by Current: (a) Compasses placed near a long straight current-carrying wire indicate that field lines form circular loops centered on the wire.
Explanation:
The Earth's gravitational pull and the table's force are of equal magnitude and in opposite directions, they balance each other.
<u>Explanation:</u>
A book placed on a surface have two forces acting on it which are, a force that pulls it toward the ground in a downward direction, that is gravitational pull and a second which is acted on the book on upward direction making a balance on the object.
This follows Newton’s third law of motion that states every action has an equal and opposite reaction.
Answer:
C. A glass of lemonade starting to freeze in a warm room.
Explanation:
This is because there is no source of cold to properly freeze the lemonade, freezing happens when a cold source starts to slow down the movement of atoms. So if there's nothing there to freeze it, it can't freeze.
Alternatively, there are some materials that harden when not subjected to heat, but that's not freezing. It's just cooling.
Answer:
cool its surroundings
