The generation of a magnetic field by an electric current is _electromagnetism_.
Answer:
It takes millions sometimes hundreds of millions Explanation:
Explanation:
No surface is perfectly smooth. Everything has irregularities, like bumps and ridges. Static friction is the friction between non-moving objects when their surfaces lock together. When an object is sliding, its surface skips and jumps along the surface of the other object. Because there's less locking between the surfaces, the sliding friction is less than the static friction.
Answer: The high tide on the opposite side of the Earth than the moon is on is because of the Moon's pull of gravity on the water.
Explanation: The reason for this is because the moon has its own pull of gravity on us. So when the moon is, say, highest over Asia, the tides over there will be lower. And when the moon is highest over Asia, the tides around the Americas will be higher.
