Answer:
the primary coil current produces a magnetic field, which changes as the current changes. the iron core increases the strength of the magnetic field. the changing magnetic field induces a changing potential difference (voltage) in the secondary coil.
<span> Mass is a quantified value of how much matter is in you, while weight takes into account the effect of gravity. People will "weigh" less on the moon because of the lesser gravity, but they still have the same mass.</span>
Answer:
In space we feel weightlessness because the earth's gravity has less effect on us. The Earth's gravitational attraction at those altitudes is only about 11% less than it is at the Earth's surface. If you had a ladder that could reach as high as the shuttle's orbit, your weight would be 11% less at the top.

Hope this helps:)
Answer:
Wave A has a greater intensity and transfers more energy. Wave B has a greater intensity and transfers more energy.
Explanation:
In a stronger gravitational field a given mass will have a larger weight.
