Answer:Both
Explanation:
There are three ways to increase the induced voltage in electromagnetic induction:
1) increase the speed at which the conductor moves through the magnetic field. This means that the lines of flux are cut more quickly and more emf is induced.
2) use stronger magnets which provides a stronger magnetic field and more densely packed lines of flux.
3) use a coil of multiple loops.
Hence both technicians were correct.
The sun is at the solstices on roughly June 21 and December 21.
June 21 is the "Summer" solstice in the Northern hemisphere.
At that time, the sun is directly overhead at a point on the Tropic
of Cancer, about 23.5° North of the equator.
December 21 is the "Summer" solstice in the Southern hemisphere.
At that time, the sun is directly overhead at a point on the Tropic
of Capricorn, about 23.5° South of the equator.
<u>Answer:</u>
Things become hot and cold because of the transfer of energy.
<u>Explanation:</u>
The energy possessed by an object or system is called thermal energy and heat is the flow of this energy. While the law of conversation of energy states that energy is not destroyed or created, it just transfers from one object to another.
When a hot object is placed in normal conditions, it transfers heat to the environment until both are at the same temperature and heat transfers from the environment to the cold objects placed in normal conditions.
