Answer:
Explanation:
According to the law of conservation of energy, the total energy of the system can be expresed as the sum of the potential energy and kinetic energy:
When the spring is in its equilibrium position, that is , the object speed its maximum. So, we have:
In order to double its maximum speed, that is . We have:
Answer:
magnetic flux linkage includes number of turns, N while magnetic flux has no N
Since number of turns are not significant to units, they become similar.
I might have did mistake with calculations but this is how you should do.
Answer:
Thermopile is an electronic device that converts thermal energy into electrical energy.
A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.
