Answer to Problem 1QAP

The statement is false because energy cannot travel faster than 3×108m/s .

Explanation of Solution

Energy is quantitative property that cannot be created or destroyed; it can only be transferred from one form to another. Various forms of energy are potential, kinetic energy, electric energy, etc. It can travel at very high speed; sound can travel with a speed of 343m/s.

Speed of light is the fastest speed in the universe. Light can travel in any medium or vacuum; it travels at a speed of 3×108m/s in vacuum. Vacuum is a region that contains no matter in it; it means light travels fastest in the vacuum; it slows down when enter into the medium.

Therefore, nothing can travel faster than light in vacuum.

Conclusion:

Thus, the statement is false because energy cannot travel faster than 3×108m/s .

Suppose there are two transformers between your house and the high-voltage transmission line that distributes the power. In addition, assume your house is the only one using electric power. At a substation the primary of a step-down transformer (turns ratio = 1:23) receives the voltage from the high-voltage transmission line. Because of your usage, a current of 51.1 mA exists in the primary of the transformer. The secondary is connected to the primary of another step- down transformer (turns ratio = 1:36) somewhere near your house, perhaps up on a telephone pole. The secondary of this transformer delivers a 240-V emf to your house. How much power is your house using? Remember that the current and voltage given in this problem are rms values.
In some places, insect "zappers," with their blue lights, are a familiar sight on a summer's night. These devices use a high voltage to electrocute insects. One such device uses an ac voltage of 3970 V, which is obtained from a standard 120-V outlet by means of a transformer. If the primary coil has 27 turns, how many turns are in the secondary coil? hel lp?
Hi,  Does Quantum physics theory means all branches for example quantum relativity, Quantum mechanics, Quantum field theory, and string theory? Can you explain each one of them? Best
