Answer to Problem 1Q

The law of conservation of energy is used when there is no non-conservative force on the system, the law of conservation of linear momentum is used when there is only internal force which does not affect the system and the law of conservation of angular momentum is used when there is no external torque on the system.

Explanation of Solution

The law of conservation of energy explains that energy never is created nor destroyed. It only changes from one form to other form of energy. The law of conservation of energy is used when there is no non-conservative force on the system. Non-conservative force is dispersing forces like friction or air resistance, which take away energy from the system.

The law of conservation of linear momentum explains that the momentum of the system is conserved when there is no external force is applied to the system. This law of conservation of linear momentum is applicable when there is only internal force which does not affect the system.

The law of conservation of angular momentum explains that the angular momentum of the system is conserved when the external torque is not applied to the system. This law of conservation of angular momentum is applicable when there is no external torque on the system.

Conclusion:

Therefore, the law of conservation of energy is used when there is no non-conservative force on the system, the law of conservation of linear momentum is used when there is only internal force which does not affect the system and the law of conservation of angular momentum is used when there is no external torque on the system.

When an electromagnetic wave is reflected at normal incidence on a perfectly conducting surface, the electric fieldvector of the reflected wave at the reflecting surface is the negative of that of the incident wave.a) Explain why this should be so.b) Show that the superposition of the incident and reflected waves results in a standing wave.c) What is the relationship between the magnetic field vector of the incident and reflected waves at the reflectingsurface?
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?
