How can you show that unlike poles attract each other while like poles repel each other? magnetic attraction and repulsion Bar magnets showing the attraction of opposite poles and repulsion of like poles. if you bring the South pole of the magnet B near the north pole of the suspended magnet A as shown in […]
What are advantages of using microwaves?
What are advantages of using microwaves? Advantages of Microwaves Supports larger bandwidth and hence more information is transmitted. More antenna gain is possible. Higher data rates are transmitted as the bandwidth is more. Antenna size gets reduced, as the frequencies are higher. Low power consumption as the signals are of higher frequencies. What are the […]

What is true for electromagnetic waves?
What is true for electromagnetic waves? Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields. They are also perpendicular to the direction of the EM wave. How […]
What are the benefits of taking the MIQ?
What are the benefits of taking the MIQ? The MIQ permits the comparison of the vocational needs of individuals with estimates of reinforcers present in 185 occupations representative of the major fields and levels of the world of work. The correspondence of occupational reinforcers to an individual’s needs permits the prediction of job satisfaction. What […]
Does amplitude equal loudness?
Does amplitude equal loudness? The amplitude of a sound wave determines its loudness or volume. A larger amplitude means a louder sound, and a smaller amplitude means a softer sound. The volume we receive thus depends on both the amplitude of a sound wave and whether its frequency lies in a region where the ear […]

Why are outlets never wired in series?
Why are outlets never wired in series? But, in fact, all household receptacles are always wired in parallel, and never in series. In a series circuit, current must pass through a load at each device. And if the appliance in the first receptacle shorted out or failed in some other way, it would interrupt the […]
