An electromagnet is a made coil associated with a ferromagnetic core. ... When an electric current flows through the wire the solenoid generates a magnetic field similar to that of a bar magnet. An electromagnet is a solenoid wound around a central iron core.
Electromagnetism is a process through which a material is magnetized (temporarily or permanently) by Electric current. ... This is Electromagnetism.
Explanation:
By measuring the voltage drop before and after the resistors, and the current in the circuit, you can graph voltage vs current to get a line whose slope is equal to the equivalent resistance.
V = Req × I
For example, if you had two resistors in series, and each resistor was 1.5 Ω, then the equivalent resistance would be 3.0 Ω, and you would get the same graph as if there were a single 3.0 Ω resistor.
Answer:
option (a)
Explanation:
Maintaining distance while driving in traffic can avoid the chances of an accident.
When the driver is behind you is trying to pass you to avoid the collision you should maintain a distance greater than 3 sec.
Hence, option (a) is correct.
Microscope use to observe microscopic organisms such as bacteria, viruses, and others. The spontaneous observation that microorganisms move and transport through the air which serves as their medium or channel to transfer from one place to another. This microbiology or study with the use of the microscope greatly affects and contributed to the foul air theory on which traces of the sources of disease became the focus of their study. Diseases and properties of microorganisms, as well as, the solution on how to cure and fight these becomes possible with the availability of microscope.
