Answer:
When the electrical current passes through the conductors, the polarity is changed, and the diaphragm interacts with the permanent magnets, vibrating and creating sound.
Explanation:
Hi there!
a)
We can find the angular velocity at t = 2.0 s by plugging in this value into the equation.
b)
The angular acceleration is the derivative of the angular velocity, so:
Thus, the angular acceleration is a <u>constant 25 rad/s².</u>
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.
When a battery is connected to a circuit, the electrons from the anode travel through the circuit toward the cathode in a direct circuit. The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current.
