Answer:
B. An electric current into a magnetic field
Explanation:
The generation of electrical power requires relative motion between a magnetic field and a conductor. In a generator, mechanical energy is converted into electrical energy. The electricity produced by most generators is in the form of alternating current.
11.3 Electromagnetic spectrum (ESADK)
EM radiation is classified into types according to the frequency of the wave: these types include, in order of increasing frequency, radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.
how does the electric force between two charged particles change if the distance between them is increased by a factor of 3?
a. it is reduced by a factor of 3
Answer:
Person B
Explanation:
Person B will hear the frequency that is lower than the B- flat.
Answer:
Explanation:
Given
See attachment for the graph
Required
Determine the frequency
Frequency (F) is calculated as:
Where
T = Time to complete a period
From the attachment, the wave complete a cycle or period in 3 seconds..
So:
--- Approximated
