Answer:
Amplitude.
Explanation:
A wave can be defined as a disturbance in a medium that progressively transports energy from a source location to another location without the transportation of matter.
In Science, there are two (2) types of wave and these include;
I. Electromagnetic waves: it doesn't require a medium for its propagation and as such can travel through an empty space or vacuum. An example of an electromagnetic wave is light.
II. Mechanical waves: it requires a medium for its propagation and as such can't travel through an empty space or vacuum. An example of a mechanical wave is sound.
An amplitude can be defined as a waveform that's measured from the center line (its origin or equilibrium position) to the bottom of a trough or top of a crest.
Hence, an amplitude is a word that describes the maximum displacement a point moves from its rest position when a wave passes.
On a graph, the vertical axis (y-axis) is the amplitude of a waveform and this simply means that, it's measured vertically.
Mathematically, the amplitude of a wave is given by the formula;
x = Asin(ωt + ϕ)
Where;
x is displacement of the wave measured in meters.
A is the amplitude.
ω is the angular frequency measured in rad/s.
t is the time period measured in seconds.
ϕ is the phase angle.
<h3><u>Answer;</u></h3>
<u> = 55.2 Coulombs </u>
<h3><u>Explanation</u>;</h3>
We can determine Charge using the formula
Q =It, where Q is the amount of charge in Coulombs, I is the current in amperes and t is the time in seconds.
I = 0.92 amperes, t = 1 minute or 60 seconds
Charge = 0.92 × 60
<u> = 55.2 Coulombs </u>
Answer:
"Why"
Explanation: A scientific law is a description of how the natural world behaves under certain circumstances.
The closed path of an electric current is called the CIRCUIT.
