Answer: Option (1) is the correct answer.
Explanation:
The vertical distance between crest or trough from the origin or equilibrium point is known as amplitude of a wave.
In the given pictures, a wave that shows maximum height from the origin will have the maximum amplitude. Whereas the wave that shows minimum height from the origin will have the smallest amplitude.
Thus, we can conclude that waves shown in option 1 will have the smallest amplitude.
Answer:6.298,4.1,1.9015
Explanation:
Wavelength=
==4.397 m
Distance of 3rd speaker from speaker A is x
From B 78-x
Difference between the distances must be a whole number of wavelengths
First
for 1 st wavelength
2x=8.2+4.397=12.597
x=6.298m
second
For zero wavelength
2x=8.2
x=4.1m
Third
x=1.9015 m
An RC circuit is an electrical circuit composed of resistors and capacitors, where the charging time of the circuit is proportional to the magnitude of the electrical resistance
and the capacity
of the capacitor.
As shown below:
In this context, the electrical resistance is the opposition to the flow of electrons when moving through a conductor.
Therefore:
<h2>When a capacitor is being charged in an RC circuit, the current flowing through a resistor <u>decreases</u>.</h2>
And the correct option is b.
