<span>In order to
change power, current or voltage should also be changed. Voltage is an
electromotive force, and also the quantitative expression that shows the
potential difference of the two points charged in an electrical field. So, before power will take place, it would
always be best to change also the voltage.</span>
Answer:
where the y axis is
Explanation:
In more simple terms, a horizontal line on any chart is where the y-axis values are equal. If it has been drawn to show a series of highs in the data, a data point moving above the horizontal line would indicate a rise in the y-axis value over recent values in the data sample.
Answer:
I think so
Explanation:
When the object is moving towards you the sound gets louder but when it's moving away it sounds farther away.
The equation you need to know in order to solve this problem is v=v0+at, where v is final velocity, v0 is initial velocity, a is acceleration, and t is time. Plug in and solve:
30=0+a(8)
30=8a
<em>*Divide both sides by 8*</em>
a=3/75m/s^2
Hope this helps!!
Answer:
The thickness of the film, t = 470.59 nm
Explanation:

For constructive interference, the net phase change, 
Then the thickness, 
m₁ = 1,2,3........
..............(i)
For destructive interference, the net phase change is 
m₂ = 1,2,3........
thickness,
..............(ii)
Equating (i) and (ii)


.............(iii)
From (iii), When m₁ =2, m₂ = 2
The thickness ,
then becomes

t = 470.59 nm
