25 volts
Explanation:
Use Ohm's law to find the potential drop:
V = IR
= (0.5 A)(50 ohms)
= 25 volts
<h2>
Answer:</h2>
If you triple the charge, the electric potential is 3V.
<h2>
Explanation:</h2>
If you triple the charge, the electric potential is 3V. Put another way, the value of the electric potential at the same location is tripled if the strength of the charge is tripled.
<em>But why this is true?</em>
Well, the potential V due to a single point charge q is:
If the strength of the charge is tripled means that our new q1=3q, therefore:
So you can see that in fact if you triple the charge, the electric potential is 3V.
The line spectrum is also known as the emission light spectrum.
The ELS shows what colors of light are released when an element(or a specific compoud) is burned or electricity is sent through the gaseous form.
The ELS can be used to identify elements because each element has a different ELS. Elements like Tungsten produce a white light when burned, so their ELS has many line close together. This is why tungsten was used for lightbulbs.
Since
<span>Vf^2 = 2*a*S </span>
<span>Given S=3.6m, thus </span>
<span>a = Vf^2/(2*3.6) </span>
<span>a = Vf^2/7.2 </span>
<span>Let d be the distance along the slope at which the velocity is 0.5Vf, then </span>
<span>(0.5Vf)^2 = 2*a*d </span>
<span>or </span>
<span>d = (0.5*Vf)^2/(2*a) </span>
<span>with a = Vf^2/7.2, we have </span>
<span>d = 0.9 m</span>
