The role of a resistor in an electrical circuit is to <u>hinder the movement of charge through a circuit</u>
Explanation:
A charge is carried through a wire by current (indicated as <em>I</em> in physics S.I connotation). Higher current means the rate at which the charge is flowing through the wire is fast. High resistance of the wire means the charge flows with difficulty hence slower. Resistance is given by the formulae;
R = V/I whereby;
R = resistance
V = voltage
I = current
As you can observe <em>R</em> (resistance) is inversely proportional to<em> I </em>(current). Meaning the higher the resistance the lower the current.
Answer: 2 hr 45 min
Explanation:
Given
The average speed between San Diego and Los Angeles is
time taken for this trip is
Distance between San Diego and Los Angeles is
For Friday afternoon, the average speed is
time taken to complete the trip is
Sound waves require a medium to travel through. :D
The most important thing you should remember in order to get how is its linear momentum relative to the surface is that the<span> point on the circumference is moving at w rad/second.
Therefore, here is the solving formulae:
if </span>
you can easily get <span> linear momentum p :
</span>
I'm sure that helps.
