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:
A. Known variables include
Wavelength = 600nm
Theta= 65°
m= 2
B.
d= m x wavelength / sin theta
= 2 * 600*10^-9 /sin 65°
= 1.3*10^-6m
C.
N = 1/d
So N = 1/1.3*10^-6m
=76.9 lines per micro meter
I would say B.) the blonde hair was a result of the expression of a recessive gene. - the dominate gene is brown hair and the recessive gene is blonde hair...hope this helps
Answer:
Things float when they are positively buoyant, or less dense than the fluid in which they are sitting. This does not mean that an object has to be lighter than the fluid, as in the case of a boat; objects just need to have a greater ratio of empty space to mass than the fluid.

Answer:
Best at conductioning heat- Solid
Explanation:
<u><em>In order for heat to conduct it has to pass from particle to particle.</em></u>
A solid has particles closely compacted so the heat is able to tranfer quickly from particle to particle.
A liquid has isn't as compacted it actually has enough space to slide over each other
A gas has very far apart particles and takes heat longer to transfer from one particle to another.
