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:
during respiration physical and chemical change both are occuring
Explanation:
James braid came up with the term hypnosis
Initial momentum = 2 * m v
so if 1 ball popped out with 2 v momentum would be conserved
but the initial kinetic energy of the two balls is
1/2 m v^2 + 1/2 m v^2 = m v^2
But the kinetic energy of one ball with twice the speed would be
KE = 1/2 m (2 v)^2 = 2 m v^2 thus violating conservation of energy
No, it is not possible for thermal energy to be equal in both bowls.
