Answer:
Explanation:
there are many, many charge carriers moving directly throughout the entire length of the circuit. Current is that the rate at which charge crosses some extent on a circuit. A high current is that the results of several coulombs of charge crossover a cross section of a wire on a circuit. If the charge carriers are densely packed into the wire, then there doesn't need to be a high speed to possess a high current. That is, the charge carriers don't need to travel an extended distance during a second, there just has got to be tons of them passing through the cross section.
Answer:
As the temperature increases, the molecules and atoms move faster
Explanation:
Answer:
c) Equal to R
b) the width of the resonance
Explanation: In general the impedance Z of an electrc circuit is:
Z = R + jX
Now when the circuit is capacitive, the above mentioned relation become Z = R + 1/jwc where ( w = 2πf )
And when the circuit is inductive Z becomes
Z = R + j wl
Resonance condition implies that the reactance created by capacitors are equal at the inductances produced by inductors, in other words the circuit will behaves as it were resistive.
The impedance will be equal to R
The Q factor is[
Q = X/R in which X is the module of either the capacitive or inductive reactance.
Q has an inverse relation with the band width.
Answer:
The quantities that always have equal magnitude for both masses during the collision are change in momentum of the colliding bodies and force exerted by each body
Explanation:
During collision of two bodies, the following quantities are affected;
Kinetic energy of the colliding bodies
change in momentum of the colliding bodies
Force exerted by each body
Two bodies that stick together after collision is inelastic collision.
For inelastic collision, the kinetic energy before collision is greater than kinetic energy after collision.
Change in momentum is zero, that is, momentum before collision is equal to momentum after collision.
According Newton's third law of motion, the force exerted by each body is equal but acts in opposite direction.
Therefore, the quantities that always have equal magnitude for both masses during the collision are change in momentum of the colliding bodies and force exerted by each body
I think it might be D because all waves travel through a medium. I might be wrong though.
