Answer:
So, when an electrical charge passes through a resistor, some of that electrical energy is transferred into heat, increasing the temperature. This extra energy causes the particles in the resistor to vibrate more. With these particles moving more, it is more difficult to for the electrons to move through the resistor.
Answer:
I know the first one is C.) 4J. I don't know of the answer for the second oneis suppose to be in N/m form? but I got
2,500N/m
Answer:
It is difficult to magnetize.
Answer:
<em>t = 1.02 s</em>
Explanation:
friction = 0 N (no slipping)
downward force along the inclined plane = F = mgsin(30.8)
F = ma
⇒ a = 9.81 sin(30.8)
a = 5.02 m/s^2
now we have
displacement = s = 2.6 m
acceleration = a = 5.02m/s^2
initial velocity = Vi = 0m/s
time = t = ?
<u>APPLYING THE 2ND EQUATION OF MOTION:</u>
<em> S = (Vi)(t)+0.5at^2</em>
<em>2.6 = 0(t) + 0.5 * 5.02 * t^2</em>
<em>t = 1.02 s</em>
I’m pretty sure it’s ground but I might be wrong. Sorry
