If you saw it on a voltmeter, then it stands for "6.5 volts". It tells you that the 'potential difference' or 'electromotive force' between the two points connected to the meter is 6.5 volts.
-- If a 1-ohm resistor were connected between those two points, then 6.5 coulombs of charge would move through the resistor every second. We would say that the "current" through the resistor is 6.5 Amperes, or "six'na half amps".
-- Each coulomb of charge (6.25 x 10¹⁸ electrons) that moves from one of those points to the other one either gains or loses 6.5 joules of energy, depending on which direction it moves.
-- So the resistor would need to shed heat somehow, at the rate of 6.5 watts (6.5 joules per second). If it couldn't do that, then it would go through an interesting series of changes. It would get warm, then get hot, then glow cherry red, then glow bright red, then glow orange, then glow bright yellow, then make a sound like a "POP". Then it would break in the middle, and a little wisp of smoke would come out of it. The two halves of the resistor would sink, sag from their wires, and the current between the two points would stop.
We would say that the resistor had "fused", "failed", "melted", "burned out", or "bought the farm" ... all because it couldn't get rid of heat fast enough.
We have , the motion of a swing that requires 6 seconds to complete one cycle. Period is the amount of time needed to complete one oscillation . And in question it's given that 6 seconds is needed to complete one cycle. Hence ,Period of the motion of a swing is 6 seconds . Frequency is the number of vibrations produced per second and is calculated with the formula of . SI unit of frequency is Hertz or Hz. We know that time period is 6 seconds so frequency =
The speed of molecule decreases and temperature also decreases
Explanation:
Kinetic energy of the molecules of a subsance is directly proportional to the temperature of molecule So as the kinetic energy decrease, temperature also decreases. decreses their speed.
MEMORIZED E=h*v h=6.626x10-34J*s INFORMED v=7.21x1014S-1CALCULATE E=h*v E=(6.626x10-34J*s)*(7.21x1014s-1) The "s" cancels out. s-1=1/s so you get s/s so you are left with Solution 4.78 10-19 J OR .478 aJ <span>Apex - 467 nm ^.^ hopefully thats the correct thing</span>
