What does "a 4-inch candle" mean ?
Is that the length of the candle or its diameter ?
The life of a candle depends on its length, its diameter, the
thickness and starting-length of its wick, the exact substance
of which it's composed ... the type of wax ... and the motions
of the air around it.
I'll always remember the candle shop I visited ... I don't remember
what I was doing in a candle shop, but I was there. There was a
little wax turkey up on a glass shelf, with a tiny tiny flame in the
middle of its back, so tiny that you could easily miss noticing it.
The little sign standing next to the little turkey on the shelf explained
that this was a Thanksgiving candle ... it was lit last Thanksgiving,
and would continue burning until NEXT Thanksgiving, roughly a year later !
Answer:
a 10.6 m/s²
Explanation:
Since F = ma (Force = mass * acceleration), acceleration would be...
a = F/m
a = 302 N/28.6
a 10.6 m/s²
SOLVED DOWN BELOW
Explanation:
In series the same current goes thru both resistors, equiv resistance is 200 ohms, then using ohms law
<em>I = 25/200</em>
<em>I= .125 amps or 125 ma</em>
__________
<em>R= r1 * r2 / r1 +r2</em>
<em>R= 100 * 100 / 100 + 100</em>
<em>R= 10000 / 200</em>
<em>R= 50 ohms </em>

omg halloween lol hows karma, you wasted my points and a chance for others to answer!! :)))
Explanation:
Answer:1) Via heat: ferromagnet materials will lose their magnetism if heated above a point known as the Curie temperature. ... With a strong enough magnetic field of opposite polarity, it is therefore possible to demagnetize the magnet [whether this comes from another permanent magnet, or a solenoid].
Explanation:Unlike permanent magnets, temporary magnets cannot remain magnetized on their own. Soft magnetic materials like iron and nickel will not attract paper clips after a strong external magnetic field has been removed.To restore a permanent magnet, you need to cool the metal (if heated) and expose it to a magnetic field. Coil your copper wire tightly around the piece of metal you would like to restore as a permanent magnet.
