From areas of high potential to low potential. That is, high voltage to low voltage.
This is because strong vibrations will affect the alignment of the magnetic domains within the magnetic material. The domains would change the alignment thus affecting the strength of the magnets which solely depends on the alignment of the domains. The strength of a magnet is the sum of the magnetic fields of all the domains in the magnet. Therefore, the net result will be a weaker magnet or the magnet loosing its magnetism.
Answer:
a = -36.8 m/s/s
Explanation:
Initial speed of the car

finally car will stop after it cover the distance

so we have

here we have



Answer:
It's from crude oil which is black and costly to obtain
Answer:
Explanation:
Given that,
Potential difference of battery is
V = 24V
Total charge battery can transferred
q = 340,000C
Work done by the battery?
Work done is given as
W = qV
Where q is charge in Columbs
V is potential difference in Volts
Then, W = qV
W = 340,000×24
W = 8,160,000 J
Work done by the battery over it's useful life time is 8,160,000J
