Answer:
North pole
Explanation:
According to the law of magnetism:
<em>Unlike poles attract while like poles repel</em>
Since the south pole of the steel is brought near the nail, and the nail is meant to attract the steel magnet, the nail domain realigns itself to produce a pole opposite to the pole of the steel magnet brought near it.
Since the North pole is the opposite of the south pole, the North pole will be at the pointed end of the nail so that it can attract the steel magnet.
The minimum coefficient of friction to avoid slippage of the coin is 0.23.
<h3>
Minimum coefficient of friction</h3>
The minimum coefficient of friction can determined from the maximum speed of the coin.
ma = μmg
mv²/r = μmg
v²/r = μg
v² = μgr
μ = v²/(gr)
μ = (ωr)²/(gr)
μ = ω²r/g
μ = (7.95² x 0.035)/(9.8)
μ = 0.23

Answer:
A devaluation occurs when a country makes a decision to lower its exchange rate in a fixed or semi-fixed exchange rate. A depreciation is when there is a fall in the value of a currency in a floating exchange rate.
Answer:
b
Explanation:
because it is bond made between two metals
The situation wherein the redshift is making the stars
difficult to see is not, in any way, preventing the astronomers from getting a
good view of distant stars.
When light or other electromagnetic radiation from an
object is expands in wavelength, or moved to the red end of the spectrum, the
redshift happens. An increase in wavelength and being equivalent to a lower
frequency and a lesser photon energy, following the quantum theories of light
and the wave is called the redder, whether or not the radiation is inside the
spectrum.
The spectroscopic observations
of astronomical<span> objects can
see redshifts and its value is regarded by the letter z.</span>
