The distance between the charges is 13.86 X 10⁴m
<u>Explanation:</u>
Given:
Force, F = 1.2N
Charge, q₁ = 1.602 X 10⁻¹⁹ C
k = 8.987 X 10⁹ Nm²/C²
Distance, d = ?
According to Coulomb's law:
Substituting the value in the formula we get:
Therefore, the distance between the charges is 13.86 X 10⁴m
When atmospheric pressure is higher than the absolute pressure of a gas in a container.
Answer:
Y = 0.0254 m = 25.4 mm
Explanation:
The formula for the fringe spacing in Young's Double-slit experiment is given by the following formula:
where,
Y = fringe spacing = 0.0176 m
λ = wavelength = 425 nm = 4.25 x 10⁻⁷ m
L = Distance between screen and slits
d = slit separation
Therefore,
Now, for:
λ = 614 nm = 6.14 x 10⁻⁷ m
<u>Y = 0.0254 m = 25.4 mm</u>
I would say Option B) because Option C) is wrong since matter cannot be created. A closed system does not exchange matter so it's not Option D). Since an island is an isolated area, Option A) is wrong.
NO musical instrument produces a 'pure' tone with only a
single frequency in it.
EVERY instrument produces more or less harmonics (multiples)
in addition to the basic frequency it's playing.
The percussion instruments (drums etc) are the richest producers
of bunches of different frequencies.
Fuzzy electric guitars are next richest.
The strings and brass instruments are moderate producers of
harmonics ... I can't remember which is greater than the other.
Then come the woodwinds ... clarinet, oboe, etc.
The closest to 'pure' tones of single frequency are the sounds
made by the flute and piccolo, but even these are far from 'pure'.
The only way to get a true single-frequency sound is from an
electronic 'sine wave' generator.
