Archimedes principle states
that
F1 / A1 = F2 / A2
F2 = (A2 / A1) * F1
Also, formula for the force is
F = mg. Formula for the area of the cylinder is A = πr^2, therefore we get
F2 = (πr2^2 / πr1^2) * mg
Since the diameter of the
cylinders are 2 cm and 24 cm, r1 = 12 and r2 = 1.
Substituting the values to the
derived equation, we get
F2 = (π 1^2 / π 12^2) * 2400 * 9.8
F2 = 163.3333 N

Answer:
Explained
Explanation:
Photosphere: The lowest layer of the sun is called photo sphere . It is about 300 miles thick from the surface. It is the source of solar flares. It is marked by bright bubbling granules of plasma.
chromosphere emits a reddish glow as the super heated hydrogen burns off but the red rim can only be seen during total solar eclipse.
The third layer of the sun atmosphere is Corona. It can also only be seen during during a total solar eclipse. Temperature in corona can reach as high as 3.5 million degree fahrenheit. As the gases cool they become solar winds.
Somewhere in your book or your notes, you must have met the formula for the
gravitational attraction between two bodies. If you can go back and find it, you
only need to plug your numbers into that formula, and out will pop the answer.
Formula: <u>Force = G (mA x mB) / (distance)²</u>
If everything is in SI units, then G = 6.67 x10⁻¹¹ newton-meter² / kilogram²
You said that
mA = 8.1 kg
mB = 6.5 kg
distance = 0.5 m .
Force = (6.67 x 10⁻¹¹ nt-m²/kg²) (8.1kg x 6.5kg / (0.5m)² =
(6.67 x 10⁻¹¹ nt-m²/kg²) ( 52.65 kg² ) / (0.25 m²) =
<em>1.4047 x 10⁻⁸ newtons .</em>
That's roughly 5.052 x 10⁻⁸ ounce . (5% of one micro-ounce)
