All magnets possess a property called polarity--that is, a magnet's power of attraction is strongest at its opposite ends, usually called the north and south poles. The north and south poles attract each other, but north repels north and south repels south. All magnets attract iron.
Extremophiles occur in all three domains of life: bacteria, archaea, and eukaryotes. Most extremophiles are microorganisms.

Explanation:
Using a free body diagram, it is proved that when the object starts to slide, the tangent of the angle of inclination is equal to the coefficient of static friction:
Hence, you can use that formula directly:
Rounding to the nearest degree that is 31º.
We first calculate the acceleration on the ball using:
2as = v² - u²; u = 0 because ball is initially at rest
a = (36)²/(2 x 0.35)
a = 1850 m/s²
F = ma
F = 0.058 x 1850
= 107.3 Newtons
